I guess I wasn't clear enough.
I didn't put them in all of those places at the same time. In subsequent
startups of jBoss I had them in only one of the places mentioned in my earlier
email.
Kevin's advice worked. The ejb (or at least the remote and home interfaces)
need to be in the system classpath (don't put them in WEB-INF/lib or
WEB-INB/classes). In other words add the jar or classes directory to your
classpath in the run.sh (or run.bat) file. I thought I had tried this before,
but it didn't work. Anyway, it *does* work now.
If you put your ejb in one of the WEB-INF places then Tomcat loads your remote
or home interface (via the AdaptiveClassLoader), but the proxy is loaded by
(I am assuming) jBoss (via the java.net.UrlClassLoader).
Anyway, thanks Kevin.
