[jboss-dev-forums] [Design of JBoss ESB] - Problem in Content Based Routing

[Neha29]

I want to perform Content Based Routing. I want to give my custom object for the rules to execute the action.I am sending a serialized java object using jms .
But i am unable to get the right output.

My JBossesb.xml snippet is


  | 
  |  <services>
  |   <!--  ESB CBR Service -->
  |   <service category="MyFirstCBRServicesESB" description="ESB Listener" name="FirstCBRServiceESB">
  |    <listeners>
  |     <!--  Gateway -->
  |     <jms-listener busidref="quickstartGwChannel" is-gateway="true"
  |      maxThreads="1" name="the-gateway"/>
  |     <jms-listener busidref="quickstartEsbChannel" maxThreads="1" name="XPathContentBasedRouter"/>
  |    </listeners>
  |    <actions mep="OneWay">
  |     <action name="print" class="org.jboss.soa.esb.actions.SystemPrintln">
  |           <property name="message"
  |                    value="Message beforeeee Routing"/>
  |     </action>
  |     <action class="org.jboss.soa.esb.actions.ContentBasedRouter" name="ContentBasedRouter">
  |      <property name="destinations">
  |       <route-to destination-name="express"
  |        service-category="ExpressShipping" service-name="ExpressService"/>
  |       <route-to destination-name="normal"
  |        service-category="NormalShipping" service-name="NormalService"/>
  | 	   <route-to destination-name="test"
  |        service-category="Test" service-name="TestService"/>
  |      </property>
  |         <property name="ruleReload" value="true"/>
  |      <property name="ruleSet" value="SimpleCBRRules"/>
  | 	 <property name="object-paths">
  |     	<object-path esb="body.Task" />
  | 	</property>
  | 	 
  |     </action>   </actions>
  |   </service>

My Rule file is



  | 
  | package com.jboss.soa.esb.routing.cbr
  | 
  | #list any import classes here.
  | import org.jboss.soa.esb.message.Message;
  | import org.jboss.soa.esb.message.format.MessageType;
  | import task.Task;
  | 
  | //expander XPathLanguage.dsl
  | 
  | #declare any global variables here
  | global java.util.List destinations;
  | 
  | rule "Routing Rule using XPATH"
  | 
  | 	when
  | 		t : Task(status == 1)
  | 		
  | 	then 
  | 	System.out.println("EXPRESS");
  | 	destinations.add("express");
  | 
  | 	
  | end
  | 
  | rule "Routing Rule using XPATH less"
  |     when
  | 	t:Task(status == 2 )
  |       
  |     then
  | 
  |     	System.out.println("NORMAL");
  | 	destinations.add("normal");
  | 	
  | end
  | 
  | rule "Routing Rule using XPATH test"
  |     when
  | 	t:Task(status == 3)
  |       
  |     then
  |     	System.out.println("TEST");
  | 	destinations.add("test");
  | 	   
  | end
  | 

Iam sending a Task object with the status member defined to the queue but iam not able to find the  desired output.

How to go about it ?
