This is a VERY good idea!
I would like to cast a vote in favour of a Java/XML standard for doing invoking
EJBs via XML, so that all EJB containers/servers would provide the capability in
a compatible way. I would envisage that security, transaction and session
context information would all be encoded in the XML so that the XML request is
truely transport-independent.
