The matching wildcard is strict, but no declaration can be found for element 'context:component-scan' error in dispatcher servlet

Question

When I am trying to view the webpage on the browser I receive this error.

stacktrace :

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 10 in XML document from ServletContext resource [/WEB-INF/DefaultServlet-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 10; columnNumber: 71; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.

DefaultServlet-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:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

    <mvc:annotation-driven />
    <context:component-scan base-package="com.projectShaun.controller" />
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

Also I will include my applicationContext as it also have the same line of code in:

  </bean>

  <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" 
    p:sessionFactory-ref="sessionFactory">
  </bean>
</beans>

I also believe I have the correct dependency in my library and pom:

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>

Answer 1

According to this post " You have not specified the schema location of the context namespace, that is the reason for this specific error ".

However, it seems that you have it, so lets see what else can it be.

One option can be that you can specify the version of spring-beans because you are using 3.2 in your applicationContext , so might be beneficial to use the same one in DefaultServlet-servlet.xml .

Another thing which I feel worried is path http://www.springframework.org/schema/p , as I understand for this you don't need to specify the schemaLocation . It seems to be right, but I don't see that much of advantage here plus some of the XML namespaces are not used. So, I modified it and got this, try if it helps, hope it does.
