custom packages

[Roger Abelenda]

Hi there, me again :-). I'm implementing an DatagramSocket and a
datagramPacket and i want to subsitute the ones of the jvm with this
ones. If you know: where may i put my code and what shall i do to make
it compile when i compile the jvm?, and , what changes i need to do to
plug it into the original code to make the jvm call my classes when
somebody calls the original ones?. I thought to change the
classloader.c  and the resolve.c. Any other options? thanks.
