Adding more functionality to Smack

Hi All,

   I'm using smack api to connect to openfire. I have added two more fields in package org.jivesoftware.xmpp.workgroup.Workgroup in fastpath plugin for openfire like this :-

     private String description = null;

    private Date creationDate;

    private Date modDate;

    private long offerTimeout = -1;

    private long requestTimeout = -1;

    private int maxChats;

    private int minChats;

// my addition is here

    private String email;

    private String timeZone;

. now I want to get these two properties using smack api but I don't know how and where this sholud happened in smack.

The workgroup in smack

org.jivesoftware.smackx.workgroup.user.Workgroup

only have the jid I need to get the other properties
