HTTP状态500 - 处理JSP页面时发生异常

时间：2015-12-12 18:49:10

标签： java spring jsp tomcat

我正在使用Eclipse和Tomcat Server 7开发一个带有String框架的Web应用程序。运行时我遇到同样的错误：

  

HTTP状态500 - 在第19行处理JSP页面/views/misc/index.jsp时发生异常

第19行是：<jsp:forward page="/welcome/index.do" />

有时它会在我不断刷新页面时起作用，但我不知道为什么。

杂项/ index.jsp的 

<%--
 * index.jsp

 --%>

<%@page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

<%@taglib prefix="jstl" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@taglib prefix="security" uri="http://www.springframework.org/security/tags"%>
<%@taglib prefix="display" uri="http://displaytag.sf.net"%>

<jsp:forward page="/welcome/index.do" />

这是欢迎视图的index.jsp页面

我认为问题出在jsp：forward。在该标记中使用index.jsp而不是index.do
