  1. 1. SHOW104 Buried treasure: Finding the Hidden Gold in Lotus Notes Data Mark Myers | London Developer Coop Julian Robichaux | panagenda© 2013 IBM Corporation
  2. 2. AgendaOverviewWorking with FeedsIntegrating with IBM ConnectionsODBC, JDBC, and ReportingGenerating Files on the Domino ServerCaveats, Considerations, and Data ScrubbingWhere to Get More Information © 2013 IBM Corporation
  3. 3. Who Are Mark & Julian? Julian – Java/Eclipse application developer at panagenda (panagenda.com) – Developer since before Justin Bieber was born – Notes/Domino since version 4.1 – Speaker at 7x Lotuspheres, various LUGs and View conferences – Twitter: @jrobichaux, Blog: nsftools.com Mark – Member of the London Developer Co-op (londc.com) – Developer from a support background – 12+ years on Domino, 15+ years in IT – Speaker at 2x Lotuspheres, 3x UKLUGs, 1x ILUG – Twitter: @stickfight, Skype: Stickfight, Blog: stickfight.co.uk © 2013 IBM Corporation
  4. 4. Why Are We Here? You have years and years of data stored in your Notes databases – Valuable – Critical? – Historically important Often, that data needs to be accessed from other places – Reports – Intranets/portals – Non-IBM systems What are your options? As it turns out, you have a lot of options… © 2013 IBM Corporation
  5. 5. Tools We Used IBM® Lotus® Notes® version 8.5.3 IBM Lotus Domino® version 8.5.3 Microsoft® Windows® 7 IBM Connections V4.0 Various other software tools mentioned throughout this presentation Most code and techniques we talk about should be applicable to other versions of Notes/Domino/Windows too © 2013 IBM Corporation
  6. 6. Old and New This presentation is an eclectic mix of Old and New, borne out of many many years of Domino programming experience Solutions are based on Ease, Speed and Reliability rather than the latest coding fashion If a solution seems old (more than 2 year old technology) it is because: – Some implementations we see are still being done wrong (or not done at all) – Some people are still on old versions of software – Sometimes the “old” way is still the best way to do things – Everyone is at a different experience level; maybe you’ve never seen some of this before – This stuff still works © 2013 IBM Corporation
  7. 7. About the Sample Database This year’s sample dataset is… Sea Ducks! The Atlantic Flyway Sea Duck Survey, conducted by the U.S. Fish and Wildlife Service, was established in 1991 to record sea duck numbers using near shore (within 700 m of shore) habitats from Cape Breton, Nova Scotia to Jacksonville, Florida. https://migbirdapps.fws.gov/mbdc/databases/afsos/disclaimerafsos.html © 2013 IBM Corporation
  8. 8. About the Sample Database Public domain data and photos from the US Fish and Wildlife service – See the “About this Database” page in the sample database for information, disclaimers, and links A little over 10,000 lines of data (i.e. – individual documents in a view) Various means of grouping and data retrieval – By year – By state – By duck type Some documents also have image files stored in rich text fields So… potentially similar to data you already have © 2013 IBM Corporation
  9. 9. Agenda Overview Working with Feeds Integrating with IBM Connections ODBC, JDBC, and Reporting Generating Files on the Domino Server Caveats, Considerations, and Data Scrubbing Where to Get More Information © 2013 IBM Corporation
  10. 10. What’s a Feed? Structured data – 0-to-N items Parseable format Retrievable via a link or some other automated method Ideally (but not necessarily) semantic – Semantic markup assigns “meaning” to data http://en.wikipedia.org/wiki/Microformat © 2013 IBM Corporation
  11. 11. JSON vs. XML © 2013 IBM Corporation
  12. 12. ReadViewEntries Replace ?OpenView with ?ReadViewEntries in the URL of any Domino view on the web to see the contents as XML – Since Domino 7 © 2013 IBM Corporation
  13. 13. ReadViewEntries Some optional parameters: – CollapseView / ExpandView – NavigateReverse=1 – lists documents in reverse order, starting with the last document – Start=n – indicates which document number to start with – StartKey= / EndKey= – indicates which key in a sorted view to start and/or end with – RestrictToCategory= – indicates which category to display in a single-category view Count=nn – Very important if you want to get ALL the docs in a view – Default is 30, or whatever is specified by “Default lines per view page” on the Domino Web Engine tab of the server (or web site) document – Default maximum is 1000, or whatever is specified by “Maximum lines per view page” OutputFormat=JSON – Displays data as JSON instead of XML A few other parameters too: check Domino Designer help © 2013 IBM Corporation
  14. 14. ReadViewEntries JSON Format © 2013 IBM Corporation
  15. 15. ReadViewEntries XML Format © 2013 IBM Corporation
