The system uses tomcats . 2 and resin2 . 0 as jsp engine at the same time at one machine so as to test the feasibility and stability by deploying different port to different jsp engine to provide virtual multi - server environment . this can improve the using rate of single server and provides effective solutions to burdened server at the time of responding to the request of client 系统采用了tomcat3 . 2与resin2 . 0同时作为jsp引擎(同时还作为webserver和servlet容器) ，在单服务器下通过端口的不同设置构造了虚拟的多服务器环境，试验了单机系统里多jsp引擎( web服务器、 servlet容器)同时运行的可行性与稳定性，提高了网络服务器的利用率，也为单一服务器高负荷运行时有效产生客户端响应提供了行之有效的解决方案。
