No mapping found for HTTP request with URI - Why erreur404

[fabian verbeek]

Hi,

I'm starting to learn spring and for this i tried the hello world.
Unfortunately i've an error404 when i attempt to load my hello.jsp

here is my pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com</groupId> <artifactId>tutoSpringMavenHibernate</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>tutoSpringMavenHibernate Maven Webapp</name> <url>http://maven.apache.org</url> <!-- Shared version number properties --> <properties> <org.springframework.version>3.0.5.RELEASE</org.springframework.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- Other dependencies --> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <scope>provided</scope> </dependency> <!-- Spring framework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework.version}</version> </dependency> </dependencies> <build> <finalName>tutoSpringMavenHibernate</finalName> </build> </project>

my spring-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:component-scan base-package="com.tutoSpringMavenHibernate.controller" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>

my controller:

package com.tutoSpringMavenHibernate.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
 
@Controller
public class HelloWorldController {
 
    @RequestMapping("/tutoSpringMavenHibernate/hello")
    public ModelAndView helloWorld() {
 
        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

here is my index.jsp thant can call hello.jsp

<html>
<head>
    <title>Spring 3.0 MVC Series: Index - ViralPatel.net</title>
</head>
<body>
    <a href="hello.html">Say Hello</a>
</body>
</html>

So when i click on the link i've an error404 and the console return this:
No mapping found for HTTP request with URI [/tutoSpringMavenHibernate/hello.html] in DispatcherServlet with name 'spring'

thanks for your help

[Kr. Pallav]

Change

  @RequestMapping("/tutoSpringMavenHibernate/hello")  

to

  @RequestMapping("/hello")  

[fabian verbeek]

I've already tested this but still the same error

[Kr. Pallav]

Add <context:annotation-config />
to xml and check if your jsp hello.jsp is inside WEB-INF/jsp folder

[fabian verbeek]

hi,

i added the line : <context:annotation-config />
before the line: <context:component-scan base-package="com.tutoSpringMavenHibernate.controller" /> in my spring-servlet.xml

My page hello.jsp is well under WEB-INF/jsp
If i try to load it with welcome-file in web.xml it works

Somebody has an other idea :-s

thanks for your help

[Kr. Pallav]

In web.xml
<servlet> <servlet-name>spring</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping>

Change is
<url-pattern>*.html</url-pattern>

[fabian verbeek]

unfortunately it doesn't work again :-(

Does it come from my dependencies in my pom?
still again the error404

thanks and hope makes it work

[fabian verbeek]

i'm really disapointed with this error :-s

Nobody has a solution to make it works or a tutorial

thanks

You have a couple problems. You are creating the context twice once for the webcontext (defaults to servletName-servlet.xml if you don't have it defined) and you are defining a root context using the same configuration.

Take a look at this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

	<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring/root-context.xml</param-value>
	</context-param>
	
	<!-- Creates the Spring Container shared by all Servlets and Filters -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- Processes application requests -->
	<servlet>
		<servlet-name>appServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
		
	<servlet-mapping>
		<servlet-name>appServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

In the example I have explicitly defined the name of the dispatcher servlet context. If I don't do that it will look using the convention I explained above. In your case you are using the exact same configuration for creating 2 contexts. Either use 2 separate ones and leave your root-context empty for now or you can opt out of having to have a separate servlet context by leaving the tag empty like this

<servlet>
		<servlet-name>appServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value></param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
</servlet>

Also add this to your spring.xml config file (including the mvc namespace at the top)

<mvc:annotation-driven />

finally make sure you are accessing it using the correct context root. (don't include the context root as part of your mapping in your controller handler as someone else already mentioned)

[Bill Gorder]

Also you can remove

    <context:annotation-config />  

it is unnecessary if you are using component scan.

thanks a lot for your explanation.


i tested but i've always the same error404 :-s

here is my new web.xml:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Archetype Created Web Application</display-name> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> <welcome-file>/WEB-INF/jsp/hello.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/root-context.xml</param-value> </context-param> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> </web-app>

my spring-servlet.xml under WEB-INF/spring/appServlet
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!--<context:annotation-config /> what about this tag? <resources mapping="/resources/**" location="/resources/" />--> <mvc:annotation-driven /> <context:component-scan base-package="com.tutoSpringMavenHibernate.controller" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <!-- Root Context: defines shared resources visible to all other web components --> </beans>

my index.jsp under the root path and my hello.sp under WEB-INF/jsp
I call it from index.jsp on calling it with: <a href="hello.html">Say Hello</a>

finally here is my controller:

package com.tutoSpringMavenHibernate.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
 
@Controller
public class HelloWorldController {
 
    /*public String home() {
        System.out.println("HomeController: Passing through...");
        return "WEB-INF/jsp/hello.jsp";
    }*/
    @RequestMapping("/hello")
    public ModelAndView helloWorld() {
 
        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

What is my mistake? i'm a php developer and it's really difficult to me to understand.

thans for your helps

[fabian verbeek]

it should come an issue with maven or eclipse because i tried without maven and in including the necessary jar in lib folder of tomcat it works.

Here is the lib i used:
commons-logging.jar
org.springframework.asm-3.1.2.RELEASE.jar
org.springframework.beans-3.1.2.RELEASE.jar
org.springframework.context-3.1.2.RELEASE.jar
org.springframework.core-3.1.2.RELEASE.jar
org.springframework.expression-3.1.2.RELEASE.jar
org.springframework.web.servlet-3.1.2.RELEASE.jar
org.springframework.web-3.1.2.RELEASE.jar
javax.servlet.jsp.jstl-1.2.1.jar

thanks for your helps
