Question

I am creating a HelloWorld web/spring application from scratch. I have followed this tutorial in order to learn how to use the mvc pattern. So, after finished all steps and starts to run the application I received this error in console:

Grave: Context initialization failed
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 11 in XML document from ServletContext resource
[/WEB-INF/dispatcher-servlet.xml] is invalid; nested exception is
org.xml.sax.SAXParseException; lineNumber: 11; columnNumber: 100;
cvc-complex-type.2.4.c

Searching around SO question I found some threat like below but have not resolved my error.

• Cannot find the declaration of element 'beans' in internet offline mode
• Spring Security beginner's question. Build failed

So, I deduced that could be the dispatcher-servlet.xml at WEB-INF folder. This xml looks like:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:beans="http://www.springframework.org/schema/beans"
    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-3.1.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">


    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/jsp/</value>
        </property>

        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors">
            <list>
                <ref local="localeChangeInterceptor" />
            </list>
        </property>

        <property name="urlMap">
            <map>
                <entry key="/hello.html">
                    <ref bean="helloController" />
                </entry>
            </map>
        </property>

    </bean>

    <bean id="helloController" class="controllers.HelloController">
    </bean>

    <bean id="localeChangeInterceptor"
        class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">

        <property name="paramName" value="hl" />

    </bean>

    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
    </bean>

</beans>

Finally these are my included jars:

commons-logging-1.1.1.jar

org.springframework.aop-3.1.2.RELEASE.jar
org.springframework.asm-3.1.2.RELEASE.jar
org.springframework.aspects-3.1.2.RELEASE.jar

org.springframework.web.struts-3.1.2.RELEASE.jar

spring-webmvc-3.0.5.RELEASE.jar

Thanks in advance

EDIT 1:

After make the changes of @Biju Kunjummen, looks like now the problem is that there is a comflic in bean declaration:

Grave: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMapping' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Cannot resolve reference to bean 'helloController' while setting bean property 'urlMap' with key [TypedStringValue: value [/hello.html], target type [null]]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloController' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [controllers.HelloController]: Constructor threw exception; nested exception is java.lang.Error: Unresolved compilation problems: 
    The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files
    Implicit super constructor Object() is undefined for default constructor. Must define an explicit constructor
    String cannot be resolved to a type

I have checked the controller and looks fine into src/controllers dir:

package controllers;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloController implements Controller {

    public ModelAndView handleRequest(HttpServletRequest request,
              HttpServletResponse response) throws ServletException, IOException {

              String Mess = "Hello World!";

              ModelAndView modelAndView = new ModelAndView("hello");
              modelAndView.addObject("message", Mess);

              return modelAndView;
              }

}

Answer 1

You have the http://www.springframework.org/schema/mvc as the default, but your bean definitions belong to the http://www.springframework.org/schema/beans namespace, that should be the issue.

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:beans="http://www.springframework.org/schema/beans"
...">


<beans:bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix">
        <beans:value>/WEB-INF/jsp/</beans:value>
    </beans:property>

…..

Or make beans namespace the default this way:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans"
    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-3.1.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">


    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/jsp/</value>
        </property>

        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