  16. 16. Notes on Using ReadViewEntries Maximum View Count settings on the server doc might prevent you from seeing all the data in the view You can save the query and refresh the data on demand Categorized views get messy, flat views are better If you need to login, make sure the server is using Basic Authentication (at least for that URL) – Not strictly necessary, but much easier from a programmatic standpoint © 2013 IBM Corporation
  17. 17. Overriding Session Authentication If your Domino server uses session authentication (most do), there is an option to override this and use basic authentication for specific URLs Since Domino 7 – http://publib.boulder.ibm.com/infocenter/domhelp/v8r0/topic/com.ibm.help.domino.admin. doc/DOC/H_OVERRIDING_SESSION_AUTHENTICATION_8847_STEPS.html Must be using Web Site documents for web server access – “Load Internet configurations from ServerInternet Sites documents” enabled on Basics tab of server document – http://publib.boulder.ibm.com/infocenter/domhelp/v8r0/topic/com.ibm.help.domino.admin. doc/DOC/H_R5_WEB_SITE_TO_RNEXT_OVER.html © 2013 IBM Corporation
  18. 18. Overriding Session Authentication Open the “Web Site” document for your server © 2013 IBM Corporation
  19. 19. Overriding Session Authentication• The URL pattern can use * for wildcards (? is treated as a literal character).• If you don’t a wildcard at the beginning and end, the rule might not work the way you expect. © 2013 IBM Corporation
  20. 20. Overriding Session Authentication Optional parameter on the Web Site document to auto-generate a session cookie when Basic Authentication is used in an override rule © 2013 IBM Corporation
  21. 21. Classic Feed: ICalendar Still the best format for dealing with event based data Near universally supported Can be done without 3rd party libraries © 2013 IBM Corporation
  22. 22. Classic Feed: ICalendarWe just need a view. © 2013 IBM Corporation
  23. 23. Classic feed: ICalendar Most ICalendar clients tend to be picky on carriage returns so you need to be careful © 2013 IBM Corporation
  24. 24. Classic Feed: ICalendar ICalendar date time is in the format yyyyMMddTHHmmssZ © 2013 IBM Corporation
  25. 25. Classic feed: ICalendar Then insert the view in a form with the text that wraps the ICalendar Vevents, this text details time zones and such for the calendar as a whole © 2013 IBM Corporation
  26. 26. Classic feed: Web ServicesThe De facto standard for inter-system communication Still seen as a silver bullet by many managers See a new web service as an opportunity to re-define how your data is seen Complex if done badly, simple with a few tricks or the right software © 2013 IBM Corporation
  27. 27. Classic Feeds: Web Services Best Tools – Lotus Domino server! – Liquid XML Studio ( http://www.liquid-technologies.com/xml-studio.aspx ) • Brill visual designer • Powerful but easy to use • Costs a lot from a stingy developer’s point a lot (but worth it) – Soap UI ( http://www.soapui.org ) • The simplest way for humans to interact with and test raw web services • Free for the Lite version © 2013 IBM Corporation
  28. 28. Classic Feeds: Web Services © 2013 IBM Corporation
  29. 29. Classic Feeds: Web Services © 2013 IBM Corporation
  30. 30. Classic Feeds: Web Services © 2013 IBM Corporation
  31. 31. Classic Feeds: Web Services © 2013 IBM Corporation
  32. 32. Custom Feeds: Decisions to Make Data format – XML, JSON, CSV, something else… Data structure – RSS, Atom, something else… – Standard structures are widely supported – Custom structures allow more flexibility Static or dynamic – Caching and performance issues – User-specific information? Do you control the clients? – If not, it might be hard to make changes later © 2013 IBM Corporation
  33. 33. Atom and RSS Standard XML formats for document-based data RSS is simpler to produce and parse – Fewer options – Easy to understand – Great for syndication of news, blogs, and similar Atom is more flexible – Easily extensible for data customization – Read AND write data, if you need to publish – Still primarily for documents, rather than raw spreadsheet-type data Almost any software that calls itself a Feed Reader can consume either type of feed with no problem © 2013 IBM Corporation
  34. 34. Feed Library vs. Build-Your-Own XML and RSS/Atom is easy to break – Character encoding issues – Illegal characters – Unclosed tags – Improperly formatted dates – Missing required elements If you write “raw” XML to a text string for output, test often and add plenty of checks for poorly formatted data Feed libraries take care of the heavy lifting for you – Built-in validation – No need to study the specification documents – Probably slower and more memory-intensive – Usually several megabytes of required code libraries either stored in the database or copied to the server © 2013 IBM Corporation
  35. 35. Example: RSS Feed Generator Database Template included with Domino 7 Easy to use for quick feeds: – Create a new database on the server using the “RSS Generator” template – Fill out a form to point to a view – Point the users to the database URL Reuse the code in your own applications © 2013 IBM Corporation
