Thanks dear Tihomir, I had already figured this out.
Thanks to your only and 2 days late reply ;) , I had time and opportunity to learn a few app server tricks. exploded war deployment and stuff...
but there are more questions coming out each time I learn something new. for example some people say just deploy your jars to app server's classpath located at server/{profile}/lib, while some other say you should use exploded war method and put jars in WEB-INF/lib directory for exploded jbpm-gwt-console-server.war. Can u please tell what's the real difference?
Thanks Tihomir
