Sorry for my late response, but I was on vacation. Thank you for the ideas. Yes, the Error occur also with JbossWS 2.0.1. I´ve taken the TestSample called 'webservice' of the JbossWS-native-2.0.1GA package and modified it by adding a simple TestBean with the @EJB annotation inside of the 'EJB3Bean01.java'. See the listing below: [EJB3Bean01.java] | ..... | public class EJB3Bean01 implements EJB3RemoteInterface | { | @EJB | private TestBeanIntf testBean; | | @WebMethod | public String echo(String input) | { | return testBean.printString(); | } | } [TestBean.java] @Stateless | @LocalBinding(jndiBinding = "TestBeanIntf") | public class TestBean implements TestBeanIntf { | | public String printString(){ | return "Hello Peter!!"; | } | } This works very well, only if all classes are in the same package, if you move the TestBean in another package, the Error I described in the startposting occur. So, I think this is the problem. Unfortunately, I have more than ten packages with several beans. Should I create a new Jira Issue and add the whole zipped eclipse project as an attachment?
