Hprose is a High Performance Remote Object Service Engine.
It is a modern, lightweight, cross-language, cross-platform, object-oriented, high performance, remote dynamic communication middleware. It is not only easy to use, but powerful. You just need a little time to learn, then you can use it to easily construct cross language cross platform distributed application system.
Hprose supports many programming languages, for example:
* AAuto Quicker
* ActionScript
* ASP
* C++
* Dart
* Delphi/Free Pascal
* dotNET(C#, Visual Basic...)
* Golang
* Java
* JavaScript
* Node.js
* Objective-C
* Perl
* PHP
* Python
* Ruby
* ...
Through Hprose, You can conveniently and efficiently intercommunicate between those programming languages.
This project is the implementation of Hprose for Java.
