Q:

Significance of the Servlet code

I am learning Servlets.
In web.xml of an application, I found the following Servlet code.
Can somebody please explain me the significance of the code
<servlet id="Servlet_1060120206078">
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param id="InitParam_1060120206077">
        <param-name>config</param-name>
        <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param id="InitParam_1060120206076">
        <param-name>debug</param-name>
        <param-value>2</param-value>
    </init-param>
    <init-param id="InitParam_1069371544495">
        <param-name>detail</param-name>
        <param-value>2</param-value>
    </init-param>
    <init-param id="InitParam_1069371544496">
        <param-name>validate</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
</servlet>

Thanks

A:

This is just defining a servlet (in this case a FrontController for Struts) that is used to handle requests. Later on in the file I'm sure you'll also find a servlet mapping that maps this servlet to http requests.
The <init-param> elements are key/value pairs that the servlet can read on startup. Struts uses these for configuration.
All the InitParam_XXX stuff is un-necessary, my guess is that it was machine generated by some editor.
