Deploy a process containing service task in Activit Explorer

[rajendrarahul]

Hi ,
I am new to Activiti. Trying to deploy a process with service task in it. It gets deployed successfully , but while I start the Process , I get a pop up with message 'null' . I placed the Jar in the 'lib' directory of activity explorer.Deployed the .bpmn20.xml file using Kermit user in usual way.My '.bmpn20.xml'  file content is

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

Putting the jar on the classpath is normally all you need to do.

There should be a stacktrace in the Tomcat logs. Could you paste that one here?
