Tomcat 7 not reading web.xml

Hi, I've a struts 2 based web application, this application is running in my local system and later I deployed in cpanel. The problem is Tomcat is not reading web.xml file and java is working in my domain I checked with some out.println("welcome"); statement. It prints welcome message. Previously I've struts 1 based application in the same domain and its running perfectly. But my struts 2 based application is not running. In web.xml file, I configured home.jsp as welcome page. But server is taking index.jsp as welcome page by default. so its clear tomcat is not reading web.xml file. Key points: java is working. struts 1 based application is running. But struts 2 based application is not running. For more
