Hi Richard, as you may know JBoss Developer Studio is a commercial version of the IDE. They release new versions integrating the new plugins twice a year, as far as I know. Probably the next release includes the jBPM5 plugins, but jBPM5 was just released in february. You probably can try to install the latest snapshots of the community project and see if it works: https://hudson.jboss.org/hudson/job/jBPM5/lastSuccessfulBuild/artifact/target/
Simply download and unzip http://community.jboss.org/servlet/JiveServlet/download/15922-6-25925/jbpm-5.0.0-eclipse-all.zip in your eclipse root directory and restart eclipse. That should do it. We're looking at integrating it into JBDS.
I unzipped the file into the ..\studio\plugins folder and started up the studio. I had hoped to be able to restart studio and see the option to create a new jBPM5 project. No luck with that. I guess for now I will just work with the Eclipse that got installed via the standard installation procedure.
I guess I just need to play with this a little more to learn more about how it all gets set up and used. The documentation is a bit weak here but hopefully will mature over time. Perhaps someone will document what they learn in this area :-)
