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.
