I'm trying to deploy a Web Service taking and returning an org.wc3.Element argument. I can't find any examples on google, all of them teach you how to make a Web Service taking a String argument, and this is fairly easy and yes, it does work. Can anyone provide an example, or, at least, tell me if there are any things one need to have in mind when he wants to create WS with Element as argument? I'm using JBoss 5.1 and I deploy my WS as a WAR package. I can't change version of JBoss. Btw. I have successfully deployed simple WS with String argument.
