RPC (Remote Procedure Call) is the Ajax workhorse of GWT.
GWT offers an easy-to-use RPC mechanism that makes it easy for the client-side code and the server-side code to communicate Java objects (serialized objects) back and forth using standard HTTP.

Remote procedure call (RPC) is a communication technique used in distributed client-server architecture which allows a program to cause a subroutine to be executed remotely on another computer. That said, the remote subroutine is written like a local one, avoiding the details of the interaction with the network. Note : Remote Method Invocation (RMI) can be considered as refering to a particular implementation of RPC in Java. |
In server mode, GWT provides automatic serialization of the request and automatic deserialization of the response from the server.
