NamingException / SocketException during AppMod lookup

Question

Hi,
below there is an Exception i received while try to connect to the AppModule,
deployed as "AppModule Session Bean", to an OC4J 9.0.2. At the End you see my
Sourcecode which produces the Exception.
Does anyone have an Idea whats going wrong with my sourcecode?
Regards Mirko

} Try..
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(amName);
ApplicationModule appModd = home.create();
If you have exported methods then you should be able to cast the
appmodule returned by home.create() to you're appmodule interface. This is the interface generated in the common subpackage.
