BTW, Fred, I'm reading "SOA Security" by publisher Manning right now, it says
WSS4J is for Axis 1.x while Rampart is for Axis 2.0.  That doesn't seem
correct--isn't WSS4J used with both Axis1 and Axis2?  Or is it just that
Rampart uses WSS4J internally?  I'm trying to get a feel for how up-to-date
WSS4J is.

As for the caching of the nonces, don't Axis 1 and Axis2 handle that
themselves (because WSS4J can't do it itself right now, perhaps)?  You want
to make sure that if Client X made a request with nonce = 4, no more
requests of X with that nonce value within the timeout period are made, so
that offhand would appear to be something that the web service provider can
handle.  Then again, maybe this caching can be handled by WSS4J--less work
for us.

As for WS-SecureConversation, AFAICT it is just a generalization of
WS-Security[1]--the tokens (of whatever type, Kerberos, SAML, UsernameToken,
or whatever) are not continually regenerated/resent for each reply/request.
It's primarily a performance issue--WS-SC makes things faster.  So I'm not
exactly clear when you write "I think the right way to tackle that is to
integrate with Kerberos and the GSS-API"--I think, whatever you do
WS-SC-wise, would need to be generalized for *all* token profiles, not just
Kerberos.  But I'm hardly the most knowledgable on this stuff.

Regards,
Glen
