Hi all,
*I successfully starts the +Human Task Service of jBPM5.1+ in JBoss by modifing the Persistence.xml: :)*

a*nd by making JTA data-source as under:*
<datasources>
<xa-datasource>
<jndi-name>testDS1</jndi-name>

<user-name>jbpm5</user-name>
<password>lupin</password>
</xa-datasource>
</datasources>
By these modifications and placing the necessary files, I able to start the human task service via JBoss :
*Now I want my +jbpm task+ run using this service as under:*
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
WSHumanTaskHandler objWSHuman= new WSHumanTaskHandler();
objWSHuman.setConnection("127.0.0.1", 9123);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",objWSHuman);
// start a new process instance
Map<String, Object> params = new HashMap<String, Object>();
params.put("employee", "rajan");
params.put("reason", "Yearly performance evaluation");
ksession.startProcess("com.sample.evaluation", params);
System.out.println("Thats itt..");
*But on the JBoss console it gives the following error*: :(
