I'm trying to deploy a war file that contains all the libraries required. One of libs happens to be jbpm-jpdl.jar. When the file is included in with the other libs, jboss will not deploy the war, if the file is copied to the lib directory (default/lib) then the deploy works fine. has anyone any clues as to why this is happening? for reference the exception that gets thrown is : java.lang.NoClassDefFoundError: org/jbpm/taskmgmt/exe/TaskInstance thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4132758#...
