I dont think i understand what you're asking. You'll have to open a ServerSocket for each port you want to listen to. It being blocking IO has little to do with it.

hi,

i mean lets say the first line of code is making socketserver to listen on port 25

and the second line is making another socketserver to listen on port 143, but if no connection cam to the first socketserver "25" the execution will never reach the second line "socketserver listening on port 143" this is called blocking but i want this part to be non blocking sockets can you help me any body?

thanks again :0

You will certainly have to have two accepting threads, one per ServerSocket, and they will have to spawn a new thread per accepted socket too.

There is a Sockets tutorial in the JDK, see the Guide to Features/Networking.
