8 a.m.
Hello,
I'm implementing a class that is both a EJB3 stateless session bean and also exposes
itself as a JAX-WS Web service. Below you can see relevant excerpt from the code.
When I want to access the WSDL document from a Web browser I get an NPE, see below. When I
remove the EJBContext variable declaration including the @Resource annotiation the
exception does not appear.
I'm using JBoss 4.2.3GA and jbossws-cxf-3.0.4.GA.
It seems to me that it is related to CXF but appears only for classes that are both EJBs
and JAX-WS Web services. Am I right or did I missed something? Should I try with
jbossws-native or jbossws-metro again or would they fail as well?
Regards,
Thorsten
