综合电子报表服务程序的研发及其在水利系统的应用

Study and development of service program of integrated electronic report system and its application in hydraulics system

利用J2EE技术和WebService技术开发能运行于多种平台的网上综合电子报表系统服务器端的报表服务程序。该服务为报表系统客户端查询程序提供Web服务,接收各种报表服务的命令请求,并根据请求命令的类型进行相应处理,生成反馈文件,然后把文件保存到反馈缓冲区中特定报表服务目录中供报表查询客户端程序提取。在数据库连接上采用数据库连接池技术,以提高数据库连接的效率和性能。并就其在水利行业合同管理系统中的应用进行了深入的探讨。

Service program of the electronic report system (ERS), which can successfully run on multiple operating systems, was developed with J2EE (Java 2 Enterprise Edition) and Web service technology in this thesis. It provides web services for report query clients of ERS, and receives all kinds of requests from clients.Then,it processes these requests and produces feedback files. At last, it preserves these files in specified report service folder of the feedback directory for client taking. Database connection pool technology was adopted to improve the efficiency and performance of database connection. Application of ERS in contract management system of hydraulics system was discussed.
