I need help me, please!!!
hi, you can download and use the jboss eclipse ide, GPD is included. if you don't want to give up your own copy of eclipse, you can just use the GPD of jboss eclipse ide for the process definition, while web project can still be created and developed in your own eclipse.
to install a GPD as an eclipse plug-in is sometimes ..., i tried and gave up.
On your existing project, add : new ->Other ->JBOSS jBPM -> process definition
that should work
