Bind exception

[eeh]

Hi,

I got bind exception (Jave.ent.BindE xception: Cannot assign requested
address: JVM_BIND) when the following statement is executed.

ss=new ServerSocket(0x 55,0,InetAddres s.getByName("19 2.168.0.8"));

The host 192.168.0.8 is on and can be pinged.

Could anyone tell me why?

When I change the stement to be

ss=new ServerSocket(0x 55);

no exception is thrown.

Thanks!

But is it the IP address of the machine that's running the code?? It
should be...

Not from the same computer, actually it is a network standalone device.

If your host doesn't have a network interface with that address, you
can't do it. A socket (Socket or Serversocket) can only bind to the
address of one of the host's network interfaces.

Specifying a portnumber alone works because the address defaults to
the wildcard address (0.0.0.0), which matches all of the host's
interfaces.

What are you trying to do?

The device does have network interface and the server socket is working

when no specified IP is given. Pinging to the device is successful.

Actually the device is a parallel ethernet converter.

OK, I get your meaning. The server socket cannot be applied to a IP
from a remote host.
