Dispatcher servlet not found. mvn install fails with file not found

Question

I have simple spring project using spring mvc. I have changed the dispatcher servlet name but mvn install fails with error.

Error stack trace : IOException parsing XML document from ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/dispatcher-servlet.xml]

1)web.xml

Not sure what I am missing here.

File structure in my code base

Your dispatcher servlet name should be unique. You likely told your compiler/Intepreter somewhere in your code(haven't seen it here) to look for dispatcher-servlet.xml at /WEB-INF/. But seems you named your dispatcher with mvc-dispatcher-servlet.xml. The java.io.FileNotFoundException exception might be as a result. Two things: Either you go to where you had dispatcher-servlet.xml and replace it with mvc-dispatcher-servlet.xml or you do the following:

Replace your dispatcher servlet name:

mvc-dispatcher-servlet

with

dispatcher-servlet

everywhere.

Add .xml extension to dispatcher-servlet where need be.

For instance, in your web.xml, you can do the following changes:

...

<!-- Loads Spring Security config file -->
<context-param>
    <param-name>contextConfigLocation</param-name>
     <param-value>        
        /WEB-INF/spring-security.xml,
        /WEB-INF/data-source-cfg.xml,
        /WEB-INF/dispatcher-servlet.xml <!--changed here -->
    </param-value>

</context-param>


<!-- Spring MVC -->
<servlet>
    <servlet-name>dispatcher</servlet-name> <!--changed here -->
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name> <!--changed here -->
    <url-pattern>/</url-pattern>
</servlet-mapping>

...

Note. I commented lines I made change on.
