Thanks for the help guys. Turns out it was because I was using the jbossws that was installed with jboss-4.0.5.GA, which i believe is version 1.0.3. I guess jaxb bindings were not supported until a later version, because I installed 1.2.1.GA and everything worked as expected. However, I have a new question. My web service seems to be bound to http://localhost/MyBeanClassNameService/MyBeanClassName. Is there anyway to change that? I tried the name attribute of the @Stateless and @WebService annotations to no avail. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045880#...
