将工程路径下的WebRoot下的WEB-INF下的lib里的jsp-api-2.0.jar,servlet-api-2.4.jar删除就OK 了,应该是工程里自带的这两个文件和TOMCAT里的文件冲突导致的

[tohmin]

也许是JSP页面那个方法调用有问题。

这种异常应该有好多人都遇到过的，好多时候都是页面的问题，比如非法运用一些表达式，或者没有导入什么类等。

debug 下， 看看到底走到哪一步 出错了，再结合这个错误仔细研究一下 应该会有答案的

The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
说明了jar包的版本有冲突

[bits_110]

没有这两个包
