Hi.,
Iam trying to executing the below program in which ProcessState node is used.
<process-definition
| xmlns="" name="MainProcess">
| <start-state name="start">
| <transition name="" to="state1"></transition>
| </start-state>
| <state name="state1">
| <transition name="" to="process1"></transition>
| </state>
| <end-state name="end1"></end-state>
| <process-state name="process1">
| <sub-process name="ChildProcess"></sub-process>
| <transition name="" to="end1"></transition>
| </process-state>
| </process-definition>
And the childProcess is
| <process-definition
| xmlns="" name="ChildProcess">
| <start-state name="start">
| <transition name=""
to="ChildProcessState"></transition>
| </start-state>
| <state name="ChildProcessState">
| <event type="node-enter">
| <action name="Action"
class="com.iton.handlers.ChildProcessAction"></action>
| </event>
| <transition name="" to="end1"></transition>
| </state>
| <end-state name="end1"></end-state>
| </process-definition>
|
The Program which iam trying to Execute is
| JbpmConfiguration jbpmConfiguration
=JbpmConfiguration.parseResource("hibernate.cfg");
| JbpmContext jbpmContext=jbpmConfiguration.createJbpmContext();
| try{
| // parsing sub process
| ProcessDefinition subProcessDefinition =
ProcessDefinition.parseXmlResource("ChildProcess/processdefinition.xml");
| System.out.println("Entered into Subproceess");
| jbpmContext.deployProcessDefinition(subProcessDefinition);
| System.out.println("subproceess Deployed ");
| ProcessDefinition processDefinition =
ProcessDefinition.parseXmlResource("MainProcess/processdefinition.xml");
| System.out.println("Entered into Main Process");
| jbpmContext.deployProcessDefinition(processDefinition);
| System.out.println("Main proceess deployed");
|
| ProcessInstance subProcessInstance =
subProcessDefinition.createProcessInstance();
| jbpmContext.save(subProcessInstance);
| System.out.println("subproceess saved ");
| //parsing parent process
| ProcessInstance processInstance = processDefinition.createProcessInstance();
| jbpmContext.save(processInstance);
| System.out.println("Main Process Saved");
|
| 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();
| }
| catch(Exception e)
| {e.printStackTrace();}
| finally{
| jbpmContext.close();
| }
|
But I found the following Exception while executing the above code.

And I found that exceptiom is araised when it entered in to subprocess and the statements
in childprocess action are printed on console.Also processdefinition and processinstances

Please Some one Help me to solve this Problem.
Thank you.
