Communication between client and server

I need to run a server side program such that it will run in background and wait for the client message. and at client side i need to send a message to server. and at server depending on the message i got from the client i need to run a piece of code.
I don't know much of socket programming i will be thankful if any one can post a sample code or else any link to the sample code.

thanking you in advance,

I understand that you are looking for code directly... but I'd recommend you try doing it by yourself.. here are the hints.

1) ServerSocket is a java class which can create a socket (IP/Port combination) in the server, and keep listening for incoming packets.
2) Socket is another java class which can communicate to any other socket or serversocket.

As is so often the case, the Sun Java Tutorial has examples of exactly that. Start reading at http://java.sun.com/docs/books/tutorial/networking/sockets/index.html

Dear Thammudu ,

you need to follow these steps to see success

1) I think you don't know much of socket programming you will be thankful if any one can post a sample code or else any link to the sample code in formus.
2)you need to run a server side program such that it will run in background like THREADS and wait for the client message.
3)At client side you need to send a message to server through protocals either TCP or UDP/WI-FI
4) At server depending on the message you got from the client you need to run a piece of code in background process.

If the method explained in the link I posted doesn't work for you for some reason, then you should tell us *why* that is. It is the standard approach, after all.
