Thanks for this post.
I copied my workitemhandler jar to JBOSS_HOME\server\default\deploy\jbpm-gwt-console-server.war\WEB-INF\lib & JBOSS_HOME\server\default\lib and restarted the jboss server. But when i hit the process definations url from jbpm-console process (http://localhost:8080/gwt-console-server/rs/process/definitions) ClassNotFoundException is thrown.
Please help me to find the solution. Thanks in advance.
