setting time out

[Sagar kanchi]

Hi,

I need to set timeout for Connecting to the net.
Actucally I am doing a project using Tomcat as web server. In one of my modules my program need to connect to a website 'n' download the file.
Sometimes, for this to be happened its taking a lot of time. But I don't want my app to take much time. I want to set the maximum time to connect and download the file as 30 sec. How can I do this. I am using Windows Professional as OS 'n' Tomcat as my WebServer.
Can anybody help.........

You can set a timeout on the connection with URL or the Apache HttpClient HttpURLConnection equivalent. But I don't think either let you set a timeout on the whole connect, send request, get response, disconnect operation.

I'm trying something right now that puts the http code in a runnable and the main thread looks like this:

Downloader dl = new Downloader();
dl.start();
dl.wait(TIMEOUT);
if(!dl.isDone())
{
   interrupt dl
   throw some timeout exception
}
result = dl.getResult();

There is a little more detail around synchronizing and threading, but that's the main idea. You can probably guess how Downloader notifies the main thread that it's done (if it finishes at all) and how it might use the interrupted() method to stop what it's doing. Does that look like it would help?
