Check out the following project: - jbpm.3/designer/jpdl/org.jbpm.gd.jpdl.ui ?? - surely we have to check out more than this. There isn't even a build script in that directory. The entire designer project has to be checked out doesn't it, and the build.xml script in the designer/jpdl directory has to be run to produce the zipped up feature? anonymous wrote : 3. Start the Eclipse runtime workbench and you should be able to use the plug-in Sorry, but I don't understand. What do you mean by the "Eclipse runtime workbench"? I have run the build script mentioned above, and unzipped the feature into the eclipse-3.2 I installed, and run it successfully that way. Is that what you mean? Also, from your instructions, I still do not see how you are actually working on the source. Are you doing it in Eclipse? If so, how are you setting up the ui project in Eclipse?
