I've just been thru this with some (partial) success. First step is to 
install the latest release (CVS) in /usr/local so that its available as an 
ALTERNATIVE to your trusted compiler. Write your Makefiles to use the 
version you'll install into /usr/local/bin. Installation/compiling is 
straightforward but compute intensive.  Just follow the instructions, 
especially the part that says to use separate build and source directories.

Then the following Makefile should get you started

BIN= \
     MyClass.o \
	... snip ...

CP=classes:... snip ...:rt.jar

.SUFFIXES:
.SUFFIXES: .java .o

%.o: %.java
   @echo Compiling $<
   @/usr/local/bin/gcj -c -O2 -o $@ -I/myjar.jar $<

all: $(BIN)

ctags:
   ctags -R .
