Thank you for the reply.

Actually here is the scenerio..

Here, when node1 throws the exception, it should traverse through transition error.

Here is the processdefinition.xml

<?xml version="1.0" encoding="UTF-8"?>

<process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="VitWork">

          <start-state name="Start">

                    <transition to="node1"></transition>

          </start-state>

          <node name="node1" async="true">

                    <event type="node-leave">

                              <action class="com.sample.action.MessageActionHandler1"></action>

                    </event>

                    <transition to="node2" name="ok"></transition>

                    <transition to="Error Handling" name="error"></transition>

          </node>

          <node name="node2" async="true">

                    <event type="node-leave">

                              <action class="com.sample.action.MessageActionHandler2"></action>

                    </event>

                    <transition to="Approve"></transition>

          </node>

          <task-node name="Approve">

                    <task name="Approve"></task>

                    <transition to="end"></transition>

          </task-node>

          <task-node name="Error Handling">

                    <task name="Error Handling"></task>

                    <exception-handler exception-class="java.lang.Exception">

                              <action class="com.sample.exceptionHandler.ExceptionHandler"></action>

                    </exception-handler>

                    <transition to="end-state1"></transition>

          </task-node>

          <end-state name="end"></end-state>

          <end-state name="end-state1"></end-state>

</process-definition>

Here is the MessageActionHandler1.java

package com.sample.action;

import org.jbpm.graph.def.ActionHandler;

import org.jbpm.graph.exe.ExecutionContext;

public class MessageActionHandler1 implements ActionHandler {

          private static final long serialVersionUID = 1L;

          public void execute(ExecutionContext context) throws Exception {

                    System.out.println("Thread 1 going to Sleep for 15 seconds...");

                    throw new Exception("Dummy Exception");

          }

}
