This application use JSP for user input, use servlet for user request parsing, manufacture data through JDBC technology on the database, use Apache Tomcat as the middle-ware server. We use the Visual C++ to build the back-end compiling-judge system,and use JNI technology to join the divide between Java and C plus plus. But the front-end web system and the back-end auto-compiling system are not coupled, they are parallel running. The back-end system also use JDBC to communicate with the database, manufacturing the datas and going on its tasks. The application schemed in the paper is passed testing on Windows Server 2003 Service Pack 2. Keywords Program Contest, ACM/ICPC, J2EE, Java 目录 摘要 I
