Re: jBPM 5.1 without HumanTask Service

created by Massimiliano Izzo in jBPM - View the full discussion

I already removed the start.human task from the build.xml, and I received the error I put in the post #1.

 

I am using the jBPM 5.1 version, and there is no jbpm-human-task-war.war in the deploy folder.

I can see a jbpm-human-task-5.1.0.Final.jar in the WEB-INF/lib directory of the jbpm-gwt-console-server.war, but if I remove this jar, I get the following error

 

 

HTTP 500:

note The full stack trace of the root cause is available in the JBoss Web/2.1.10 logs.

I would like to understand which is the configuration file that instructs the jbpm console to look for the human task service.
