问题是这样的，最近部署一个项目，发现每次访问首页的时候老是报如下的错误:

按照报错信息，问题应该是出在jstl上面，要么是没有导入jstl的jar包，要么是没有引入jstl标签，我检查了项目发现这些都没有问题，按照网上的很多做法，依然没有解决我的问题，这个问题大概折腾了我大概一周左右，依然没法解决，最后非常沮丧，可是沮丧归沮丧，问题总归是要处理的，而我又坚信没有解决不了的问题。于是我想到了我之前部署的该项目有个版本是没有问题，现在也已经在线上运行良好，所以我就想到了对比两个项目的jar包，我以为是这个版本新加的某些jar包有问题，所以一个一个的对jar包，把出问题的这个版本多余的jar包全部删除了，保持和之前没有问题的那个版本的jar包一模一样，可是问题还没有解决，最后我把之前没有问题的版本的jar全部拷贝过来全部替换掉现在的jar包，问题于是很奇怪的解决了，我很纳闷，于是一个个的找问题，最后发现问题出现的jstl上面，都是jstl1.2版本的，居然一个有问题，最后我把本地maven仓库的jstl删除了，重新下载这个版本的jstl，也没有问题了。最后我觉得问题可能是，我刚好下载到了有问题的jstl，估计jstl的开发人员当时刚好提交了有问题的jstl，可刚好被我下载到了，虽然最后又进行了修复，可是我的仓库里面已经是有问题的jstl了。

解压有问题的jstl的jar包，报如下错误：
