Java representation in Haskell

[Paulo Sequeira]

Hi,

A friend is considering to start a project of building a generator of
certain particular (pieces of) programs. The code generated is most likely
to be Java.

Anyone knows of a module that provides data structures and functions for
representing and manipulating Java source code, so we don't have to start
from scratch? It would be wonderful if the module also includes some
"out-of-the-box" pretty-printing facilities for the representation.

Thanks in advance.
