Deserialize remote object to the narrowest accessible class

In shared.jar I have:


abstract class MyParent {

}
abstract class MyClass {
MyParent getFoo();
}


server.jar contains

abstract class MyChild extends MyParent {

}
abstract class MyClassConcrete {
MyParent getFoo() {return new MyChild();}
}

client.jar:

MyParent foo = myClass.getFoo();

If all 3 jars are in one classloader everything works well.

But client and server are in different JVMs while:

• JVM-1 contains: server.jar, shared.jar
• JVM-2 contains: client.jar, shared.jar

Client makes call to server. Server returns MyConcreteClass and Java fails to deserialize it (ClassNotFoundException).

What I wanna do:

• Server serializes class and sends data and set of class's ancestors
• Client finds the narrowest ancestor it may deserialize.

And everything is ok: we have instance of MyParent on the client and that is what we need.

I can't believe there is no such engines. Do you know one? I am sure remote call should be as similar to local calls as possible.

Thanks.
