我也发现了这样的问题
我使用startup.bat将Tomcat服务起来之后，完全没有问题
但是，如果使用Windows的Apache Tomcat服务将Tomcat起来之后，
在输入http://localhost:8080后就出现了和楼主一样的问题。
具体出错信息如下：

个人初步估计是环境变量的设置有问题
但是在我将JAVA_HOME,TOMCAT_HOME,classpath
甚至CATALINA_HOME,CATALINA_BASE等环境变量设置之后，
仍然没有解决这个问题。

希望各位道友共同探讨这个问题，

是你的tomcat的配置有问题,找不到class文件.

Tomcat不需要怎么设置吧，只需要指定jive相应目录即可。
而且当使用startup.bat开始Tomcat服务时，是没有这个错误的。
另外，如果是类没有找到，出错信息不应该是NullPointerException，
而是ClassNotFoundException。
所以偶不太同意楼上的观点，
希望再听听楼上的解释。
