I haven't used 5.x but 6.0.14 does seem (I'm still testing) more stable than 6.0.16, though that’s probably not a good thing for the progress of Tomcat. > Ouch.

I'd love to be able to tell you more about it, all I really know is it’s a GATE application that's dealing with semantics, this is the problem we have, no one has ever used Gate to do what were doing and subsequently this service is a first for Tomcat so it’s a big case of trial and error at the moment and just to throw more spanners the gate developers are using JRocket. > If you do everything during the request, I suspect that sessions are not > necessary at all.

All the processing is done in the request and returned straight away, so your right :) Sessions are probably not necessary so that’s another line of testing.
