USB设备的Java Web应用系统设计

设计了一个JavaWeb应用系统，通过服务器对某嵌入式设备的USB接口进行数据收集、处理，实现了生产过程监控的网络化。服务器端采用JSP＋JavaBeans技术，使用第三方开发包，编写具有USB通信功能的JayaBeans程序，隐藏了通常Java程序通过JNI调用本地其它语言程序的过程．从根本上减少了系统开发与维护的复杂程度。使用这种技术允许用户快速而方便地把网络功能加在没有联网的设备上，而不用负担重新设计设备的花费。

Design of Java Web Application System of USB Device

A Java Web application system is designed,which collects data from the USB interface of some embedded device,and processes data through server.The system realizes the networking of controlling production process.The server adopts JSP + JavaBeans technology,uses the third party developing kit,writes JavaBeans program with USB communication function,and hides the usual course that Java program transfers local program of other language through JNI,so as to reduce the complexity of system development and system maintenance radically.Using this kind of technology,the users are allowed to add the network function on the device not networked fast and easily,needn't afford the cost of redesigning the device.
