Is it possible to run spring-orm program using dispatcher-servlet.xml only. Without using ContextLoaderListener and applicationcontext.xml? If yes then how?

Secondly why is it necessary to register dispatcher-servlet.xml or applicationcontext.xml in web.xml? Because when these files are not registered in web.xml all the setter injections(specified in dispatcher-servlet.xml or applicationcontext.xml) take place on server start-up that means these xml files are loading without registering in web.xml.

    Is it possible to run spring-orm program using dispatcher-servlet.xml only. Without using ContextLoaderListener and applicationcontext.xml?

    Yes, that’s fine.

    If yes then how?

    You just do it. Put everything you need into dispatcher-servlet.xml, it’ll operate on its own. While it’s common practice to put DAO-related stuff in applicationContext.xml and MVC stuff in dispatcher-servlet.xml, it’s by no means a requirement. It can all sit in one file if you choose.

    Secondly why is it necessary to register dispatcher-servlet.xml or applicationcontext.xml in web.xml? Because when these files are not registered in web.xml all the setter injections(specified in dispatcher-servlet.xml or applicationcontext.xml) take place on server start-up that means these xml files are loading without registering in web.xml.

    Because if you don’t specify them in web.xml, Spring will use its defaults and look for them anyway. DispatcherServlet will look for <servlet-name>-servlet.xml, and ContextLoaderListener will look for /WEB-INF/applicationContext.xml by default. You can override this in web.xml if you choose.
