1、tomcat版本Tomcat-5.0.12，jdk-1_5_0_13
2、ssl配置成功后，通过访问https://localhost:8443/ 可以看到tomcat主页
3、将cas-server-webapp-3.1.1.war放到webapps下更名为cas.war
4、访问https://localhost:8443/cas报错，重新走流程试了好多次都是报错，错误如下：
HTTP Status 500 -

求高手指导。。。
这个和tomcat的版本有关，你用的是5.0版本，那还是servlet2.3，jsp1.2的版本，
cas的jsp页面用了jsp2.0的语法导致
其实tomcat你可以不用换，找到cas跳转的jsp页面，修改相应位置以符合tomcat5.0版本的规范就好了嘛
