There seems to be an issue running processes outside of the container when they
contain sub-process. The following code is a simple test that has one process
with a contained node that is a sub-process. This code produces the following
error:
Exception in thread "main" org.jbpm.JbpmException: can't create a process
instance when processDefinition is null
| package com.mincom.ellipse.test;
|
| import org.jbpm.graph.def.ProcessDefinition;
| import org.jbpm.graph.exe.ProcessInstance;
|
| public class SubProcessTest {
|
| public static void main(String[] args) {
| ProcessDefinition superDef =
ProcessDefinition.parseXmlString("<?xml version=\"1.0\"
encoding=\"UTF-8\"?><process-definition xmlns=\"\"

| ProcessInstance superInst = new ProcessInstance(superDef);
| ProcessInstance subInst = new ProcessInstance(subDef);
|
| while(!superInst.hasEnded()) {
| superInst.signal();
| }
| }
| }

I've done some reading about this and it seems that the JbpmContext must be
initialised and any sub process definitions loaded before the super process is
called and signalled. However what do you do if you are unit testing the
process or indeed running processes that are not long running or deployed to
the database?
