remote ejb call trapped in the lookup in linux server

I'm using glassfish 3.1.1 with an application client container called via java web start. My program is not working , it remain glued in the lookup() and never pass it .

        Context c = new InitialContext()
        geo = (GeoBeanRemote) c.lookup("java:global/server_side/server-ejb/GeoBean");
        System.out.println("end lookup");

I ha开发者_运维知识库ve already tested this in a windows server and it worked perfelcty but now , in the production server (ubuntu 11.04) it doesn't . How can i fix this ?

Thanks.

It sounds like you might be having some routing issues. I suggest verifying your RMI port is open. The default is 3700.
