any LWP::UserAgent equivalent in java && a java regex question

Hi All

I have found Perl's LWP::UserAgent and related packages useful. Does
java have any thing
equivalent i.e. that won't make me do encoding when I want to do an
http POST? I am a newbie
to java. Also, is there anything like java CPAN ?

Also, in perl, if I do /some pattern (some other pattern)/ I get "some
other pattern" in $1. I found
out that () have different meanings in Java. The only to get $1 in
Java is to write more lines.

Thanks in advance
