[JBoss-user] [JBoss.NET] - Nullointer exception when accessing Web Service

[aubade_78 <nu...@jb...>]

Hi All, 
        I am using jboss 3.2.6 and I have deployed a WS through a .wsr file which contains the web-service.xml in the meta-inf directory. I also have the class which i want to expose as the WS in the appropriate package in the same jar. I checked the service through the axis servlet and i could get the wsdl file. I also generated stub code using the same. 

Now when i try to access the webservice using a client i got a NULL POINTER exception. I did search on the forum and it seems there was a bug. So I also replaced the patched jboss-net.jar and tried again but got the following error 

10:28:31,756 ERROR [Engine] StandardWrapperValve[JBossAxisServlet]: Servlet.serv
