Hi,

I have 3 java classes ClassA, ClassB, ClassC.

ClassA{
	int idA;
	String stringA;
	public ClassA(){}
	public ClassA(int idA,String stringA){
		this.idA=idA;
		this.stringA=stringA;
	}
	public int getidA(){
		return idA;
	}
	public String getstringA(){
		return stringA;
	}
}

ClassB{
	int idB;
	String stringB;
	public ClassB(){}
	public ClassB(int idB,String stringB){
		this.idB=idB;
		this.stringB=stringB;
	}
	public int getidB(){
		return idB;
	}
	public String getstringB(){
		return stringB;
	}
}

ClassC{
	int idC,idB;
	String stringC;
	public ClassC(){}
	public ClassB(int idB,int idC,String stringC){
		this.idC=idC;
		this.stringC=stringC;
	}
	public int getidC(){
		return idC;
	}
	public String getstringC(){
		return stringC;
	}
}

I want ClassA in replicated mode and B & C in partitioned mode. ClassC is
related to ClassB. The id of ClassB is present in ClassC (acting like a
foreign key). Say, I have 3 nodes, 30 ClassA objects, 30 ClassB objects and
30 ClassC objects. They are distributed in nodes like below;

Node 1 => ClassA->30, ClassB->10,ClassC->8
Node 2 => ClassA->30, ClassB->5,ClassC->3
Node 3 => ClassA->30, ClassB->15,ClassC->19

Objects of ClassC related to ClassB should present in same node. I know that
there is some mechanism AffinityKey, but I don't know how to implement this.
Could somebody tell me how to do this?

Thanks in advance..
