xml rpc是使用http协议做为传输协议的rpc机制，使用xml文本的方式传输命令和数据。一个rpc系统，必然包括2个部分：1.rpc client，用来向rpc server调用方法，并接收方法的返回数据；2.rpc server,用于响应rpc client的请求，执行方法，并回送方法执行结果。RPC是Remote Procedure Call的缩写，翻译成中文就是远程过程调用，是一种在本地的机器上调用远端机器上的一个过程（方法）的技术，这个过程也被大家称为“分布式计算”，是为了提高各个分立机器的“互操作性”而发明出来的技术。

在工程中一定要导入两个jar包，jar包分别是：

xmlrpc-2.0.1.jar

commons-codec-1.3.jar-xml rpc rpc using the http protocol as a transport protocol mechanisms, the use of xml text transmit commands and data. An rpc system, necessarily includes two portions: 1.rpc client, calling the method used to rpc server and receive the return data　2.rpc server, rpc client in response to a request to perform a method, and a method to perform loopback results. RPC is a Remote Procedure Call acronym, translated into Chinese is a remote procedure call is a call to a procedure on a remote machine (method) technology on the local machine, this process is commonly known as "distributed computing" , is to improve the technology of each discrete machine "interoperability" and invented.

In the project must import two jar package, jar package are:

xmlrpc-2.0.1.jar

commons-codec-1.3.jar
