Fantastic! Great Thanks, that was it (war MANIFEST.MF + client.jar)! Jboss
is cool!
My jboss_jetty servlet now talks with EJB. After three days of my strugle,
your latest instructions made it a breeze.
I am puzzled with just couple of more points:
- Bean class(es) does not have to be included in client.jar, which is great,
as logic can be changed without its redeployment at servlet container.
However, I am curious why BOTH remote _and_ HOME interface(s) are required
in client.jar, not only remote one?! If only remote interface(s) is
included, servlet
cannot be initiated (404 http error).
- interestInstance.getInterestInfo() returns exact custom string, as
specified in bean.
However, why servlet EJB call: interestInstance.getClass().getName() returns
(always)
"$Proxy3" as an EJB class name, not "Interest" ?!
Thanks again and best regards. Miomir

The key is the MANIFEST.MF file of the .war file.
Your .war file needs classes from an other package (the one with your
beans or better the one with only the remote stuff for your beans). So
you create a MANIFEST.MF file for your war file (if you dont have
already) and you add a line like this:
Class-Path: ./myBeanRemoteStuff.jar
where myBeanRemoteStuff.jar is the name of the jar file containing the
needed classes _and_ is contained in the root directory of your .ear
file.
(unjar the tomcat-test.ear/tomcat-test.war and have a look at the
MANIFEST.MF file there!)
Then recreate your .ear file and deploy.
You should get a log line like this:
...
[J2EE Deployer] Added ./myBeanRemoteStuff.jar to common
classpath
...
