From your comments to the jBPM3 on Tomcat article, you certainly noticed it was incomplete. When I got to the authentication realm part, I could not keep going as the Tomcat built-in realms do not match the jBPM identity model. I did some prototype work in this area and got the jBPM3 Console to work on Tomcat. Please take another look at the finished article.
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.
Does anybody know where I can find the war file referenced?
