  • ADFBCGroovy, groovy, groovy.List validators die je definieert op view assessors. Bij een entityObjectAttribute Business rule kun je een Listvalidator baseren op een view accessor. Dit kan handig zijn.LibraryShared property voor EO's en VO's. In verband met ADF BC Libraries. Alleen de objecten met LibrarySharedproperty = true kunnen worden gebruikt in de projecten die deze library importeren. Default staat deze property op true, dus zullen alle objecten altijd zichtbaar zijn. Door selectiever gebruik te maken van deze property blijven je libraries schoner. ADFFACESIn ADF 11g-R2 heb je de activeRowKeyproperty. Deze stelt je in staat om in een tabel met de click to edit mode een rij programmatisch editable te maken (zonder te clicken). Als de rij niet zichtbaar is dan wordt hier automatisch naar toe gescrolled. Zie ook : http://technology.amis.nl/blog/13314/adf-11g-r2-using-the-activerowkey-propertyIn ADF 11g-R2 heb je af:formatString en af:formatNamed. Daarmee kun je parameters (maximaal 4) gebruiken in EL expressies. formatString heeft 1 parameter, formatString2 heeft er 2, en zo verder tot formatString4. Hetzelfde geldt voor formatNamed; zie ook http://download.oracle.com/docs/cd/E16162_01/web.1112/e16181/gs_jdev.htm#CHDDAICC

  • Some developers don't know the Completion Insight has 2 modes
  • Problem here is it hasn't filled in the left hand side of the assignment .... what types was it meant to return?In this examples it's easy to guess, but what if the function was declared in some other class? It's painful to have to navigate to that class and come back
  • Instead if the user presses Ctrl – Space twice
  • ....the Completion Insight changes modes
  • On selecting an entry, it will now do both sides of the expression+ bonus it completes the statement too with a semicolon
  • Even though we have a rich editor for business components, there are hidden properties only revealed in the Property InspectorThe highlighted option when used, with the ADF BC components are deployed as an ADF Library, if this is set to true, the component will not be available to the consuming application.

  • ViewObject for Candidate Managers (ViewCriteria with one bind parameter PartialName) Application Module Impl method (in Client Interface): findCandidateManagers(partialName) return row[]Action (Operation) Binding for that method in pageManaged bean that implements suggestions signature, executes operation binding and returns the results(pretty serious: database access after each key stroke!)

  • ADF IN LARRY‟S KEYNOTE ON ORACLE OPEN WORLD 2009 AND 2010
  • THE TABLE • ADF Faces Rich Table (& Panel Collection) – Displays ADF Model data bound collection, bean array, List, ResultSet, RowSet and more – Dynamic Table Configuration & Change Persistence • Rearrange, resize, hide/show columns, freeze columns – Post-load or Lazy Data Fetch – Fetch data rows upon scroll – Filter & Sort – Read-Only and Click-to-edit – [single or multiple] Row and Column Selection – Header, Footer, Column Grouping, DetailStamp – Many, many predefined facets – Export data set, Email & Print mode
  • ACTIVE ROW KEY • Property on table that is „click to edit‟ • EL expression that resolves to the primary key of the row that should be displayed as editable – Table will scroll that row into view
  • "SMART" COMPLETION INSIGHT Ctrl-Space (x 2)

