Hi,

this is my emulation demo link: http://img7.imageshack.us/img7/5281/emulation.gif , code link: http://pastebin.ca/1484952 . This demo is working fine on emulation but when i put these jar files in my mobile phone and try to achieve the same peer 2 peer connection my client application is not able to find server.
what i think is my server is not connecting to the INTERNET using GPRS since its not asking me any access points.
but my client side is working fine and i have given you my server-side code link
Please do check line no. 46 of this server code where scn = (ServerSocketConnection)Connector.open("socket://:5000");
its a TCP Server using socket connection.

Plus am pasting my code here
