I have installed jbpm-jpdl-3.2.6.SP1 (pointed to Jboss 4.2.3) and installed the jbpm-jpdl-designer-site.zip shipped with it on Eclipse 3.4.2. I Created a test process project. But it is showing error : Project 'ProcessTest' is missing required library: 'C:\jbpm-3.2.6.SP1\lib\activation.jar' . This jar is not present in jbpm lib directory. How to fix this? where is this activation.jar available? Am I using stable versions? do I need to install any dependent jars? Thanks, indra.