  • JDEVELOPER GO TO SHORTCUTS • Go to Class: CTRL - • Go to File: CTRL ALT - • Find usages: CTRL ALT u – For class, method, EO and VO Attribute, …
  • MORE BEST SHORT CUTS… • CTRL Shift Space: parameter insight • CTRL = : list of recently opened files • CTRL Space: completion insight • CTRL Space (2x): declaration insert • CTRL /: selection commented • CTRL Shift C: copy file path to Clipboard • Alt Home : select file in „tree‟
  • DATA VISUALIZATION
  • THE RIGHT MOUSE CLICK • ContextMenu client listener and Popup (menu and window)
  • POPUP MAGIC
  • EXAMPLE: ADDING FANCY BALLOON HELP • Create a popup with a noteWindow child to contain the fancy help content • Add a showPopupBehavior tag to the inputText that we want to add the help to
  • EXPRESSION LANGUAGE • IoC: Injection of Value and Listener into page • Dynamic, context sensitive behavior • Extension points – Custom Functions invoked from EL – Integration of Spring Beans – Custom EL Resolver • To resolve values from property files, ….
  • EVEN MORE DECLARATIVE ADF DEVELOPMENT – WITH JHEADSTART
  • PROGRAMMATIC CROSS TIER INTERACTION Web Browser JEE Application Server
  • Client Server (middle tier) Database JavaScript Components ComponentsBeans & Objects activeOutputText Active Data Model activeOutputText push serverListener Bean Load JSON, CSS, Image, XML, JSRequest data or Push message push (DB QRCN) Object clientListener component serverListener partial page refresh partialSubmit autoSubmit JavaScript Function Queue Custom Event component component manipulate poll setPropertyListener user or programmatic action add JS to execute (ERKS) add components as partial target ERKS ‘ppr script’ actionListener, valueChangeListener, …Listener component component Full page reload CLIENT SERVER INTERACTIONS VV.
  • USE SETPROPERTYLISTENER TO PUSH DATA TO THE SERVER • The setPropertyListener will pass from value to the to target when type event occurs on parent – A very simple way to inform the server about an event and the data associated with the event – Supported types: action, focus, poll, query, rangeChange, selection, sort, rowDisclosure, valueChange and many more <af:image id="removeFromSetImage“ source="/images/removeFromSet.png“ shortDesc="Remove from Shopping Basket"/> <af:setPropertyListener from="#{item}“ to="#{shoppingBasket.itemToRemove}" type="action"/> </af:commandLink>
  • SERVERLISTENER FOR CUSTOM AJAX (BACKGROUND CLIENT TO SERVER PUSH) • A serverListener associates a server side method with a client side custom event – This allows JavaScript functions to call a server side method by queuing an event – A custom event carries a payload
  • ADF ACTIVE DATA SERVICE – SERVER PUSH TO CLIENT • Push: server sends messages to client • ADF Active Data Service enables UI components to be „automatically refreshed‟ when server side events occur • Active UI Components include Table, Image, OutputText, DVT Components – Based on BAM Data Control – Based on Custom Beans that extend ActiveAdapter • Nudge: push-to-refresh • Note: client-2-client push can easily be implemented as client-to-server-followed- by-server-to-client push Web Browser JEE Application Server
  • AUTO-PPR FOR IMMEDIATE REFRESH OF DATA BOUND COMPONENTS • To have ADF automatically refresh data bound components when underlying value binding has changed its value • Set changeEventPolicy=ppr on iterator – Refresh as piggy back on any request cycle – No partialTriggers attribute required!
  • CROSS TIER PUSH Web Browser RDBMS JEE Application Server trg job servlet activeOT evt lsnr Cache refresher table
  • THE “HISTORY” FEATURE IN JDEVELOPER • Quick comparison of file with previous states – Can leverage Source Code Control system (Subversion, CVS) but also maintains local file history – The compare feature is ‘XML aware’ • Revert to a previous state of a file
  • MARRYING FORMS AND ADF TOGETHER – MIGRATE WITH (i/o FROM) FORMS TO ADF • OraFormsFaces leveraging the JavaScript-Applet bridge for two-way event exchange
  • ADF BC PROPERTIES Property Inspector
  • LIBRARY PRIVATE
  • JAVA AND JEE • ADF is a framework on top of Java, JEE and JVM • Anything that is/extends/runs on one of these is potentially usable with and relevant for ADF • Zillion frameworks and libraries – iText (PDF), Apache POI (Excel), Jasper Reports, BIRT – Spring (IoC, AOP, Acegi/Security, Social, ..) – Apache Commons, Google Collections, Joda Time • Software Engineering – Test (Junit, EasyMock), build (Ant, Maven), check/QA (FindBugs, CheckStyle, Sonar), • JEE facilities in WLS including JMS, WS* & RS, JMX… • Dynamic JVM languages: Groovy, Scala, JRuby, … • Java 7 SE and beyond • Java FX?
  • PREPARE SESSION • Before any other database communication is performed during the processing of a request … • ADF BC will execute the prepareSession() method that you can override in ApplicationModuleImpl • This is the perfect place to – Reset package state – Set application and client info – Set application context • User details, current session context, view filter conditions (real or poor man VPD) – Fetch any events published inside the database Database ADF BC AppMod
  • CHALLENGE • Create a Sliding Tile puzzle that tiles up an image in a configurable number of tiles • Using drag and drop, the user can reassemble the image
  • STEPS • Create Servlet that produces tiles from a JPEG image – Parameters: image name, tile factor, x and y • Create PanelDashboard with panelBoxes with richImage components – That request their source from the servlet corresponding to their position in the grid • Bind the PanelDashboard and dynamically create the panelBox components • Allow user to set the tile factor and choose the image – Use a Carousel for image selection

