Is there a way to annotate a POJO JSR181 style and be able to get to an attachment from the SOAP request? Don't really see much in the documentation that speaks to doing it with JSR-181 style SOAP-RPC style requests (or any other method for that matter).
Is it possible?
No, isn't possible.
Please note that is out of the jsr-181 spec, not a choice of jboss. AFAIK.
