  • tomcat
  • 服务器
  • 百度
  • web
  • xml
  • java

    • 今天启动tomcat服务器就报出来以下异常，百度了一下，有人说是jdk版本和tomcat的版本不兼容，但我感觉不是，我将tomcat目录下的项目删除后就回复正常了，从抛出的异常来看是不是web.xml文档有问题

    java.lang.reflect.InvocationTargetException

    • systemId: jndi:/localhost/Web/WEB-INF/web.xml; lineNumber: 20; columnNumber: 21; Error at (20, 21) : The servlets named [Kenan] and [Kenan] are both mapped to the url-pattern [] which is not permitted

      一个提示很明显了，你有两个同名的servlet kenan，其中一个改名就对了
