jBPM4JSF is a Facelets tag library for integrating any JSF+Facelets application with jBPM.
Since the source is now part of the complete jBPM code, it is available as subproject 'jbpm.3/jbpm4jsf'. For more details about how to get the jBPM sources, please have a look at this wiki.
You can also browse the sources using fisheye:
Once you have checked out the complete sources, go to the 'jbpm.3/jbpm4jsf' subdirectory and type "ant" to build the jsf components. The JAR will be deposited into the target/ directory.
JIRA issue JBPM-567 is where the tag TODO list exists.
