Can I get an answer on this please ?
Strangely enough, I am not getting any answer to this question. Maybe it is stupid or badly worded.
Let me put it another way then : what is the most recent version of JBossWS that I can use on a J2EE 1.4 compliant application server, such as JBoss 4 ?
All I want to do is use SOAP 1.2 over http, document-style messages, and WS-Security with X.509 certificates.
I'm not surprised your not getting an answer, it is a simple straighforward question. I would suggest switch to Glassfish. This will meet all your requirements and if you run into problems you'll get better support.
