Hi TJ,
The various timeouts are, as they sound, timeouts for specific operations. For example when connecting to a server (HttpClient.setConnectionTimeout()) it is the time HttpClient will wait until the connection is established (the socket is opened). In the case you are seeing the problem is not timeout, it's that the server specifically rejects the connection. It may very well be that the server under high load rejects connections. The only recourse in this case is to retry the method.
HttpClient.setTimeout() sets the socket SO_TIMEOUT. This is the timeout for an individual read() operation on a socket. Please see the java.net.Socket docs for a little more detail on this.

Hi Mike,
The URL is correct. The GetMethod is executed within a for loop, and this exception occured only in some loops...
Well, maybe it is the server that cannot cope up the speed, and delaying the loop might help in this case.
Anyway, what is the HttpClient.setTimeout() really means? Why it is not applicable in this case where the server could be down/slow in returning the response?

Hi TJ,
The host/port you are connecting to appears to not be listening. Please double check the URL you're connecting to and give it a try in a browser to make sure it's actually there.

I encounter ConnectException: Connection refused: connect
eventhough I set the timeout to 0 (infinite timeout?), what could be the problem?
My program:
MultiThreadedHttpConnectionManager connManager = new MultiThreadedHttpConnectionManager();
client = new HttpClient(connManager);
client.setTimeout(0);
the exception:
