XML : Tomcat 7 not reading web.xml

I've a S2 based web application. It's completely running on my local network. But while I deployed on cpanel its not running.

Problem: Tomcat 7 not reading web.xml file in cpanel.

if I invoke my url www.abc.com the index.jsp is displaying as home page. Actually I set home.jsp as home page to my application.

  <welcome-file-list>      <welcome-file>home.jsp</welcome-file>  </welcome-file-list>    

If I click on home link in index.jsp (contains menu) then it displays error as

  Not Found    The requested URL /index.action was not found on this server.    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.    

I didn't understand whats the problem here. Previously I've S1 based web application on the same domain www.abc.com. Its working fine. I didn't change any configurations just I deleted all the S1 related files and folders and deployed my new S2 based application. So in index.jsp file html based content is displaying.

If I print <%out.println("welcome");%> in index.jsp it prints welcome. So java working.

If I invoke like www.abc.com/wp-admin also I'm getting the above 404 error. Any suggestions please. If any extra information you need I will provide it.

struts.xml:

  <struts>  <constant name="struts.multipart.maxSize" value="30000000"/>  <package name="default" namespace="/" extends="struts-default">  <action name="index" class="com.myapp.ysrcptv.HomeAction">      <result>index.jsp</result>  </action>  ---------------
