I remember having had a similar issue (with a completely different product) where this was the case. Roland: I tried different approaches to solve this problem (with more or less the same result so far): 1. Parse a XML file included in my JAR 2. Parse a string 3. First deploy the process, then deploy the application, then invoking the process. BTW, there is no other process deployed, only different versions of the same process. Is this what you were talking about?. Regards. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3991129#...
