Answer 1

Your configuration is flawed not to mention that it configures to much. For starters remove @EnableWebMvc from your LoginServlet as it isn't doing anything. It should be placed on a @Configuration based class and used in a Java Config based application you are using XML.

applicationContext.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"

       xsi:schemaLocation="
          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

         <context:component-scan base-package="com.webservlet">
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
         </context:component-scan>
</beans>

Should scan for everything but controllers (notice the exclude-filter ).

dispatcherServlet.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 http://www.springframework.org/schema/beans/spring-beans.xsd
          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
          http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

         <context:component-scan base-package="com.webservlet" use-default-filters="false">
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
         </context:component-scan>

          <mvc:annotation-driven />

          <mvc:view-controller path="/index.html" view-name="index" />
          <mvc:view-controller path="/home.html" view-name="home" />
          <mvc:view-controller path="/login.html" view-name="login />
          <mvc:view-controller path="/about_us.html" view-name="about_us" />
          <mvc:view-controller path="/contact_us.html" view-name="contact_us" />

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" />

</beans>

Scan only for controllers, notice the include-filter and use-default-filters="false" attribute. Enable @RequestMapping parsing with <mvc:annotation-driven /> and for those pesky view controllers use <mvc:view-controller /> .

For more information on the mvc namespace I suggest a read of this section of the reference guide.

Another tip use versionless xsd files instead of the versioned one, this will take care of using the latest version of the xsd available on the classpath.
