Sorry, but I can't do this quickly -- I am very pushed for the next few days. I will try to replicate it if I have time later on. As I said at the beginning, I have no such problems with Glassfish, using JAX-WS2.1 and JAXB2.1 but instead I encountered a connection pooling problem which I couldn't solve, hence my interest in JBoss AS (and I'm anyway using Hibernate). Never mind, it was worth a try.. Thanks for your interest. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4093940#...
