Dear Keith

It would of course be better to resolve the multiple definitions 
(shouldn't be too hard, just remove them from the jaxen jar), but you 
can also do it with the gcc flag as you have tried. What you're looking 
for is
-Wl,--allow-multiple-definition
It's a linker option, so "-Wl" is needed so that gcc/gcj knows it has to 
pass the "--allow-multiple-definition" to the linker.


Hope that helps
Marco
