/**
 * Bookmarks is used for storing and retrieving URLS and Conference rooms.
 * Bookmark Storage (JEP-0048) defined a protocol for the storage of bookmarks to conference rooms and other entities
 * in a Jabber user's account.
 * See the following code sample for saving Bookmarks:
 * 
 * 
 * Connection con = new XMPPConnection("jabber.org");
 * con.login("john", "doe");
 * Bookmarks bookmarks = new Bookmarks();
 * 
 * // Bookmark a URL
 * BookmarkedURL url = new BookmarkedURL();
 * url.setName("Google");
 * url.setURL("http://www.jivesoftware.com");
 * bookmarks.addURL(url);
 * // Bookmark a Conference room.
 * BookmarkedConference conference = new BookmarkedConference();
 * conference.setName("My Favorite Room");
 * conference.setAutoJoin("true");
 * conference.setJID("[email protected]");
 * bookmarks.addConference(conference);
 * // Save Bookmarks using PrivateDataManager.
 * PrivateDataManager manager = new PrivateDataManager(con);
 * manager.setPrivateData(bookmarks);
 * 

 * 

 * LastActivity activity = LastActivity.getLastActivity(con, "[email protected]");
