What is the purpose of stub and skeleton?

1 answers

Stub

The stub is an object, acts as a gateway for the client side. All the outgoing requests are routed through it. It resides at the client side and represents the remote object. When the caller invokes the method on the stub object, it does the following tasks:

  • It initiates a connection with remote Virtual Machine (JVM).
  • It writes and transmits (marshals) the parameters to the remote Virtual Machine (JVM).
  • It waits for the result.
  • It reads (unmarshals) the return value or exception.
  • It finally, returns the value to the caller.

Skeleton

The skeleton is an object, acts as a gateway for the server side object. All the incoming requests are routed through it. When the skeleton receives the incoming request, it does the following tasks:

  • It reads the parameter for the remote method.
  • It invokes the method on the actual remote object.
  • It writes and transmits (marshals) the result to the caller.
