There are a few issues with your setup.

First , the dispatcher servlet will automatically load the web application context - as defined by dispatcher-servlet.xml . You do not need to specify this in the contextConfigLocation for the ContextLoaderListener .

Since it doesn't look as though you have a root application context (which would normally be loaded by the ContextLoaderListener ), then you can remove the following from your web.xml :

 <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener
     </listener-class>
 </listener>

and

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>

Second , your dispatcher servlet is mapped to *.do but your controller and form action are both omitting the .do . Change your form and controller mapping to LoginAuth.do

Third , you should add <mvc:annotation-driven/> to your dispatcher-servlet.xml which activates the @RequestMapping annotations and tells Spring to register a bunch of other fairly useful beans behind the scenes.

For this, the mvc namespace should be added to the top of your dispatcher-servlet.xml :

xmlns:mvc="http://www.springframework.org/schema/mvc"

with a schema location of:

http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

Give that a try and see how you get on.
