Well I definitely have my remote and home interfaces in both the war and
the ejb-jar files along with any user defined exceptions that my ejbs
throw. I did hit a ClassNotFoundException on a home interface once but
that was because I had been playing around with the Interceptors loaded
by the EmbeddedTomcatService.
The way I finally figured out what was going on was to strip down my war
file to its barest minimum and add pieces back in until I hit where the
exception occurred. You might want to put together a test war with just
one beans interfaces and write a servlet to try looking up the home.
Sorry I can't offer any more help
