1  Game Development / Networking & Multiplayer / Re: Can't make an applet to connect to socket server. on: 2010-11-11 15:39:44
Ammm when I run the server on ubuntu 10.10 I see the server runing on tcp v6
netstat -tapn | grep 4444:
1  
tcp6       0      0 :::4444                 :::*                    LISTEN      28087/java

maybe this is a problem :?
Hmm if I run it on the same machine it works... however on a windows machine in work and on my netbook (all firefox) it does not start. No firewalls on both PCs

3  Game Development / Networking & Multiplayer / Can't make an applet to connect to socket server. on: 2010-11-11 10:36:00
Hello,
I'm trying to get a simple server (application) / client (applet) to work. My problem is that it all works in eclipse... but when I open it in firefox I get a black rectangle... I made a jar package and signed it ... ( I get the alert that my app's digital signature cannot be verified and Do I want to run it ). Huh
