做mondrian例子时，报错，我根据流程一步步做的（初学者），就是数据库不一样，也不知道对不对，不过报错的地方是copy来的，怎么回事啊，在线等，先谢了，我没分了 不好意思

Invalid TLD resource path /WEB-INF/jpivot/jpivot-tags.tld,自定义标签文件的路径不正确，，tld是jsp标签配置的定义，里面规定了jsp自定义标签的的格式，属性，实现类等内容。

java.lang.noclassdeffounderror: javax/servlet/servletrequest 这个类没有找到。 可能的原因为: 1、没有对应的javax.servlet.jar 2、jar包版本不对,导致容器没有加载
