HTTP - 500 org.springframework.web.util.NestedServletException: Handler processing failed;_问答_开发者

I'm using :

Apache Tomcat 6.0.20
Spring 3.x

I want to create simple "Hello World !!!" on my index page. Unfortunately, I get the following error:

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config
    org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:820)
    org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716)
    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)
    org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:549)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

this is my controller called IndexController.java

package com.dprima.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {
    @RequestMapping("/index")
    public ModelAndView index(){
        String message = "Hello World !!!";
        return new ModelAndView("index","hello",message);
    }
}

my web.xml

        <welcome-file>redirect.jsp</welcome-file>
      </welcome-file-list>
</web-app>

my dispatcher-servlet.xml

 ...
        <context:component-scan base-package="com.dprima.controller" />

        <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.Jst开发者_运维百科lView" />
            <property name="prefix" value="/WEB-INF/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean> 
    ...

my redirect.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("index.php"); %>

my index.jsp

<html>
<head>
    <title>Spring 3</title>
</head>
<body>
    ${hello}
</body>
</html>

I have added all JARs including jstl.jar & standard.jar because I assume this will required for the java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config error. However, it still displays HTTP 500 for the http://localhost:8080/passion/index.php and HTTP 404 for http://localhost:8080/passion/.

JARs should be in WEB-INF/lib, not subdirectories.

If you're deploying on Tomcat, you might try putting those JSTL JARs in the Tomcat /lib so the server class loader can find them.

I think that you must be use tomcat and your pom.xml is like:

<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>jstl-api</artifactId>
    <version>1.2</version>
    <scope>provided</scope>
</dependency>

delete the scope node, or change "provided" to "compile" then maven copy jstl-api-1.2.jar to the WEB-INF/lib.

then OK.

, Why do you redirect this page using?

<% response.sendRedirect("index.php"); %>

you can map index php as a welcome file. I did it the following way:

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/index.php</url-pattern>
  </servlet-mapping>

and then:

 <welcome-file-list>
        <welcome-file>index.php</welcome-file>
      </welcome-file-list>

it will show your index.dlp as index file. Danny.
