[Opensource] Updated: Added transaction token support for controllers

[Raul DAVIDOVICH]

Hi all,

      I reworked a bit the transaction token support.. I wasn't very happy
by modifying the PersistentSession interface, so instead of that, I added a
getHttpServletRequest() method in ControllerRequest who simplifies things a
bit..

here are the code snippets, the .class files and the .java sources


Controller.java

...

/**
     * Generate a new transaction token, to be used for enforcing a single
     * request for a particular transaction.
     *
     * @param request The request we are processing
     */
     protected String generateToken(ControllerRequest request) {
        return (super.generateToken(request.getHttpServletRequest()));
    }



     /**
     * Return <code>true</code> if there is a transaction token stored in
     * the user's current session, and the value submitted as a request
     * parameter with this action matches it.  Returns <code>false</code>
     * under any of the following circumstances:
     * <ul>
     * <li>No session associated with this request</li>
     * <li>No transaction token saved in the session</li>
     * <li>No transaction token included as a request parameter</li>
     * <li>The included transaction token value does not match the
     *     transaction token in the user's session</li>
     * </ul>
     *
     * @param request The servlet request we are processing
     */
    protected boolean isTokenValid(ControllerRequest request) {
        return(super.isTokenValid(request.getHttpServletRequest()));
    }


    /**
     * Reset the saved transaction token in the user's session.  This
     * indicates that transactional token checking will not be needed
     * on the next request that is submitted.
     *
     * @param request The servlet request we are processing
     */
    protected void resetToken(ControllerRequest request) {
      super.resetToken(request.getHttpServletRequest());
    }


    protected void saveToken(ControllerRequest request) {
      super.saveToken(request.getHttpServletRequest());
    }

...


ControllerRequest.java

...
import javax.servlet.http.HttpServletRequest;
...

/**
     * Returns the HttpServletRequest
     *
     * @return javax.servlet.http.HttpServletRequest
     */
    public HttpServletRequest getHttpServletRequest() {
      if (mySession != null)
         return mySession.getRequest();
      else
       return null;
    }
...
