如何配置eclispe和Tomcat，可以联合开发jsp？

[huaxianz]

我按照网上的一些教程配置了elcipse

但是当比如运行http://localhost:8080/TestJsp/TJsp.jsp时，出现500 error page
好像提示JAVA_HOME配置问题
我试过在系统变量里设过，也在elcipse里class variable里设过。都不启作用。

HTTP Status 500 -

应该把jdk的lib中的tools.jar放在classPath里~~~

安装tomcat 插件
在http://www.sysdeo.com/eclipse/tomcatPlugin.html下载合适的plugin，将zip包解压到eclipse里面的plugin文件夹下，然后再将包内的DevLoader.zip解压到%TOMCAT_HOME%/server/classes里面
重新打开eclipse，在eclipse中 window－>Workbench->Preferences －>Tomcat 设置Tomcat home
之后就可以在eclipse中创建tomcat项目，还可以在里面启动停止tomcat服务器