  36. 36. Example: RSS Feed Generator Database © 2013 IBM Corporation
  37. 37. Example: RSS Feed Generator Database © 2013 IBM Corporation
  38. 38. Example: RSS Feed Generator Database Unfortunately, the <enclosure> item has a hard-coded data type, so it’s only good for docs where all the attachments are the same type © 2013 IBM Corporation
  39. 39. Example: RSS Feed Generator Database © 2013 IBM Corporation
  40. 40. Example: Java Agent Atom Feed A few different Java feed parsing libraries to choose from: – ROME – http://rometools.org – Apache Abdera – http://abdera.apache.org – Apache Wink – http://incubator.apache.org/wink All require several additional libraries – Apache Commons libraries – Java StAX support – Etc. Handle HTTP connections as well as parsing – Authentication too An excellent test client: – DEV HTTP Client (Chrome Plugin) https://chrome.google.com/webstore/detail/aejoelao ggembcahagimdiliamlcdmfm © 2013 IBM Corporation
  41. 41. Example: Java Agent Get Atom Feed © 2013 IBM Corporation
  42. 42. Example: Java Agent Submit Back to Atom Feed Most Atom services (particularly IBM) give examples of what XML they want rather than examples of the code you should use, so we will do the same This is a IBM Connections Blog entry in raw XML:<?xml version="1.0" encoding="utf-8"?><entry xmlns="http://www.w3.org/2005/Atom"><author><name>I Am Funny</name></author><title type="text">Great Duck Joke</title><content type="text">Q: What has webbed feet and fangs? A: Count Duckula</content></entry> © 2013 IBM Corporation
  43. 43. Example: Java Agent Submit Back to Atom Feed An amazingly useful line when you are debugging or testing as it outputs the XML so you can check it against what you should be sending © 2013 IBM Corporation
  44. 44. Example: Java Agent Submit Back to Atom Feed Getting this URL is often the hardest part of dealing with Atom © 2013 IBM Corporation
  45. 45. Example: Useful Extra Lines Add “registerTrustManager” and you can connect to SSL Ports Nice simple login, you just need the user name, password and the root domain you are logging on to © 2013 IBM Corporation
  46. 46. Agents vs. XAgents Java agents are not efficient when using large JAR files attached to agents or script libraries – They are reloaded into memory each time the agent runs – Beware of memory problems Copying the JAR files to the jvm/lib/ext directory on the Domino server keeps them in memory – If your admin allows it – Have to do this with every server the code might run on An alternative is XAgents: XPages written so they run as agents – No UI, except for print statements (“write”, actually) – JARs and Java code attached directly to the database – Much better caching of JAR files – http://www.wissel.net/blog/d6plinks/shwl-7mgfbn – http://www.mindoo.com/web/blog.nsf/dx/17.07.2011101855KLEBRW.htm © 2013 IBM Corporation
  47. 47. Caveats Malformed JSON and XML Character encoding issues Multi-value fields can be tricky Memory issues when using large Java libraries – Or poorly written Java code Make sure you use the right Content-Type HTTP header when you send data – JSON should be “application/json” – XML should be “application/xml” (preferred) or “text/xml” © 2013 IBM Corporation
  48. 48. AgendaOverviewWorking with FeedsIntegrating with IBM ConnectionsODBC, JDBC, and ReportingGenerating Files on the Domino ServerCaveats, Considerations, and Data ScrubbingWhere to Get More Information © 2013 IBM Corporation
  49. 49. Integrating with IBM connections 2 basic forms of integration – Submitting existing data directly into Connections (as demonstrated by the previous Atom examples) – Read data from Domino and displaying it in Connections via a widget © 2013 IBM Corporation
  50. 50. Connections Caveats This is not a Connections session The methods shown in this session are one of many methods of integration rather than specific best practices – Niklas Heidloff (http://heidloff.net) and Mark Leusink (http://linqed.eu) have some good examples – These methods use as few toolkits such as Social Business toolkit/Social business SDK, social enabler as possible. Real life has taught that the best integration environment to build is one where you can get all data if required (Gather all data using service accounts) then compile a result and display to the user. See the related sessions at the end of this presentations for more details and the best practice sessions. © 2013 IBM Corporation
  51. 51. Integrating with IBM Connections Before we start we need to get a database ready to call Java from XPages Move to Package Explorer © 2013 IBM Corporation
  52. 52. Integrating with IBM Connections In The WEB-INF directory Right click and create a new folder © 2013 IBM Corporation
  53. 53. Integrating with IBM Connections Call it “src” in lower case © 2013 IBM Corporation
  54. 54. Integrating with IBM Connections Next add this folder to the projects build path Right click on the root of the project and select “Properties” © 2013 IBM Corporation
