tomcat 5.4中，errhandler.jsp可以显示，
若选择 java可看到 You got that right! 信息
若选择其它则ie中提示：
无法显示网页
您要访问的网页有问题，无法显示。
求解决办法！
------解决方法--------------------------------------------------------
改成runtimeexception试试
------解决方法--------------------------------------------------------
我记得exception接受的是runtimeexception.
如果你把
throw new Exception("You chose the wrong language!");
改成 int a=10/0;
或者throw new RuntimeException("You chose the wrong language!");
