Hi a All,

I use these line to get a url.
url = new URL(Url);
BufferedReader in = new BufferedReader(new
InputStreamReader(url.openStream()));

but in some cases I got connection timed out error and program exit. As
I want to get lots of URLs this will cause problem. Is there any way
that I detect connectino timed out and in that case what is the best
thing to do? resending URL?

Thanks a lot.

Hi,
I guess it depends on how you program flows, but when I have needed to
connect to multiple URL's, I have put each attempt in a separate
thread. That way, you will be able to continue processing whilst
waiting for a url to come in.

If you want to control the connection timeout period for a URL, i.e.
set it, URL has a method setConnectTimeout(int millis). See:

http://java.sun.com/j2se/1.5.0/docs/api/java/net/URLConnection.html#setConnectTi
meout(int)

You have to be careful about firing off too many url requests at once,
as you can really jam up your bandwidth, so the number of concurrent
threads you run will be found through trial and error.

Hope that helps

Nikk
