I have included the struts-default.xml in init-param in web.xml as suggested by some posts.

Still it is not working!!

Am I missing anything?

web.xml is similar as below

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://java.sun.com/xml/ns/javaee"

   id="WebApp_ID" version="3.0">

      <filter-class>

   <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
   </filter-mapping>
</web-app>

struts.xml is similar as below

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
   "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
   "http://struts.apache.org/dtds/struts-2.0.dtd">

      </action>
   </package>
</struts>

Answer 1

1. Drop the FilterDispatcher that is deprecated, and set the new filter.
2. Correct your DTDs: in web.xml you are mixing 2.5 with 3.0. All 2.5 or all 3.0 (or all 2.4, according to your application server specs). In struts.xml, it should be 2.3 unless you are using a really old version (and you should not).
3. Make sure you have included all the required dependencies, each one only once, and all with the right versions.
