hi Carlos:
Are you saying that the
$ORACLE_HOME/javavm/demo/examples/ejb/session/clientserverserver sample
failed to run in your installation? Did any of the EJB samples work for
you? This is important, because we *KNOW* that these samples work for a
typical install. If they dont work, there is something wrong - it could be
your installation, your machine, your network, but there is definately
something wrong.
Running anything else or trying to deploy your own code in this
installation is probably not a good idea without solving this problem first.

john.
