我错了getting:-

  1. org.apache.catalina.core.ApplicationDispatcher invoke
  2. SEVERE: Servlet.service() for servlet [jsp] threw exception
  3. java.lang.ClassNotFoundException: javax.el.ELResolver

我刚接触过SpringWebMVC和hibernate，我试图用jstl核心标记显示从数据库中获取的记录，但是我遇到了这个错误，我尝试手动添加外部jar，尝试添加jar作为依赖项，我重新安装了tomcat并尝试了不同的版本，我基本上在stackoverflow上尝试了与此问题相关的所有解决方案，我尝试了stackoverflow和其他网站上提到的大约20个解决方案，但都不起作用，请帮助我解决问题。我是在严重的最后期限，我一直试图解决，因为过去几天，但我不能。
我试过的tomcat版本：8.5、9.0.34、9.0.44

非常感谢您的帮助，请帮我解决。我使用的是jdk1.8.0，仅供参考，我的tomcat主目录中有以下jar:el-api.jar、jasper.jar、jasper-el.jar、jsp-api.jar、jaspic-api.jar、servlet-api.jar。
