Hey!! Thank you very much for the best description about WS in java i ever read. The fact was , i was wrong about the AS (i'm using 4.05). So everything with WSTools was ok. The problem was in Java. The JDK 1.6.0 was used. And there's a bug reported in JIRA. Sadly but trully i missed it. I changed to 1.5.0_09 and everything is working flawlesly. JSR181 looks really great. We decided to go for JBossAS solution. Allthough there's a possible conflict in future (jboss+wstools+hibernate) vs (jdk1.6.0 + [JPA + jaxws), we believe solution. OpenSource is great if used with caution ;). thank you.. i will be in touch with our progres. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4007661#...
