I started working on the CE installation guide: http://cwiki.apache.org/confluence/display/ESME/CE+Installation+Guide
It is definitely a work in progress. The last time I tried it I didn't get it to work - if I remember correctly based on datasource problems. I'll try it tomorrow with the in-memory datbase to see if I can get the deplyoment to work. If anyone else wants to give it a shot or improve my version, I'd really appreciate it.
