11.4. Defining External Rules for Content-Based Routing with XPath

Procedure 11.2. Task

1. Open the jboss-esb.xml file and set the cbrAlias property to XPath.
2. Define the routing expressions in a .properties file. Make sure the property keys correlate with the destination names and that the property values are the XPath expressions for routing to this destination.
3. Define the routing rules in the route-to configurations via the container destinations property. The destination-name attribute will refer to the XPath rule key as defined in the external .properties file as shown:

   <action class="org.jboss.soa.esb.actions.ContentBasedRouter" name="ContentBasedRouter">
      <property name="cbrAlias" value="XPath"/>
      <property name="ruleSet" value="/rules/xpath-rules.properties"/>
      <property name="ruleReload" value="true"/>
      <property name="destinations">
          <route-to destination-name="blue"  service-category="BlueTeam"  service-name="GoBlue" />
          <route-to destination-name="red"   service-category="RedTeam"   service-name="GoRed" />
          <route-to destination-name="green" service-category="GreenTeam" service-name="GoGreen" />
      </property>
   </action>
