我安装JBUILDER2006,我启动TOMCAT后,http://localhost:8080/admin/为何打不开?请指教
我安装好了JBUILDER2006,然后在JBuilder2006\thirdparty\jakarta-tomcat-5.5.9目录下执行startup.bat,//localhost:8080是可以打开tomcat页面,但是http://localhost:8080/admin/提示如下错误,
Tomcat's administration web application is no longer installed by default. Download and install the "admin" package to use it.
不知道是还需要安装什么