  55. 55. Integrating with IBM Connections On the “Source” tab click “Add folder” and add the folder you have created © 2013 IBM Corporation
  56. 56. Integrating with IBM Connections You will see the Folder has moved Right click and select “New” → “Other” Then Select “Java” → “Class” © 2013 IBM Corporation
  57. 57. Integrating with IBM Connections Create the new Java Class © 2013 IBM Corporation
  58. 58. Integrating with IBM Connections OK, Java class created, lets get it some libraries © 2013 IBM Corporation
  59. 59. Integrating with IBM Connections If you are not allowed to use the EXT directory on the server, the you will need to create a new “lib” folder © 2013 IBM Corporation
  60. 60. Integrating with IBM Connections © 2013 IBM Corporation
  61. 61. Integrating with IBM Connections Update (or ask your administrator to) the java.policy file on your server to contain the following grant { permission java.lang.RuntimePermission "getClassLoader"; }; © 2013 IBM Corporation
  62. 62. Now we will add theIntegrating with IBM Connections Atom client code function You need to pass the session into this function as it can’t get its own If you need to you can login here (as described previously) © 2013 IBM Corporation
  63. 63. Integrating with IBM Connections Create a New Script Library © 2013 IBM Corporation
  64. 64. Integrating with IBM Connections Set it as a Normal “Server JavaScript” Library © 2013 IBM Corporation
  65. 65. Integrating with IBM Connections Create a SSJS function to call your Java and pass the results back Pass the “sessionAsSigner” here to give yourself administrator rights © 2013 IBM Corporation
  66. 66. Integrating with IBM Connections – Pulling it together Create a Custom Control © 2013 IBM Corporation
  67. 67. Integrating with IBM Connections Give it a Name © 2013 IBM Corporation
  68. 68. Integrating with IBM Connections Now you can add a repeat control that calls the SSJS function, which in turn calls the Java The Rest of the surrounding boring code is in the demonstration db © 2013 IBM Corporation
  69. 69. Integrating with IBM Connections – Pulling it together Create a New Xpage Library © 2013 IBM Corporation
  70. 70. Integrating with IBM Connections – Pulling it together Add the duckstates_cc custom control © 2013 IBM Corporation
  71. 71. Integrating with IBM Connections – Pulling it together © 2013 IBM Corporation
  72. 72. Integrating with IBM Connections Now that you have an XPage, you need to present it to Connections as a Open Social widget the easiest way of doing this is with a simple domino page. © 2013 IBM Corporation
  73. 73. Integrating with IBM Connections Features like “dynamic-height” are harder to get working using this method (rather than a embedding the widget in connections) but if you have a static sized widget it is the simplest. © 2013 IBM Corporation
  74. 74. Integrating with IBM Connections And add it to your Connections installation © 2013 IBM Corporation

  77. 77. SQL Queries of your Notes Data? Lotus Notes is NOT a relational database – You knew that, right? IBM has a NotesSQL driver – Free download, easy install – Treats Notes Views like SQL tables – Has been updated for Notes 8.5 © 2013 IBM Corporation
  78. 78. From the Notes Client: NotesSQL Free tool from IBM Windows-only (make sure you have the latest version on Windows 7) Set up on each user’s machine (install plus DSNs) Notes client must be installed (version 6.0 or higher) Easy integration with reporting tools like Crystal Reports, MS Excel, and MS Access © 2013 IBM Corporation
  79. 79. Setting up NotesSQL Download from http://www.ibm.com/developerworks/lotus/ products/notesdomino/notessql – Help files are in C:NotesSQLdocs after install After install, the NotesSQL directory and the Notes program directory MUST be in the Windows PATH – You get vague error messages if they’re not Create an ODBC DSN to point to a database © 2013 IBM Corporation
  80. 80. Example of Connecting with MS Excel © 2013 IBM Corporation
  81. 81. Example of Connecting with MS Excel © 2013 IBM Corporation
  82. 82. Example of Connecting with MS Excel © 2013 IBM Corporation
  83. 83. Example of Connecting with MS Excel © 2013 IBM Corporation
  84. 84. Example of Connecting with MS Excel © 2013 IBM Corporation
  85. 85. Optimizing Your Data You will almost certainly want to create one or more “reporting” views – Many columns of data – No categorization – Minimal sorting for better lookup performance – Reasonable column names (check the “Programmatic Access” name for computed column data) If you’re reporting on rich text data, modify the DSN to allow more than 512 characters for rich text fields Read the help docs on performance © 2013 IBM Corporation
