A couple of months ago one of the JBoss forum users suggested that notification messages sent by the jbossws ws-eventing engine should be validated against the underlying schema before the actual dispatch takes place (link). Heiko Braun opened a feature request issue on JIRA… and last week we submitted a patch for it.
If you’re interested in adding this feature and you’re running jbossws 1.0.4 GA, you can read about and download it here.
