Chris,
Many thanks for your reply!
From eclipse I exported the application as a runnable jar file -- I can execute it by "java -jar SQSServiceProcess.jar" on command line. In the jar file I can see all the .class files.
Does it have to be the jar files instead of the class files when packaging?
Where should I put SQSServiceProcess.jar? In folder \jbpm-5.1.0.Final-installer\jboss-5.1.0.GA\server\default\lib, or inside the war file \jbpm-5.1.0.Final-installer\jboss-5.1.0.GA\server\default\deploy\jbpm-gwt-console-server.war? I tried both places but neither worked.
Thanks,
Billy
