Issue with name appServlet-servlet.xml - spring

Question

Hi guys I'm working with Spring 3.2.3, hibernate 4.2.2 and org.springframework.security 3.0.5. Before I start working with security in spring, my context file was called servlet-context.xml and everything worked fine. Since I start using org.springframework.security 3.0.5 when I try to run my application I get the error:
java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/appServlet-servlet.xml]
My web.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<!-- Spring MVC -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/servlet-context.xml,
/WEB-INF/spring-security.xml
</param-value>
</context-param>
<!-- Spring Security -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>
org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Notice that I'm specifying my servlet-context.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/servlet-context.xml,
/WEB-INF/spring-security.xml
</param-value>
</context-param>
If I leave my web.xml just like this and copy/paste my servlet-context.xml content in a new file called appServlet-servlet.xml, everything works fine. This is confusing for me since I told web.xml that my context file name was servlet-context.xml. Am I forced to call my context file as appServlet-servlet.xml??. Of course, if I delete servlet-context.xml and leave appServlet-servlet.xml making the specficiation in web.xml, works fine.
I just wanna know if is obligatory to call my context file as appServlet-servlet.xml if I want to use spring security in my app.

This is not strange. Spring works this way. Since your DispatchServlet name is appServlet, Spring automatically tries to find the servlet context that has the same name, here "appServlet-servlet.xml".
