Hi Felix,
you might need this in jbpm.cfg.xml:
also maybe your SpeaddWorkFlow.StartWorkFlow() method needs a @Transactional annotation?
and finally you can try to do whatever you do in line 245 of SpeaddWorkFlow.java within a command like described by HuiSheng in this thread:
processEngine.execute(new Command() {
public Object execute(Environment env) {
// do something.
return null;
}
});
