ejb application server

I am looking into ejb and wondering is there any ejb application server that will run on linux? One with Open Source is prefered, but a commercial one that has free demo version available is ok too. Thanks for the help! Walter --

File or class transfer over tcpip

I am in the mist of developing an RMI Update utility for clients. Like most updaters they would download a small 30k(+-) java application that would talk to an RMI server and decide what files (.class) the client needed. It works like a charm but, the typical but word my classes when used by the
