MVC Crud Operations not working

Question

I'm performing emp CRUD operations with save and update operations using
Spring MVC, using SimpleUrlHandlerMapping. But when I run the project it is
throwing an error called /WEB-INF/MAC-servlet.xml not found. I created the above xml file in WEB-INF itself. Please solve this one. I added all Spring JARS along with MySQL connector. I'm using MySQL database to perform the operations.This is the following code of my project

empsave.jsp
_______________
<h1>Employee Save Form</h1>
<form action="./empsave.ds">
<pre>
Name:       <input type="text" name="name"/>
Email:      <input type="text" name="email"/>
Address:    <input rows="5" cols="15" name="address"/>
<input type="submit" value="save"/>
</pre>
</form>
