Hi, I have an ear appliaction including JBPM and Seam. It's pretty simple at the moment. It basically works, only problem I have is when I have JBoss running the application and I build a new ear and replace the current one with it (redeploy), JBPM cannot start properly because it cannot locate jbpm.conf.xml file. It looks like Seam is actually starting JBPM in this case, could it be a classloading problem? It is fixed by restarting JBoss, which is a bit annoying, especially during development. Anyone can help?
