[jboss-user] [JBoss jBPM] - Error while deploying Processdefinition thru a servlet

[jbpmIndia]

Hi 
I am using 'jbpm 3.1.3' on 'JBOSS AS 4.0.5.GA'
I am executing following code in a servlet


  | JbpmConfiguration jbpmconfig = JbpmConfiguration.parseXmlString(
  | 	 "<jbpm-configuration>" +
  | 				      
  | 	 // A jbpm-context mechanism separates the jbpm core
  | 	 // engine from the services that jbpm uses from
  | 	 // the environment.
  | 				      
  | 	 " <jbpm-context>" +
  | 	 " <service name='persistence' " +
  | 	 " factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />" +
  | 	 " </jbpm-context>" +
  | 	 "<jbpm-context>" +
  | 	    "<service name='persistence'>" +
  | 	       "<factory>" +
  | 	          "<bean class='org.jbpm.persistence.db.DbPersistenceServiceFactory'>" +
  | 	             "<field name='isTransactionEnabled'>" +"<false/>" +"</field>" +
  | 	          "</bean>" +
  | 	       "</factory>" +
  | 	    "</service>" +
  | 	    "<service name='tx' factory='org.jbpm.tx.TxServiceFactory' />" +
  | 	    "<service name='message' factory='org.jbpm.msg.db.DbMessageServiceFactory' />" +
  | 	    "<service name='scheduler' factory='org.jbpm.scheduler.db.DbSchedulerServiceFactory' />" +
  | 	    "<service name='logging' factory='org.jbpm.logging.db.DbLoggingServiceFactory' />" +
  | 	    "<service name='authentication' factory='org.jbpm.security.authentication.DefaultAuthenticationServiceFactory' />" +
  | 	  "</jbpm-context>" +
  | 
  | 				      
  | 	 // Also all the resource files that are used by jbpm are
  | 	 // referenced from the jbpm.cfg.xml
  | 				      
  | 	 " <string name='resource.hibernate.cfg.xml' " +
  | 	 " value='hibernate.cfg.xml' />" +
  | 	 " <string name='resource.business.calendar' " +
  | 	 " value='org/jbpm/calendar/jbpm.business.calendar.properties' />" +
  | 	 " <string name='resource.default.modules' " +
  | 	 " value='org/jbpm/graph/def/jbpm.default.modules.properties' />" +
  | 	 " <string name='resource.converter' " +
  | 	 " value='org/jbpm/db/hibernate/jbpm.converter.properties' />" +
  | 	 " <string name='resource.action.types' " +
  | 	 " value='org/jbpm/graph/action/action.types.xml' />" +
  | 	 " <string name='resource.node.types' " +
  | 	 " value='org/jbpm/graph/node/node.types.xml' />" +
  | 	 " <string name='resource.varmapping' " +
  | 	 " value='org/jbpm/context/exe/jbpm.varmapping.xml' />" +
  | 	 "</jbpm-configuration>"
  | 	 );
  | 	 	 JbpmContext jbpmContext = jbpmconfig.createJbpmContext();
  | 		 ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("processes/WorkFlowTest/processdefinition.xml");
  | 	 		 jbpmContext.deployProcessDefinition(processDefinition);

In have kept 'processdefinition.xml' under processes/WorkFlowTest under WEB-INF
and I am getting the following error.

I feel it's crashing at the line
JbpmContext jbpmContext = jbpmconfig.createJbpmContext();
Pls tell what am I missing ?? It's urgent..
thanks
