After reading through the article posted, there seems to be a missing link:
Download the latest snapshot of jsf-console-tomcat.war, the web console based on JSF. Extract the contents to the tomcat-<version>/webapps/jbpm-console/ directory.
When I click on the war file, it redirect me to the following website, but there is no war file to download.
https://repository.jboss.org/nexus/content/repositories/snapshots/org/jbpm/jbpm3/jsf-console-tomcat/
Does anybody know where I can find the war file referenced?
Thanks.
