Creating a Web service project for RuleApps for WebSphere Application Server V7

Technote (FAQ)


Question

JRules comes with an out of the box Web service project generator for Tomcat, Websphere CE and JBOSS. JRules creates Monitored Transparent Decision Services (MTDS) which are integrated into the Rule Execution Server (RES). Since WebSphere Application Server V7 supports JAX-WS 2.1 is it possible to have the generator working for this application server ?

Answer

JRules along with the out of the box feature provides an extensive API in order to create your own Client for ruleApps project generator. This API involves eclipse UI, in order to create your own wizard and code generation API using Velocity.

To illustrate this API you can use the following sample to generate a Web Service project for WebSphere Application Server V7.

Upon invoking the New Client Project for RuleApps wizard you will then be offered the possibility to select Web Service for WebSphere AS V7:


The generated java project comes with an ant build.xml script that provides a target deploy-ruleapp to deploy the ruleapp to the specified WebSphere RES Configuration and a target create-ear to generate the webservice application ready to install in WAS 7.

Deploy the EAR file generated in the folder war so that you have a fully working application.

If you elect to generate the web service as a Monitored Transparent Decision Service (MTDS) you will be able to use the RES console to monitor the execution :


New For WebSphere Operational Decision Management

Because you can deploy the java XOM as a resource along with the ruleapp all your rulesets can know be used as a Hosted Transparent Decision Service (HTDS). This is recommended.

If you want to deliver a web service for your application WODM now provides an HTDS implementation for WebSphere Application Server, using a XU J2SE implementation.

The attached sample can be used to create a MTDS using the XU Connection Factory installed in WebSphere Application Server.
