OData is Microsoft's repackaging of its Astoria (now WCF Data Services) RESTful query/update protocol. If I want to use Java to create an OData compatible data source, how do I do that? Similarly, if I want to consume an OData data source from Java, how do I do that?

class B extends A { void F() { System.out.println("b"); }}
public class X {
public static void main(String[] args) {
A objA = new B();
objA.F();
}
}
Here, F() is being invoked dynamically, isn't it?