  86. 86. NotesSQL Caveats Problems with MS Excel 2003 – Sometimes hangs while accessing or saving data – Access 2003 works fine though – Excel 2007+ also works fine Problems with OpenOffice 2.x – View columns with text values are blank – OpenOffice 3 works, but has problems with very large views Make sure users are using the correct views for lookups – View names are not always obvious in existing databases with lots of views If users are sharing reports/spreadsheets, the NotesSQL DSN must be set up exactly the same for each user © 2013 IBM Corporation
  87. 87. From the Server: Domino JDBC OpenNTF project written by Philippe Riand No Notes client required! Access Notes view data directly from the Domino server using JDBC © 2013 IBM Corporation
  88. 88. How It Works Runs as a server task – Uses DOTS (another OpenNTF project) to allow Java to run as a server task – Domino 8.5.3 or higher Define which views to expose as tables using an XML file in the database Creates a SQLLite “virtual table” for each view JDBC driver on the client reads the data from SQLLite tables on the server Notes SQLLite JDBC Views Tables Driver © 2013 IBM Corporation
  89. 89. Setup: Install DOTS (Windows example) Download from OpenNTF http://openntf.org/p/OSGI+Tasklet+Service+for+IBM+Lotus+Domino Unzip to c:dots Copy these files from “c:dotsbuildwin32" to the Domino program directory: dotsExtMgr.dll, dotsNSFHook.dll, ndots.exe – Or buildwin64, or buildlinux64, or whatever Create the following folders in the Domino program directory: osgi- dots/shared/eclipse/plugins and osgi-dots/rcp/eclipse/plugins Copy these files from “c:dotsbuild" to the Dominoosgi-dots directory: launcher.jar, com.ibm.notes.java.api_XX.jar, and dotssec.jar Copy c:buildcom.ibm.dots_XX.jar to osgi-dots/shared/eclipse/plugins © 2013 IBM Corporation
  90. 90. Setup: Install DOTS Download Eclipse 3.7.x (Indigo) from http://www.eclipse.org/downloads/packages/release/indigo/sr2 – Get the “Report Developers” version, because we’ll be using BIRT later Unzip Eclipse – Use 7-Zip, not the native Windows unzip program Copy required org.eclipse.* files from Eclipse to osgi-dots/rcp/eclipse/plugins – These MUST be from Eclipse 3.6.x or 3.7.x. Other versions of Eclipse might not work, and the versions already in the osgi directory on the Domino server definitely will not work org.eclipse.update.configurator org.eclipse.equinox.common org.eclipse.osgi org.eclipse.core.runtime.compatibility.auth org.eclipse.equinox.preferences org.eclipse.core.jobs org.eclipse.equinox.registry org.eclipse.core.runtime org.eclipse.equinox.app org.eclipse.core.contenttype © 2013 IBM Corporation
  91. 91. Setup: Install DOTS Add the following lines to notes.ini on the Domino server: – NSF_HOOKS=dotsNSFHook – EXTMGR_ADDINS=dotsExtMgr Start the Domino server Type "load dots" at the server console You should get a "Domino OSGi Tasklet Container started" message – If you copied the samples.jar file, you will also get lots of messages every 60 seconds To stop the DOTS service, type "tell dots quit" © 2013 IBM Corporation
  92. 92. Setup: Install JDBC Download from OpenNTF: http://openntf.org/p/JDBC+Access+for+IBM+Lotus+Domino Unzip to c:DomJDBC Copy the following folders from {domino}/osgi/shared/eclipse/plugins to {domino}/osgi-dots/shared/eclipse/plugins : – com.ibm.commons.jdbc_XX – com.ibm.commons_XX Copy the following file from {domino}/osgi/rcp/eclipse/plugins to {domino}osgi-dots/shared/eclipse/plugins : – com.ibm.notes.java.api_XX.jar – If you already have the java.api file from the DOTS install, just remove the existing one and replace it with the one from Domino © 2013 IBM Corporation
  93. 93. Setup: Install JDBC Copy all the plugins from c:DomJDBCupdateSite-dots.zip to {domino}/osgi-dots/shared/eclipse/plugins Copy com.ibm.xsp.extlib.relational.domsql_1.0.0.jar from c:DomJDBCupdateSite- xpages.zip to {domino}/osgi-dots/shared/eclipse/plugins Restart DOTS You should get a "Initializing DomSQL RMI server for Domino" message © 2013 IBM Corporation
  94. 94. Setup: Install JDBC The default JDBC port is 8089, and you need to make sure your firewall allows ndots.exe to use that port – You can change the port number by adding DomSQL_Port=XXXX in notes.ini © 2013 IBM Corporation
  95. 95. Configuring Your Databases Notes databases on the Domino server must be explicitly set up to allow JDBC access to views – Each database set up individually – You can set up a single view, or all views, or a group of views Security – Only expose the views you want to expose – Database ACL is respected As with ODBC, you might want to create special “reporting” views © 2013 IBM Corporation
  96. 96. Configuring Your Databases Open the database in Domino Designer Add the "Package Explorer" view if you dont already have it (Window - Show Eclipse Views - Other - Java - Package Explorer) Expand the database in Package Explorer and go to Web Content - WEB-INF © 2013 IBM Corporation
