timeout

[Ariffin Ahmad]

i made a client to make a socket connection to some server.
this client will send some parameter and will waiting for some reponse after that.
the problem is, how can i put a timeout to that client, so that the client don't have to wait forever for the response...

Is Socket.setSoTimeout() what you're looking for? With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.io.InterruptedIOException is raised, though the Socket is still valid.

thanx mate...
one more problem....
how about, while the client waiting for servlet response, ie: waiting in read() statement, how can i interrupt the read(), so that i don't have to wait any response from the server to in order to end my process...

You can't, except by either (a) setting a timeout as indicated above, or (b) close()ing the Socket from another thread. The latter is an undocumented, but widely used trick. Of course after (b) your socket will be unusuable.

To do what you are talking about you need to have a separate Thread running which monitors how long it takes to get the InputStream back from the socket connection. If the time required to get the InputStream exceeds the timeout you have defined then you would want to throw some sort of exception.
There is a class called com.jscape.inet.util.TimedSocket which will do this for you in the iNet Factory distribution available at http://www.jscape.com

Hi, guys.
Here is my question related to socket creation timeout. We want
to control process of socket creation and if socket hasn't been
created in timeout period just continue with the program flow.
Here I've wrote some simple program and it's shows me different
results on different platforms:

import java.net.*;
import java.util.Date;
public class SocketTest
{
public static void main(String [] args)
{
Date date1, date2;
date1 = new Date();
try {
Socket s = new Socket("10.0.10.146", 1000);
} catch (Exception ex)
{
ex.printStackTrace();
}
date2 = new Date();
System.out.println("it's took us " + (date2.getTime() -
date1.getTime()) + " millisecs.");
}
}

Here I'm using "10.0.10.146" as IP address of non-exist computer
When I run it on Windows 2000 - it gives me ~ 21.5 second. But
Sun Solaris - 219.5 second (x10 from Windows time).
So my question: Is any way to control that (beside creating
thread which will wait for n seconds and if socket not exists
yet will send some kind of exception)?
Any answer appriciated.
Alex.
