Hi, the link Ronald provided contains a section 'Additional Notes for jBPM 3.2.1/jBPM 3.2.2' with two possible ways to get the right libraries in the web-console on JBoss 4.2.x: * checkout the sources from cvs and use the provided ant task OR * manually include the listed jars in the web application Either one of the two approaches should work. Which one did you try? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120016#...
