Fwd: custom DatagramSocket and DatagramPacket

[Roger Abelenda]

I also need to make other classes in my implementation (apart of the
Datagrams) visible by any class when i'm using the "modifyed" jvm. I'm
meaning thath those classes can be imported without setting nothing
after compiling de jvm. I want to make them part of the standard
classpath. Suggestions?