  97. 97. Configuring Your Databases Create a new folder under WEB-INF called "jdbc“ – Right-click - New - Other - General - Folder Create a new file in the new "jdbc" folder called "views.domsql“ – Right-click - New - Other - General – File – It doesn’t specifically need to be called “views”, it can be anything with a .domsql extension – You can have multiple .domsql files © 2013 IBM Corporation
  98. 98. Configuring Your Databases To expose all views via JDBC, just use this in your .domsql file: To expose specific views, rename views, override column properties: © 2013 IBM Corporation
  99. 99. Configuring Your Databases NOTE: DomSQL uses the "Programmatic Use" name for columns in the view. You might want to override this either in the view itself or using a <column> definition in the .domsql file. © 2013 IBM Corporation
  100. 100. Example: Connect using SquirrelSQL Many programs are available to access data via JDBC One nice (free) one is SquirrelSQL – Java, LGPL – Plugins – SQL code completion – Export SQL query results to CSV, Excel, XML format – http://squirrel-sql.sourceforge.net © 2013 IBM Corporation
  101. 101. Example: Connect using SquirrelSQL Download and Install SquirrelSQL Copy the com.ibm.domino.domsql.driver_XX.jar file to SquirrelSQL/lib Start SquirrelSQL Add a new driver with the following properties: – Name: Domino JDBC Driver – Example URL: jdbc:mysql://<hostname>[<:8089>]/<dbname.nsf>/<.domsqlname>[? <user>=<value1>][&<password>=<value2>] – Class Name: com.ibm.domino.domsql.DomSQLDriver © 2013 IBM Corporation
  102. 102. Example: Connect using SquirrelSQL © 2013 IBM Corporation
  103. 103. Example: Connect using SquirrelSQL Choose the menu option Aliases - New Alias. Create an alias with the following properties: – Name: LS13 Test – Driver: Domino JDBC Driver – URL: jdbc:domsql://localhost/ls13/SHOW104DuckData.nsf/Views (“Views” is the name of the .domsql file) © 2013 IBM Corporation
  104. 104. Example: Connect using SquirrelSQL Choose the menu option Aliases – Connect © 2013 IBM Corporation
  105. 105. Example: Connect using SquirrelSQL Use the Content, Row Count, etc. tabs to view information – Note that column data types are automatically determined Go to the SQL tab to run queries Queries can be exported as CSV, Excel, or XML – Use the “Store Result of SQL in File” toolbar button © 2013 IBM Corporation
  106. 106. Example: Create a BIRT Report BIRT: Business Intelligence and Reporting Tools – http://www.eclipse.org/birt Eclipse-based open-source reporting system – Originally developed by Actuate – Now a top-level Eclipse project Can install stand-alone, as part of an Eclipse installation, or as a runtime for J2EE integration Reports can be published to a reporting server, or exported as PDF, HTML, Excel, and other formats © 2013 IBM Corporation
  107. 107. Example: Create a BIRT Report Since we already downloaded Eclipse 3.7 for Report Developers (which includes BIRT) as part of the DOTS setup, we will use that Launch Eclipse Create a new workspace Go to the workbench © 2013 IBM Corporation
  108. 108. Example: Create a BIRT Report File – New – Other – Business Intelligence and Reporting Tools – Report Project © 2013 IBM Corporation
  109. 109. Example: Create a BIRT Report Give the project a name Click “Finish” Switch to the Reporting Perspective when prompted © 2013 IBM Corporation
  110. 110. Example: Create a BIRT Report File – New – Report © 2013 IBM Corporation

  123. 123. © 2013 IBM Corporation
  124. 124. JDBC Optimization and Tuning SQLLite tables can be created as temporary, memory, or file Sorted columns can be used as indexes Use indexed fields for JOINs Avoid using COUNT in your SQL queries (let the reporting tool do that work) Use the Debug page in the example database for testing – And the NATIVE_TRACE_PERFORMANCE_HINTS option You can create a .jdbc file if you want to add authentication info Read the PDF that comes with the project for more tips © 2013 IBM Corporation
  125. 125. JDBC Caveats Windows-only right now You really should set this up on a separate reporting server, rather than a normal production server – There can be memory issues – The RMI task doesnt shut down properly unless you shut down the entire server. Using default views along with the <view> definitions will result in duplicate tables shown by the reporting client If you have "Connection refused" errors, make sure DOTS is running! – You can load DOTS/JDBC when the server starts up by adding "dots" to the ServerTasks line No connection is info shown on the Domino console If you change your .domsql files, you have to restart the Domino server © 2013 IBM Corporation
  126. 126. Contrast and Compare: NotesSQL vs. Domino JDBC Notes SQL  Domino JDBC – Notes client required – No Notes client required – No server configuration required – Server configuration required – No database configuration required – Minor database configuration required – Server or local databases – Server databases only – XPages integration NOT recommended – XPages integration © 2013 IBM Corporation
