基于J2EE框架和XML技术的电子政务系统研究

采用基于XML标准的数据交换方式，基于J2EE框架和XML技术构建了电子政务系统，解决政府不同部门之间异构数据交换技术，基于语义Web技术实现了电子政务数据资源共享，采用了MVC设计模式来实施电子政务系统。分析了如何把J2EE和XML无缝的结合到电子政务系统平台开发应用中去，介绍了系统开发过程中关键的、先进的技术。

Study on the Network System of Urban Environment Monitoring Based on GPRS

XML data exchange methods based on J2EE framework and XML technology were used to build an e-government system to exchange the heterogeneous data between different government departments, based on the realization of Semantic Web Technology, e-government data were shared by using MVC design patterns to implement e-government systems.Analysis is conducted on the combination of J2EE and XML in the application of the e-government system,the critical and advanced technologies are introduced.
