Java and using http webservice

[Eric]

I have a webservice that I need to use via an http call (get). I'm not
really sure hot to start. I have written servlets before, but never used a
webservice.

I make an send an http get to the webservice, and it returns some xml to me.
what classes should I use to facilitate this communication? what classes
does java provide for 'parsing' out the xml data?


Any direct help or pointing in the right direction is greatly appreciated.
Thank you in advance!
