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.
