I am running into the similar problems, however I am currently executing the jBPMs standalone. In that case how do we specify the anonymous wrote : sub-process My mail processdefinition looks something like this - anonymous wrote : <process-state name="invokeAutomation"> | <sub-process name="AutomationService"/> | | </process-state> The problem is I get a jBPM exception anonymous wrote : can't create a process instance when processDefinition is null. How exactly do I bind the sub process to the main definition? I tried doing this as well - <sub-process name="AutomationService" binding = "late"/> the above does not conform to xsd but there is some code in ProcessState that lets you do binding later. But again how exactly do I bind. I also wanted to write my own resolver, as I understand the configured name is jbpm.sub.process.resolver, do I have to make this configuration in jbpm.cfg.xml. I am confused since I dont find this configuration made in the default configuration. If someone can help, it would be great.
