Installing and running Jbpm5 demo setup...

[fabianpc]

Hi all,

I have installed and executed jbpm5 using ant project jBPM.install. When I try http://localhost:8080/designer/editor. I get a message: could not load process designer.

Server log show: ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/designer].[ProfileServiceServlet]] Allocate exception for servlet ProfileServiceServlet
java.lang.UnsupportedClassVersionError: Bad version number in .class file

Which is the problem?

This is usually the case when you are trying to run the application with a Java version that is less recent than the one the designer was built with.  The designer currently requires Java6 to run, so make sure your application server is running using Java6.  Let us know if this helps.

Hi Kris.

Finally, I read the file: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/readme.txt, and this indicates that it requires Java 6. But when I make the deployment of the file: designer-1.0.0.026-SNAPSHOT.war, the editor does not run correctly. I try http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/designer.war file, then the editor is run.

Greetings.

Fabian.

Fabian,

Yes, the designer war that works for you is an older version that should work for all browsers.  The only downside is that that version is still using an older version of the BPMN2 specification.  Version 026 is more recent but only works on Chrome (some strange javascript loading issue).  We're currently updating to the latest version of the designer, so we will be updating that soon with a newer version using the latest BPMN2 specification and supporting multiple browsers again.
