How to set timeout on client socket connection?

Question

I am trying to set the timeout of a connection on the client socket in java. I have set a default connect timeout to 2000, i.e:

this.socket.connect(this.soc         


        

Answer 1

You can even try for :

Socket client=new Socket();   
client.connect(new InetSocketAddress(hostip,port_num),connection_time_out); 

Answer 2

To put the whole thing together:

Socket socket = new Socket();
// This limits the time allowed to establish a connection in the case
// that the connection is refused or server doesn't exist.
socket.connect(new InetSocketAddress(host, port), timeout);
// This stops the request from dragging on after connection succeeds.
socket.setSoTimeout(timeout);

Answer 3

What you show is a timeout for the connection, this will timeout if it cannot connect within a certain time.

Your question implies you want a timeout for when you are already connected and send a request, you want to timeout if there is no response within a certain amount of time.

Presuming you mean the latter, then you need to timeout the socket.read() which can be done by setting SO_TIMEOUT with the Socket.setSoTimeout(int timeout) method. This will throw an exception if the read takes longer than the number of milliseconds specified. For example:

this.socket.setSoTimeout(timeOut);

An alternative method is to do the read in a thread, and then wait on the thread with a timeout and close the socket if it timesout.
