Hi,


I try to use "isClosed" and "isConnected" but I got this error message...
"Method isClosed() not found in java.net.Socket"

Any idea what's wrong???

Also, I would like to know what's the different between "isBind" and "isConnect"??

isClosed method is from jdk 1.4.
Probably you are using a jdk less than 1.4.

isConnected is supported by all sockets
isBound is not be supported by all sockets
see the documentation of  bind (SocketAddress bindpoint)
          throws IOException

another system (JDK 1.3) to detect if socket is closed is to try to send/receive something. If an exception raised up, then the socket is closed.
