Greenstone can do most of this, but is mainly C++ and Perl. We don't really
have good libraries either -- a lot is done with command-line Perl scripts
which call other executables. I think all the functionality is there, but it
isn't very accessible, and certainly not as a Java library.

Sorry I couldn't be more helpful,

All the best,

Michael