  127. 127. AgendaOverviewWorking with FeedsIntegrating with IBM ConnectionsODBC, JDBC, and ReportingGenerating Files on the Domino ServerCaveats, Considerations, and Data ScrubbingWhere to Get More Information © 2013 IBM Corporation
  128. 128. Issues Creating Files on the Domino Server Sometimes you need to create a file directly on the Domino server – Dynamic file generation for web page – Create a file and attach it to an email – A present for your Domino Administrator With agents, you need to have: – Unrestricted Access in the Security section of the server doc – Restricted operations allowed in Agent security With XPages, you need to have: – Permissions set in the /jvm/lib/security/java.policy file There are creative ways around this in certain situations… © 2013 IBM Corporation
  129. 129. Example #1: Streaming a File from an XPage In the first example, we want to generate an Excel spreadsheet on-the-fly and send it directly to a web user From a process perspective, it will be: – The user clicks a link that says “Download Spreadsheet” – The server creates a spreadsheet based on a view or custom parameters or whatever – The user gets the “Where would you like to save this file” prompt There are ways to trick Excel into thinking an HTML table is actually a spreadsheet file – See David Leedy’s http://xpagescheatsheet.com for an example We want to generate an actual binary file and send it for this example © 2013 IBM Corporation
  130. 130. Apache POI for Writing Native Excel Spreadsheets http://poi.apache.org Java only, no DLLs or MS Office installations required You only need to make a single JAR file (poi-XX.jar) available to your code Creates an actual binary Excel file, not a text file that can be opened with Excel – Can read as well as write – Formats: XLS, XLSX, DOC, DOCX, PPT, PPTX – Also additional libraries for Visio, Publisher, and TNEF Interesting examples in the HSSF (Office) and XSSF (Office XML) samples file – Multi-sheet calendar – Formatting, calculations, and freeze-panes – Convert DOC or XLS to HTML for web display © 2013 IBM Corporation
  131. 131. Attach the POI JAR File to the Notes Database We will attach the Apache POI JAR file directly to the Notes database so it can be used by the XPage Open the database with the Package Explorer view – Like we did in the JDBC example Navigate to the WebContent/WEB-INF folder Right-click WEB-INF and choose New – Other… © 2013 IBM Corporation
  132. 132. Create a New Folder in WEB-INF called “lib” © 2013 IBM Corporation
  133. 133. Copy the POI JAR File to the New “lib” Folder Right-click the new “lib” folder and choose the menu option “Import” © 2013 IBM Corporation
  134. 134. Find the POI JAR File and Attach It © 2013 IBM Corporation
  135. 135. Add the “lib” Folder as a Source Folder © 2013 IBM Corporation
  136. 136. Add the POI JAR File to the Build Path This allows the Java file we will write to use the JAR for compilation © 2013 IBM Corporation
  137. 137. Add the POI JAR File to the Build Path © 2013 IBM Corporation
  138. 138. Create A Java Class Next we need to create a Java class that can be used by an XPage Java design element introduced in Notes 8.5.3 For older versions, you can create a class directly in the “lib” folder in Package Explorer © 2013 IBM Corporation
  139. 139. Create A Java Class Needs a package name and a class name © 2013 IBM Corporation
  140. 140. Create A Java Class Add code to generate an Excel file using POI © 2013 IBM Corporation
  141. 141. Create A Java Class The code writes to an OutputStream provided by the caller (SSJS from an XPage) © 2013 IBM Corporation
  142. 142. Create an XAgent XPage Create an XPage with a catchy name © 2013 IBM Corporation
  143. 143. Create an XAgent XPage We need to modify the source of the XPage to turn this into an XAgent – http://www.wissel.net/blog/d6plinks/shwl-7mgfbn This allows us to set the HTTP response headers, get a handle to the XPage OutputStream, and call the Java code we just wrote © 2013 IBM Corporation
  144. 144. Create an XAgent XPage © 2013 IBM Corporation
  145. 145. When Called from a Browser: © 2013 IBM Corporation
  146. 146. What Just Happened? The XPage used HTTP headers that indicated that this was an Excel file, and it was a file download The XPage called the Java class, passing it a reference to a Notes View and the XPage OutputStream The Java code generated a spreadsheet in memory and wrote the bytes directly to the XPage OutputStream The browser client received a file without ever having the file written to disc © 2013 IBM Corporation
  147. 147. Example #2: Generating and Emailing a PDF In the second example, we will generate a PDF on-the-fly and send it as an email attachment We will use an agent, so you have plenty of different ways to call it Options for accessing a JAR file from an agent: – Attach directly to an agent – Attach to a script library – Add to the jvm/lib/ext folder on the server The trick here will be attaching to an email (or any Notes document really) without creating a file on the server © 2013 IBM Corporation
