I am using Spring MVC, Spring security and deploying in Apache Tomcat 1.7x. I notice that Web Application context is getting loaded twice. Please let me know what is wrong with my configuration.
I have referred below posts but could not identify the difference
Why Spring Context is loaded twice?,
Spring MVC web app: application context starts twice
INFO ContextLoader:273 - Root WebApplicationContext: initialization
started
Below is my web.xml

There are more than way to do this. The way that will work depends how servlet-context.xml are.
First, you can just remove <beans:import resource="servlet-context.xml" /> from your spring-security.xml.
Other way is remove this:
<!-- 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/appServlet/spring-security.xml</param-value>
</context-param>
And this:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
And include an import to spring-security.xml in servlet-context.xml.
A good practice is separate your configuration in multiple application contexts, import all in an applicationContext.xml and have a specific application context for the servlet context, something like this:
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.package" />
<import resource="applicationContext-security.xml"/>
<import resource="applicationContext-data.xml"/>
</beans>
applicationContext-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"

p:prefix="/WEB-INF/views/" p:suffix=".jsp" />
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver" p:order="3" p:defaultErrorView="error" />

And in your web.xml:
<!-- spring servlet -->

This happens with every web application with Spring Security, that I write, even if I just follow the instructions in tutorial.
I can not understand what is wrong. If you need anything else please let me know.
I need to add Spring Security with customized login page and connection to database to my Spring MVC project. I am receiving following error message, based on answers of other questions, I tried to change the code, for example I changed my Spring Security Schema version to 4.0 but the code returns following error:
Changed schema to 4.0
http://www.springframework.org/schema/security/spring-security-4.0.xsd
Error
Cannot initialize context because there is already a root application context
present - check whether you have multiple ContextLoader* definitions in your
web.xml!

I think you need have only one xml configuration file (my-servlet.xml as your servlet name is "my" so filename must be "my-servlet.xml") in web-xml and then refer others in that file. Refer to xmls below.

In my-servlet.xml file you can use import to compose your other XML configurations.
<beans>
<bean id="bean1" class="..."/>
<bean id="bean2" class="..."/>
<import resource="security-db.xml"/>
<import resource="foo-db.xml"/>
