7. Conclusion

The Remote Procedure Call (RPC) or its equivalent in the object world (the Remote Method Call RMI) are structuring models used to describe the interaction between two software components that communicate by exchanging messages. One of the two components, the client, initiates the dialogue and generally remains blocked while the other component, the server, processes the request. This model is undoubtedly the most widespread for implementing distributed applications. The main reason for this success is that the remote procedure call strives to reproduce for a distributed environment the conditions of a local procedure call (both in terms of the programming model and the execution model).

This programming model is now widely used to access remote services, and it's logical that it can be used directly to build distributed applications using Web protocols. To this...