  148. 148. Java PDF Libraries Several to choose from: – Apache FOP – Apache PDFBox – PDFJet – iText – Many others… Always check the license Lowagie iText is an excellent option – Initial release in 1999 – Currently on version 5.x (although it jumped from 2.1.7 to 5.0.0 in 2009) – Open-source licensed as AGPL in version 5.0, dual-licensed as MPL/LGPL for version 2.x – http://itextpdf.com © 2013 IBM Corporation
  149. 149. Options for Creating a New PDF in iText Generate the PDF from scratch – Create a PDF doc in memory – Add formatting, paragraphs, images, etc. – Save to a file Use an existing PDF as a template – Interesting technique described by Jake Howlett (codestore.net) – Create a template doc in Symphony or Word or whatever, and save to a PDF – Open the PDF template file in iText – Add paragraphs, images, etc. as above – Save to a file © 2013 IBM Corporation
  150. 150. Creating a Template To generate this stunning template: – I created a document in OpenOffice – Added a headline and a graphic – Used the “Export as PDF” option © 2013 IBM Corporation
  151. 151. Creating the Java Agent We need to create a Java agent and attach both the PDF template and the iText JAR file to it © 2013 IBM Corporation
  152. 152. Add the PDF Template to the Agent © 2013 IBM Corporation
  153. 153. Add the JAR File to the Agent © 2013 IBM Corporation
  154. 154. The Agent Should Look Like This © 2013 IBM Corporation
  155. 155. Agent Code (Generate the PDF) © 2013 IBM Corporation

  157. 157. Agent Code (Generate the PDF) © 2013 IBM Corporation
  158. 158. Agent Code (Attach the File) The PDF generation method returns a byte array. Now we need a way to write a byte array to a RichTextField. © 2013 IBM Corporation
  159. 159. Agent Code (Attach the File) © 2013 IBM Corporation
  160. 160. The Final Result You can certainly make it look prettier than this iText has a lot of options – Text styles – Tables – Images – Barcodes © 2013 IBM Corporation

  162. 162. Understand the Requirements The scenario: someone says “I need that data” Questions you should ask: – Is this an actual requirement? (sometimes its not) – What are you doing with the data? – How often? – What else will you need? Understand sorting, grouping, categorization Is it for reporting, app integration, or migration? Don’t set yourself up for failure Reliability Reliability Reliability © 2013 IBM Corporation
  163. 163. Understand the Users Is this for a person, a department, or a committee? Are you working with another developer, or a lesser being? Does the user have a specific requirement or is this a fishing expedition? Have them walk you through the entire story of what they need – Maybe they really need something different than what theyre asking for – Users dont generally know what their options are If the user fails, you have failed Data feeds loose their WOW factor very quickly and become utilities just like electricity: under-appreciated but completely indispensable © 2013 IBM Corporation
  164. 164. How Much Code Should You Write? As little as possible with out sacrificing reliability Always consider the "no-code" option first – View export or copy-as-table – NotesSQL – ReadViewEntries (if its another dev who needs it) – No-Code means theres less to break How often do you think the requirements will change? – They will always change at least once – Frequent changes == spend time upfront writing flexible code Are you dealing with rich text or attachments? The older the data, the more messed up it will be © 2013 IBM Corporation
  165. 165. Try Not to Become a Report Writer Try to make your code run without maintenance or constant updating Try very hard to keep a separation between data and reports – You are in charge of data – Someone else is in charge of reports – This is even true for migrations Business users probably know the data better than you anyway Writing reports is a slippery slope – "Can I have another one sorta like that, but...?" – "Just like this, but weekly instead of monthly." – And just one more... – And just one more... You gotta do what you gotta do, just watch out – Data is plenty of work all by itself © 2013 IBM Corporation
  166. 166. Normalizing and Scrubbing Data Consider which fields could be categories – That data needs to be consistent Are numbers and dates really numbers and dates? – Youll need to run pre-exports Fix it in the database or in the export? © 2013 IBM Corporation
  167. 167. Use a Dedicated Report Server when Possible Should it be replicated or copied data? Make sure replicated data is one-way unless it specifically needs to be otherwise Sometimes copies are better – No risk of deleting/changing production data – Re-run processes over and over and always expect the same data Much less concern over slow processes, hangs, crashes Admins more willing to "loosen" security – Agent permissions – Java security file – Installing external JARs, DLLs, etc. © 2013 IBM Corporation
