"jbpm5.3 error with deployed process accessed from jbpm-console" To view the discussion, visit: https://community.jboss.org/message/750683#750683 -------------------------------------------------------------- Hi, I have a demo installation of jbpm 5.3 and use the default embadded h2 database. I a created a simple process that includes only one node - domain specific custom node that only prints to console. The whole process works fine under eclipse. I'm trying to access the process from jbpm console, so I modified CustomWorkItemHandlers.conf in the jbpm-gwt-console-server.war, to relate my custom node to appropriate handler and included the handler in the jbpm-gwt-console-server.war classpath and it seems the handler class is visible because I'm not getting classNotFoundException (conserning my handler class) in the server log any more. I included my bpmn so it's visible under jbpm-console. Now, when I log in jbpm-console I can see my process in the processes list, along with the demo Evaluation process. However when I clik on my process I'm getting: ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/gwt-console-server].[Resteasy]] (http-localhost-127.0.0.1-8080-5)
