thanks again, i configured all libraries like de user guide describes, but as you said "thats right its not the ideal procedure" but if works its just fine. the only thing thats its not clear for me is that i configured the jbpm libraries as the user guide says, but when i create the java project the jbpm libraries not apears on the list to include. im evaluating returning to jbpm3....but bpmn notation of jbpm4 its great!
