Hi Marco,

That certainly does help, I'm a little further down the road and am battling 
with the following error now.

Exception in thread "main" java.lang.NoClassDefFoundError: 
java.text.DecimalFormat
   at gnu.xml.transform.Stylesheet.initDefaultDecimalFormat(win32.exe)

I've asked a few questions on the java-gcc mailing list, they've been very 
helpful and have suggested the following:

#copy libgcj to a working dir (could be in a different location than 
/usr/lib/ for you)
mkdir -p /tmp/mess_with_libgcj
cd /tmp/mess_with_libgcj
cp /usr/lib/libgcj.a .

#extract all the object from this library
ar x libgcj.a

#make a lib with only the properties objects
ar rvcs libgcj_properties.a *properties*.o
#do the (sometimes superfluous) blessing of the lib
ranlib libgcj_properties.a

#copy the lib to the system lib dir
cp libgcj_properties.a /usr/lib/

#goto your source project and this time link-in those properties objects 
with --whole-archive, this forces the linker to include them even if they 
aren't statically referenced
cd <your source build-tree>
*gcj* -o <your 
prog> -Wl,--whole-archive -lgcj_properties -Wl,--no-whole-archive -static-libgcj 
 --main=<your main>



Now, I've tried add the flags 
(-Wl,--whole-archive -lgcj_properties -Wl,--no-whole-archive) to the Custom 
GCJ flags section. However I can't seem to add them in the correct order. 
JNC seems to re-order them for me and it ends up:
-Wl,--whole-archive -Wl,--no-whole-archive -lgcj_properties

Is this a restriction or am I missing something?
