Hi Guys. So Thomas, I had a look at the new additions around the JAXBHandler interface and I think this will work for JBossESB. I was afraid that it might require the ESB user to get down and dirty with the JBossWS bean configs, but I see that the handler can be set on the Endpoint - for some reason I missed that in your earlier post - sorry :-) I'll be back if I run into any issues. Thanks for sorting this out for us guys :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058300#...
