Implement Security in Web.xml

Use Case:3 We would like to exclude a set of web resources from any access. This can arise when a certain portion of the web application needs to undergo some form of maintenance or is not applicable for a particular physical deployment of a generic web application. We will achieve this with authorization constraints that specify no roles.

<security-constraint>
   <display-name>excluded</display-name>
   <web-resource-collection>
      <web-resource-name>No Access</web-resource-name>
      <url-pattern>/excluded/*</url-pattern>
      <url-pattern>/restricted/employee/excluded/*</url-pattern>
      <url-pattern>/restricted/partners/excluded/*</url-pattern>
   </web-resource-collection>
   <web-resource-collection>
      <web-resource-name>No Access</web-resource-name>
      <url-pattern>/restricted/*</url-pattern>
      <http-method>DELETE</http-method>
      <http-method>PUT</http-method>
      <http-method>HEAD</http-method>
      <http-method>OPTIONS</http-method>
