  49. 49. 4 50
  50. 50. Quickstart WorkshopQuickstart Workshop Time & Place: 6 days in June 2011 in Bonn / Germany Team: 2 architects/developers from WSO2 about 4 architects/developers from T-Systems Goal: Proof of concept for the required features
  51. 51. Quickstart Workshop Installation really simple – just unzip, change ports, and run! only 4s per ESB plus 30-60s to start up
  52. 52. Quickstart Workshop ESB Management Console Pitfalls:  only one login cookie per host in a browser  … and we used ssh port forwarding to localhost maybe use several hostnames per host  SSL Certificates and hostname vs. DNS name vs. IP  symptom: empty soap request templates using hostnames worked for us
  53. 53. Quickstart Workshop SOAP Proxy straight forward may include WSDL Pitfalls: references to XSDs set schemaLocation in <xs:import> reachable by the browser vs. reachable by the ESB
  54. 54. Quickstart Workshop <?xml version="1.0" encoding="UTF-8"?> <proxy xmlns="http://ws.apache.org/ns/synapse" name="Soap2SoapProxy" transports="https http" startOnLoad="true" trace="disable"> <target> <endpoint> <address uri="http://1.2.3.4:8080/service/soap" format="soap11"/> </endpoint> <inSequence> <log level="full"/> </inSequence> <outSequence> <log level="full"> <property name="out" value="out"/> </log> <send/> </outSequence> </target> <publishWSDL> … </publishWSDL> </proxy> </xml>
  55. 55. Quickstart Workshop HTTP GET Proxy simple <rewriterule> <action value="" regex="/services/MyProxy" type="replace" fragment="path"/> </rewriterule>
  56. 56. Quickstart Workshop Restful HTTP POST Proxy set ContentType, messageType, HTTP_METHOD trivial Pitfall: POST parameters got lost fixed by WSO2
  57. 57. Quickstart Workshop HTTP SOAP to GET Proxy extract variables via xpath <enrich> <source clone="true“ xpath="//query-string/text()"/> <target type="property" property="POSTFIX"/> </enrich> build URL <property name="REST_URL_POSTFIX" expression="fn:concat(service/insert?,get-property(POSTFIX) )" scope="axis2"/>
  58. 58. Quickstart Workshop Custom Protocol (TCP) Proxy Implement and deploy two Java classes: custom MessageBuilder custom MessageFormatter requires axis2-wso2.jar quite easy
  59. 59. Quickstart Workshop Portability of ESB configuration in filesystem: simple copy in Governance Registry: export/import very nice and simple! Pitfalls:  ESB must be running when the files are deployed, otherwise they are never read  Resources must be deployed first, otherwise proxy definitions may complain about missing files
  60. 60. Quickstart Workshop Filtering and Dynamic Routing <filter xpath="fn:number(get-property(a)) > 10"> <then> <send /> </then> <else> <header name="To" expression="get-property(ENDPOINT)"/> <send/> </else> </filter> clean, but still verbose compared to non-xml languages “if ($a > 10) send(); else send(to => $endpoint)“
  61. 61. Quickstart Workshop Mapping based on DB table <dblookup> <connection> <pool> <password>wso2</password> <user>wso2</user> <url>jdbc:mysql://192.168.3.4:3306/wso2</url> <driver>com.mysql.jdbc.Driver</driver> </pool> </connection> <statement> <sql>select mapped_id from mapping_table where id = ?</sql> <parameter expression="get-property(ID)" type="VARCHAR"/> <result name="mapped_id" column="mapped_id"/> </statement> </dblookup>
  62. 62. Quickstart Workshop Sequence Number Generation via database lookup
  63. 63. Quickstart Workshop Random Number Generation – Javascript <inSequence> <script language="js"> var randomnumber = Math.floor(Math.random()*10); mc.setProperty("GeneratedID", randomnumber); </script> <xslt key="IdMapper.xslt"> <property name="NEW_ID_VALUE" expression="get-property(GeneratedID)"/> </xslt> </inSequence>
  64. 64. Quickstart Workshop Traffic Shaping Throttling at Service Level Throttling at Mediator Level <throttle>-Sequence Policies Prioritization <priorityExecutor>
  65. 65. Quickstart Workshop Message Handling Buffering via JMS queue e. g. Apache qpid, ActiveMQ Resend Dead letter queue
  66. 66. Quickstart Workshop SSL the usual steps for handling certificates otherwise very simple
  67. 67. Quickstart Workshop WS-Security the usual steps for handling certificates and some stuff to declare the policy but otherwise quite simple
  68. 68. Quickstart Workshop OpenID ESB as an OpenID provider SAML ESB as a security token service quite some stuff to do SAML2 single sign on
  69. 69. Quickstart Workshop Business Activity Monitoring WSO2 BAM server ESBs cache and send events to BAM e. g. count by xpath expression
  70. 70. Quickstart Workshop Benchmarks with JVM memory settings increased up to 1680 req/s for SOAP proxy with client/ESB/backend running in VMs on a single host with 2 x Xeon X7460  difficult to measure on VMs at least reasonable fast Pitfalls:  the ESB may be faster than your client or backend
  71. 71. Quickstart WorkshopResult of the Quickstart Workshop: WSO2 Components really work fineFinal Result: Let‘s try and take WSO2 all necessary features sufficiently mature relatively lightweight very good personal support
  72. 72. 5 73
  73. 73. ESB ProxiesBack to the real world…

  75. 75. ESB Proxies Automatic ESB installation unzip, change ports etc. delivery built by Jenkins Automatic service installation One script to set up everything from scratch
  76. 76. ESB Proxies Task #1: Proxies for existing SOAP services 33 services, 159 XSDs modelled in Enterprise Architect WSDLs generated via EMF scripts (xtend/xpand)
  77. 77. ESB ProxiesStrategy: convert existing WSDL/XSDs to ESB proxy service definitions by XSLT called by ant customized by a host-specific config file with URLs deploy to the ESB via file copyPitfall:  Do not use subdirectories for XSDs!
  78. 78. ESB Proxies Task #2: Proxy for another SOAP service (task #2) simplePitfalls:Every external real-world service seems to be a little different  namespaces, path conventions, casing, dependencies on external XSDs…
  79. 79. ESB Proxies Task #3: Proxy for non-XML HTTP POST and GET service use URL rewrite set body via <enrich>Pitfalls:  Make sure to set no-proxy in your browser. And make sure the browser cares.  Don‘t be fooled by your browser‘s cache. Use TcpMon!
  80. 80. ESB Proxies Task #4: Proxy with Transformation define XSLT mediators for in and out sequences generate ID via JavaScriptPitfalls:  Enough. XSLT is designed for simple transformations, not as a comfortable full-featured language.  Make sure your service is redeployed when necessary. Changing just an XSLT may not be sufficient.
  81. 81. ESB Proxies Task #5: Proxy for binary XML one proxy for both XML and WB-XML use ApplicationXMLBuilder / -FormatterPitfalls: It‘s simple as soon as you have found the right builder/formatter and the right options.  DISABLE_CHUNKING was required.
  82. 82. ESB Proxies Task #6: Proxy for POST with Query Parameters simplePitfalls:  Hit a bug - Query Parameters got dropped inSequence works fine if an URL rewrite is inserted Fix provided by WSO2
  83. 83. ESB Proxies Result: Everything works so far! after fixing a bunch of simple problems
