Thanks for the reply - I've been doing some digging into where the NPE happens, and while I'm sure it has something to do with my Embedded setup (it works just fine when I point a full Tomcat at the war file using a Context file), there are other things I need to look at, which are nothing to do with Embedding - I'll start another thread on CometProcessor, and maybe come back to this once I'm sure that comet isn't to blame.
Thanks, Joe.
