Hello, Thanks for your advice but I still don't know exactly what to do. I still don't know how to use jbpm designer as a plugin for eclipse. I can't use the "Preferences" Menu and I can't use the "update manager" because I'm "offline" :) Who could give me very simple and accurate explanation (I'm a beginner) ? Thanks in advance Marie View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140210#...
