    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/nl/javaee/web-app_3_0.xsd"
    version="3.0" >  
  <display-name>portal</display-name>  
  <welcome-file-list>
  	<welcome-file>index.html</welcome-file>
  	<welcome-file>index.htm</welcome-file>
  	<welcome-file>index.jsp</welcome-file>
  	<welcome-file>default.html</welcome-file>
  	<welcome-file>default.htm</welcome-file>
  	<welcome-file>default.jsp</welcome-file>
