Hi Santanu

Thanks for your respnse.

When i use this statement in my code, i am getting the below exception.

org.jbpm.api.JbpmException: no environment to get org.hibernate.Session
	at org.jbpm.pvm.internal.env.Environment.getFromCurrent(Environment.java:196)
	at org.jbpm.pvm.internal.env.Environment.getFromCurrent(Environment.java:189)

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
	at java.lang.reflect.Method.invoke(Method.java:585)

Then changed the statment from
ProcessInstanceQuery query = new ProcessInstanceQueryImpl(); to
ProcessInstanceQueryImpl lProcessInstanceQuery  = (ProcessInstanceQueryImpl) WorkflowUtil.getExecutionService().createProcessInstanceQuery();

I am not sure, is it the correct way of getting ProcessInstanceQuery?

Also once the ProcessInstance is started, i want to get the current activity name from process instance. Is there any method avaialble in ProcessInstance?

Please suggest me.
