I have the following idl file,

valuetype LinkedList{

//some methods
long getData();
void setData(in long data);
.......................
};

exception MalFormed { };

interface Calculator
{
LinkedList add ( in LinkedList list, in long i) raises (MalFormed);
........................
}

How to register value factories on the client and server and let them
communicate valuetypes as LinkedList.

Any code example?