  • PROGRAMMATIC VIEW OBJECT • It walks, talks and looks like a „regular‟ View Object – (regular being based on Entity Objects or SQL Query) • But it is entirely fueled by custom written overridden Java methods – possibly without database connection – A bit like a View with Instead Of trigger – against a Collection based Table Function and PL/SQL API • Programmatic View Objects can be used as normal in a Data Control for binding ADF Faces components • Normal rich declarative ADF BC data binding can be provided to UI developers for data sources such as – WebService, JMS Queue, Memory Grid, Document Management System, Email, cross session data, … • Note: with the evolution of the Bean Data Control, some of the use cases will fade away
  • THE ROOT OF AJAX Suggestions
  • AUTO SUGGESTIONS • User is entering a field – As she types characters, suggestions can be presented for what the full entry should read • Based on a list of allowable values, based on previous (popular) entries or anything really – User can pick a suggestion for ‘short-cut typing’ • Auto suggestions can be model-driven (declarative) or custom – And can do things beyond plain list based suggestions
  • INTRO • Google Suggest set off the AJAX hype in anger • Many implementations for a „suggestions‟ feature in ADF 10g and 11g have been created – Using custom JavaScript or libraries like Jquery • With PS1, ADF 11g introduced a native component for „auto suggestions‟ – The <af:autoSuggestBehavior> component, to be included in inputText or inputListOfValues or inputComboboxListOfValues
  • MODEL DRIVEN SUGGESTIONS • The suggestions can be derived declaratively from List of Values reference on a VO Attribute • Steps: – On ViewObject • Create ViewAccessor (for list values) • Create List of Values for Attribute • Link LoV to ViewAccessor – In Page • Add InputListOfValues component based on attribute • Add af:autoSuggestBehavior with suggestions based on List of Values Binding’s suggestedItems
  • IN PAGE:
  • CUSTOM SUGGESTIONS • Auto Suggestions can be provided by managed bean that implements signature: – List getSuggestions( String currentValue) • And the List returned is really List<SelectItem> • Potential use cases – Based on some (application wide) cached collection (of previously entered ?) values – Retrieve values from WebService, file, … – Use common abbreviations, codes • Country code, airport – Show translations in other languages
  • STATIC LIST OF COUNTRIES Suggestions
  • SUGGESTIONS … OR? • Suggested Values do not need to be suggestions in a very literal sense – What you see may not be what you get – The SelectItem as a label (WYS) and a value (ISWYG) • Examples: – Add words to field instead of replacing value – Perform selected operation on value – Show an updated indicator based on the value
  • PAGE TEMPLATE • Turns page layout inside out: – the page references the template – the page template determines the overall structure – the page provides the content for the designated areas in the template (through the facets) • Can be dynamically, context-sensitively selected using an EL expression • Can also be used for areas within a page – With multiple page templates used within the same page – More an area template than a page template to define UI Design Patterns • Tree-with-Detail-Form, Table-and-Chart, Master-Form- Detail-Table, Search block-Results table…
  • USING MULTIPLE PAGE TEMPLATES • Two templates: mainpage and Table-Form template
  • OTHER PAGE CONSUMING THE TEMPLATE(S)
  • CHANGING THE MICRO-TEMPLATE
  • SUMMARY • Twinkle, twinkle little stars… – #1 nugget – #2 nugget – #3 nugget • Don‟t give up [too soon] – There is more in ADF than meets the eye – There is a world of Java/JEE to leverage – There is a community to lean on • Scan release notes and monitor blog-o-sphere for valuable new (and re-discovered) nuggets • Share! Yes, you too! Your findings are just as valuable. – Participate in EMG and OTN Forum discussions, write blog articles, present in conferences, …
