Struts.xml is inside the Web-INF folder. web.xml and Struts.xml are in the same folder. — Kandasamy Karuppiah, Mar 20 '16 at 13:05
It should be on classpath or otherwise you should change init parameter. — Roman C, Mar 20 '16 at 13:29

The class path of the action you mentioned in struts.xml actions.HomeScreen is not same as your class package com.cmdb.actions These must be the same.

The struts.xml file must be under the ../WEB-INF/classes folder, which you have to create manually and move your struts.xml file to it.

Your /WEB-INF folder tree should look something like the following:

../WEB-INF
../WEB-INF/classes
../WEB-INF/classes/struts.xml
../WEB-INF/web.xml

Also, as @Alireza mentionned, you should set your class attribute in struts.xml as following class="com.cmdb.actions.HomeScreen"

This will get you up and running.
