Processing image tag in task.jsp not working

[davidsan1001]

If I comment out the line below in the task.jsp, everything works fine. Otherwise the whole page breaks.

<jbpm:processimage task="${taskBean.taskInstanceId}"/>

Here is the the full error message from the browser. Another question, at the bottom it mentions "The full stack trace of the root cause is available in the Apache Tomcat/5.5.9 logs." I'm running JBoss-4.0.1, where is this log located?

javax.servlet.ServletException: org.apache.jasper.JasperException

Fixed by moving tasks so they aren't right under each other.

You can find it in {jboss.home.dir}/server/{server.config}/log/server.log.

I only get a boot.log file not server.log. Is there another setting so it outputs this file as well?

depends on the configuration of log4j.xml. The default JBoss does this, if you take the jbpm instance, created by the ant files or the starterkit, you probably don't. The solution you describe (re-layouting the process image) is the right one. It is a bug I think in the processing of the node locations. Please file a Jira issue for this.

For me, all nodes go on top of eachother if in the GPD I switch from a xsd in the header to a non-xsd version.

This problem can be solved by placing two jar file into the webapp:jbpm/WEB-INF/lib. The two jar file is:dom4j-1.6.jar,jaxen-1.1-beta-4.jar. These two jar file can be found in the project lib/hibernate.

That's will be ok.

Thanks Ronald, Alex, Alain. I'll integrate all of your suggestions.

Now that I have the basics, on to more interesting workflows! :-)

How do you file a JIRA issue? Can you post a link?
