I am putting a solution to my problem just incase it might help some one else. I've found the reason for my problem was because I used jboss-4.0.4.CR2-installer.jar to install my jboss. I downloaded jboss and unzipped jboss manually. I then upgraded to jbossws-1.0.2 and deployed my webservices. I used my client to call the webservice and I received the reply with out any errors. I didn?t have to make any changes to my war file. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961602#...
