How to change/mask ip address with Eclipse


this is a bit tricky as question, what I'm trying to do is basically
change my IP address inside my Eclipse application.
The reason is because I'm grabbing some content from web pages
automatically using jsoup and parsing links like a crawler, but some
website I crawl just block me after 3 request saying "you requested too
much specific pages for today, pay for more or wait 24h", so I change my
identity using TOR and I can grab (manually) 3 more pages.
I'm searching for something that will help me to grab those datas
automatically from a Java application. Now I'm using jsoup library but I
can use everything that let me just change my ip, for example using a
proxy or using VIDALIA/TOR api to get every 3 request a new identity as
application.
Do anyone have advices about this task? It's not very common but I think
it can help a lot of people.
PS: That's an idea, I think that IPV6 addresses are filtered as IPV4, so
as I can easly switch and request IPV6 addresses, probably I can solve
using IPV6, but I still don't know some library or some software that let
me use a proxy and change IP when I want inside my Java App.
Thanks a lot!
