Java – Spring Security login returns 404

I am currently working on my blog in Spring framework. I am implementing the Spring Security for login purpose. Everything works as expected until I submit the login credentials which is always returning 404 code.

Here is my web.xml code

<?xml version="1.0" encoding="UTF-8"?>

Here is my spring security code:

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/avispring"/>
    <property name="username" value="root"/>
    <property name="password" value=""/>
</bean>
<security:debug/>
<security:http auto-config="true">
    <security:intercept-url pattern="/admin/**" access="hasRole('ROLE_ADMIN')"/>
    <security:intercept-url pattern="/j_spring_security_check" access="permitAll"/>
    <security:form-login        
    login-page="/login.html"
    authentication-failure-url="/login?login_error=1"
    default-target-url="/admin/home.html"/>     
</security:http>

<security:authentication-manager>
    <security:authentication-provider>
        <security:jdbc-user-service 
            data-source-ref="dataSource"
            users-by-username-query="select USERNAME,PASSWORD,ENABLED from USER_AUTHENTICATION where USERNAME=?"
            authorities-by-username-query="select u1.USERNAME,u2.ROLE from USER_AUTHENTICATION u1,USER_AUTHORIZATION u2 where u1.USER_ID=u2.USER_ID and u1.USERNAME=?"/>
    </security:authentication-provider>
</security:authentication-manager>

part of my login.jsp code is

<form action="<c:url value="/login"/>" method="post">
      <div class="form-group has-feedback">
        <input type="email" class="form-control" placeholder="Email" name="username">
        <span class="glyphicon glyphicon-envelope form-control-feedback"></span>
      </div>
      <div class="form-group has-feedback">
        <input type="password" class="form-control" placeholder="Password" name="password">
        <span class="glyphicon glyphicon-lock form-control-feedback"></span>
      </div>
      <div class="row">
        <div class="col-xs-8">
          <div class="checkbox icheck">
            <label>
              <input type="checkbox"> Remember Me
            </label>
          </div>
        </div><!-- /.col -->
        <div class="col-xs-4">
          <button type="submit" class="btn btn-primary btn-block btn-flat"     name="submit">Sign In</button>
        </div><!-- /.col -->
      </div>
    </form>

and the console output is

Oct 16, 2015 1:06:03 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/avispring/login] in DispatcherServlet with name 'spring'

Note:

1. I am using spring 4.2.1 and spring security 4.0.2
2. Most of the forums are pointing to the context path i.e [appname/login] or [appname/j_spring_security_check] and I think mine is ok regarding it

Please help…

UPDATE:

when I used log4j, the debug output at the time of form submission is as follows:
