Success with WebSphere and JRules
Goals
Quick Web Service solution for WebSphere Minimize required coding
Benefits
Quickly create and demonstrate JRules MTDS on “unsupported” platform Minimal coding and configuration required
Solution
Use OOB Java Client for RuleApps Web Service Patch the OOB WebService for RAD and WebSphere Use RAD 7.0 to generate Web Service
Situation
Need a WebSphere Web Service for a Java XOM (MTDS) JRules 6.6 does not create a OOB web service for a Java XOM on WebSphere WAS 6.1 does not support JAX-WS 2.0 (need “Feature Pack for Web Services”) RAD 7.0 does not support JAX-WS 2.0 (will be added in RAD 7.5?)

Solution Outline
Use JRules OOB Features…. Create a Client Project for RuleApps
…to Create a WebSphere MTDS Copy classes to a (new) RAD Dynamic Web Project
Copy resources to RAD Dynamic Web Project
Modify the JRules generated classes for RAD
Generate the new Web Service
Deploy and Test

Modify the Generated Classes
Remove all JAX-WS annotation RAD 7.0 does not support JAX-WS PretradecheckswdsRunner PretradecheckswdsRunnerImpl
Change the RuleExecutionException class to general Exception class Web Service wizard in RAD expects default constructor in the exception PretradecheckswdsRunner PretradecheckswdsRunnerImpl
Change the rule session provider to SIMPLE_RULESESSION_PROVIDER No requirement to use the J2SE_RULESESSION_PROVIDER PretradecheckswdsRunnerImpl
Change MBean properties to match new information PretradecheckswdsrulesListener Change the wsdlurl to match the URL (http://localhost:9080/pretradechecks-
webservice/services/PretradecheckswdsRunnerImpl?wsdl)

Add Appropriate Resources
Add <XOM>.JAR to Web App Libraries Add JRules modules to Web App Libraries
<jrules-home>\executionserver\lib\jrules-bres-dsmbean.jar <jrules-home>\executionserver\lib\jrules-bres-session-java.jar <jrules-home>\executionserver\lib\executionserver\applicationservers\websphere6\ jrules-
bres-session-WAS6.jar
Add the JRules xu resource-ref to the deployment descriptor (web.xml)<resource-ref>
<res-ref-name>eis/XUConnectionFactory</res-ref-name>
<res-type>javax.resource.cci.ConnectionFactory</res-type>
<res-auth>Application</res-auth>
<res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>
Add the (PretradecheckswdsrulesListener) listener to web.xml<listener>
<description></description>
<display-name>PretradecheckswdsrulesListener</display-name>
<listener-class>pretradecheckswdsruleapp.PretradecheckswdsrulesListener</listener-class>
</listener>
