Java APIs

I'm playing ard with some website which use ajax

without ajax, page will be loaded synchronously, request then response.

I could then use HttpURLConnection java class to write a simple application to mimic the operation of website, send request to server, get back html code, extract info and then send request again, so on and so forth

With XMLHttpRequest involved, is there anyway to do the similar above?
(ultimate goal is to write a pure java code to automate some webbrowser's task)

would appreciate any suggestion
Thanks

Oh btw, i wasn't sure this is the appropriate subforum to post this question. If it isn't. Please advise
