Hi Dario, What I did was: 1.- Download bpel-extension from http://www.jboss.com/products/jbpm/downloads. 2.-Unzip in my file system. A folder called jbpm-bpel-1.1.Beta3 was created. 3.-Then you only had to follow the user guide. In the configuration of hibernate and jbpm, i don't modify anything, the default values works well. To generate the service and then deploy it in the jboss server, you should to intall ant. Agus View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024568#...
