I used to think so (it *seems* to be allowed if you use a well established 
interface). However I was told by one of the guys at the FSF that this is a 
no *unless* it conforms to an established, widely implementable interface. ie 
I could write a GPLed servlet, GPLed ejb etc and run them in non-GPL 
containers. However I have got different answers depending on who I asked - 
so I am not sure ;) I would recomend pleeing with the writers of GPL 
library/tool to see if they would make it LGPL, Mozilla, BSD or virtually any 
other license ;) 

 
Cheers,

Pete
