[jboss-user] [JBoss jBPM] - Re: Exception while executing SubProcess
Thank u Martin.I could able to solve that exception now.
but now iam getting NullPointerException.
Below is the modified code and Exception .
| JbpmConfiguration jbpmConfiguration
=JbpmConfiguration.parseResource("hibernate.cfg");
| JbpmContext jbpmContext=jbpmConfiguration.createJbpmContext();
| try{
| // parsing sub process
| ProcessDefinition subProcessDefinition =
ProcessDefinition.parseXmlResource("ChildProcess/processdefinition.xml");
| jbpmContext.deployProcessDefinition(subProcessDefinition);
| System.out.println("subproceess Deployed ");
| ProcessDefinition processDefinition =
ProcessDefinition.parseXmlResource("MainProcess/processdefinition.xml");
| jbpmContext.deployProcessDefinition(processDefinition);
| System.out.println("Main proceess deployed");
|
| ProcessInstance processInstance =
processDefinition.createProcessInstance();
| System.out.println(" a: "+
processInstance.getRootToken().getNode().getName());
| processInstance.signal();
| System.out.println(" b: "+
processInstance.getRootToken().getNode().getName());
| System.out.println("going to Process State now");
| processInstance.signal();
| System.out.println(" c: "+
processInstance.getRootToken().getNode().getName());
| System.out.println("reached to process State Now");
|
|
| System.out.println(" : "+
processInstance.getRootToken().getNode().getName());
|
| processInstance.signal();// i expect , signal to end node of main process here. but
i got the below exception.
| System.out.println(" d: "+
processInstance.getRootToken().getNode().getName());
|
| }
| catch(Exception e)
| {e.printStackTrace();}
| finally{
| jbpmContext.close();
| }
|
And the exception is
| java.lang.NullPointerException
