Using the JACC PolicyContext to Access the Current ServletRequest

You can access the current servlet request to gain access to request header information using the JACC PolicyContext API:

import javax.security.jacc.PolicyContext;
import javax.security.jacc.PolicyContextException;

   /** The JACC PolicyContext key for the current Subject */
   public static final String WEB_REQUEST_KEY = "javax.servlet.http.HttpServletRequest";


   HttpServletRequest request = (HttpServletRequest) PolicyContext.getContext(WEB_REQUEST_KEY);
