Integration with C

Hi Andrew,
I've read over the gcj documentation in try to find a logical way to 
register a collection of function pointers. The only structure that I 
can find is the gnu.gcj.RawData class which can contain anything but 
need to be cast to the correct type explicitely. Is this a way to do 
what I need, or am I overlooking something? It would be great to see 
some examples of this, do you know if there are some available?
Thanks for the help,
Geert
