Socket Problem

[Pro79]

hi to All,
I am facing some problem regarding the socket programming in java .
I made a connection to a printer through the socket and i am sending some request to the printer it`s work fine
The socket is keep a live infinite time

I am storing the sockets in hashmap , as i have connected more than printer to the system .

Now the problem is thats if some body switch off of the printer then again on the printer , my socket doesn`t seems to be working . As it was using the old socket

Can any body tell is there a way to check whether a socket is disconnected (means if some body switch off the printer)

Looking for the good reply !!!!!!!!!!!!!

Have you ever tried using the javadoc or manual for Java ?

http://java.sun.com/j2se/1.4.2/docs/api/java/net/Socket.html

If you had consulted this, then you would see that there are five methods of interest :

isBound()
isClosed()
isConnected()
isOutputShutdown()
isInputShutdown()

In any case, should you not be creating a new socket each time someone wants to print something, rather than keeping an open TCP/IP Socket open ?
