Hi, Thanks for your concern, The problem with socketException got solved by putting INTERNET permission in manifest.xml file. But now i am encountering a new problem as follows i have created Serversocket as follows ServerSocket clientListenerSocket = new ServerSocket(); But i dont see port# being in listening state when i do netstat -a on windows XP machine.Strange part is its not generating any exception. because of this client is unable to connect to this port I guess host OS is not allowing to allocate these ports. i would like to know what could be the other reasons for this particular problem. and what is the procedure to find free ports on Windows XP machine.

Sal, Just figured I'd post this here since it might become relevant for you. If you come across the error: 12-01 18:27:52.175: WARN/System.err(764): java.net.UnknownHostException: Host is unresolved: www.strazzere.com:80 This exception was thrown whenever .connect() or .getOutputStream() where called. Obviously www.strazzere.com is just an example, but you might find that a known and resolvable host is getting the exception thrown, the trick is to restart the emulator. It seems to lose something if you change network connections or go in/come out of hibernation mode. Sorry if this seems off topic, but I wasn't able to find a solution to my problem yesterday so I figured I'd post this here!

Hi Martin, I am listening in my code on port# ie emulator, so what is relevence of port redirection in this scenario, for e.r if i do port redirection as follows add tcp:: , then to which port client has to send request wheather to or Thanks Suhail On Dec 3, 1:37 am, strazzere [EMAIL PROTECTED] wrote: Sal, Just figured I'd post this here since it might become relevant for you.
