logging into a Yahoo group

hi:

here is what I want to do:

-->i want my Java client code to log into a Yahoo internet group that I have set up. I dont want this logging to happen via a browser. This group contains some XML files.

-->I then want to to be able to download those XML files to the client computer.

I have tried using HttpClient (a Jakarta project) but it seems that logging into Yahoo is problematic (understandably so) with all the re-directs that take place so as to prevent programmatic log in.

I am new to Java and that surely does not help as well. Are there some Java classes that perhaps might help me? Also, how can I simulate this logging in process without being rejected by Yahoo?

Much thanks.
