[jbpm-users] [JBoss jBPM] - Hibernate error while deploying process in a web application

[vignesh57]

i am trying to implement jBPM in a J2EE Web application. I am doing three things.
1) Deploy a process
2) Start an instance.
3) Show a list of available instances.

My Environment:
jBPM      : 3.2.X
jBoss     : 4.2.X
Database: MySQL

Below is the piece of code embedded in a method inside a DAO class. This is invoked from the servlet when the user hits the Deploy button in the jsp page.

  | public String redeployProcess(String processName) {
  | 		System.out.println("->public String redeployProcess(String processName)");
  | 		System.out.println("----->Creating jBPM Configuration....");
  | 		JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
  | 		try {
  | 			System.out.println("----->Parsing process definition....");
  | 			ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource(processName);
  | 			System.out.println("----->Deploying Process definition....");
  | 			jbpmContext.deployProcessDefinition(processDefinition);
  | 			System.out.println("----->Deploy Successful....");
  | 			return "Process " + processDefinition.getName() + " redeployed.";
  | 		} finally {
  | 			System.out.println("----->Closing jBPM Context....");
  | 			jbpmContext.close();
  | 		}
  | 	}
  | 

And this is the exception i got....

Works well in Tomcat !

I ran this application in Tomcat and it worked perfectly alright. Initially i faced some problems but with the help of existing posts, i made it work well.....

Why not in jBoss ?

If it works well in Tomcat, then it must work in jBoss too. And also i dont know Hibernate. I can see that it is trying to get a Session through SessionFactoryImpl.getCurrentSession() and the effort fails. 
But how is it able to get one in Tomcat ?

Any help here would be deeply appreciated. if I am missing out to provide any info, please do ask me.
