Yes, you must use a sane JDK as well and that can be tricky but Ubuntu has
some nice utilities that make this a breeze. Perhaps this message  can
help, it looks very relevant. You should be able to use Sun's JDK 1.5...

If you follow the instructions in  and use 'update-java-alternatives' as
described, ant should 'do the right thing (tm)'.

Yes, when using gcj 4.2.x, you need to use -Wno-write-strings. See the Linux
64 section in the PyLucene Makefile for an example. As a matter of fact, other
than changing LIBDIR_NAME, you should be able to use that section as is,
making sure the paths match your system, of course.
