Sriramkumar,
my assumption would be that the UnknownHostException is being caused
by Java version issues. "java.lang.IncompatibleClassChangeError" means
that something that your client is attempting to send over the wire
(the org.jnp package is for remote name lookups) is not recognized by
the server, but it would certainly help to have all of those logs,
both the ones that Chris has mentioned as well as the server log:
OMERO_SERVER_DIR/jboss-4.2.3.GA/server/default/log/server.log
Thanks for helping us track this down.
