Simon, currently the designer is pretty much a moving target... The layout of my workspace is as follows: - jbpm.3/designer/jpdl/org.jbpm.gd.jpdl.feature - jbpm.3/designer/jpdl/org.jbpm.gd.jpdl.help - jbpm.3/designer/jpdl/org.jbpm.gd.jpdl.ui - jbpm.3/designer/jpdl/org.jbpm.gd.jpdl.ui.test There is *a lot* of dependencies on other Eclipse projects. The best thing to do is have a look at the build.properties file in the jbpm.3/designer/jpdl folder. To make the long story short, if you have WTP 1.5 and all its dependencies all should be okay. Hope this helps, don't hesitate to bug me for more info... Regards, Koen View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958015#...
