Hi ,

     I got the solution.

Steps:

     1. While restarting application, re-registers listeners to the task client.

     2. In my case starting process was like this:

..

ProcessInstance pi = ksession.createProcessInstance("com.sample.bpmn", null);

ksession.startProcessInstance(pi.getId());

..

     for such multiple command execution need to use transaction(see :http://docs.jboss.org/jbpm/v5.2/userguide/ch07.html#d0e2914)

// create the entity manager factory and register it in the environment

EntityManagerFactory emf =

    Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );

Environment env = KnowledgeBaseFactory.newEnvironment();

env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );

env.set( EnvironmentName.TRANSACTION_MANAGER,

         TransactionManagerServices.getTransactionManager() );


// create a new knowledge session that uses JPA to store the runtime state

StatefulKnowledgeSession ksession =

    JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );


// start the transaction

UserTransaction ut =

  (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" );

ut.begin();


// perform multiple commands inside one transaction

ksession.insert( new Person( "John Doe" ) );

ksession.startProcess( "MyProcess" );


// commit the transaction

ut.commit();

Now problem is solved . for more info see discussion at https://community.jboss.org/thread/195660

Thanks for ur help...
