Hello, Im working on a project to create a bussiness activity webservice using EJB3 and Jboss5.0GA wich has JbossWS implemented. I Used the example given on the Jboss website called XTS-demo. I tried to make a own implementation and stripped the BA to 1 participant wich calles a simple calculation function. So far so good actually. The problem is the BusinessActivityManagerFactory wich resides in the arjuna package of Jboss. Whenever i call the following static method | BusinessActivityManager activityManager = BusinessActivityManagerFactory.businessActivityManager(); | I get a null pointer exception. The factory never made an instance of businessActivityManager . What am i doing wrong? is there a failure in the arjuna package or something else? kind regards, Niels van Haren View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197069#...
