hi...
I use ObjectInputStre am and ObjectOutputStr eam to transfer file from client to server. It works fine when i test it in the same pc. But when test using two pcs (one pc for client and one pc for server), the program just blocked at this statement ===> oin = new ObjectInputStre am(conn.getInpu tStream());

why would this happen? Is the firewall will caused tz problem?
Anyone knows the problem??
thanks for...
