That's probably the easiest. I guess the more "standard" way would be to
pull the stuff off the message directly instead of using the
MessageContextImpl wrapper thing, but the wrapper avoids a bunch of casts and
stuff.
You could do:
((Map<String, List<String>>)message.get(Message.PROTOCOL_HEADERS)
to get the map of all the protocol headers and process the cookie things
yourself. Probably not fun.
You could also to:
(HTTPServletRequest)message.get("HTTP.REQUEST")
to get the request object and grab the session and everything from there.
Not sure how valuable that is to you.
