Ok! My installation was, from the Jbpm-4.0 (10th of July stable version) folder: cd jboss ant -Djboss.version=5.1.0.GA demo.setup press ok. Database is embedded and autoconfigured. Example deployment is automatic. The installative gave no error. But the taskform doesn't work. How can I do to make it work? Thanks.
