Hello all,

I have created a roster plugin that will return a users roster in xml format.

I make a call to the servlet passing a jid and the servlet makes a call to the Roster_Plugin that will return a XML String.

I have the plugin itself, a servlet and a class file.

If I restart Openfire, my plugin breaks and will return the openfire login page.

I cannot get my plugin to run again unless I uninstall and reinstall plugin.

Here is the code of my Plugin:

 
//imports removed for brevity
 
/**
 * Roster plugin for Openfire.
 */
public class Roster_Plugin implements Plugin
{
 
    private static String AVAILABLE = "icon-im_available";
    private static String OFFLINE   = "icon-im_unavailable";
    private static String AWAY      = "icon-im_away";
    private static String DND       = "icon-im_dnd";
    private static String XA        = "icon-im_xa";
   
    XMPPServer server;
    UserManager userManager;
    PresenceManager presenceManager;
   
    public void initializePlugin(PluginManager manager, File pluginDirectory)
    {
        server          = XMPPServer.getInstance();
        userManager     = server.getUserManager();
        presenceManager = server.getPresenceManager();
        Log.info("Creating RosterPlugin");
    }
 
    public void destroyPlugin()
    {
        server          = null;
        userManager     = null;
        presenceManager = null;
        Log.info("Destroying Rosterplugin");
    }
 
 
    //Returns an XML string of a users roster called from servlet.
    public String getRoster(String _userName) {
        Roster roster = null;
        HashMap<String, ArrayList> hashMap = new HashMap<String, ArrayList>();
        ArrayList<User> arrayList = new ArrayList<User>();
        String userName = _userName;//We want this persons roster
        StringBuffer rosterBuffer = new StringBuffer();//StringBuffer to hold the roster string.
        try {
            User u            = userManager.getUser(userName);
            roster            = u.getRoster();
            User user         = null;//User object needed to attain Presence.
            List<RosterItem> rosterItems = new ArrayList<RosterItem>(roster.getRosterItems());
            Collections.sort(rosterItems, new RosterItemComparator());
            for (RosterItem rosterItem : rosterItems) {
                List<String> group = rosterItem.getGroups();
                user = userManager.getUser(rosterItem.getJid().toString());
                for(String groupString : group) {
                   if(groupString != null) {
                        if(!hashMap.containsKey(groupString)) {
                            arrayList = new ArrayList<User>();
                            arrayList.add(user);
                            hashMap.put(groupString, arrayList);
                        }
                        else if(hashMap.containsKey(groupString)) {
                            arrayList = hashMap.get(groupString);
                            arrayList.add(user);
                            hashMap.put(groupString, arrayList);
                        }
                        else {
                        }
                   }
                   else {//TODO;                      
                   }
                }
            }
            rosterBuffer.append(this.parseHashList(hashMap, user).toString());
        }
        catch(UserNotFoundException unfe){Log.error("USER NOT FOUND:" + unfe.getMessage());}
        return rosterBuffer.toString();
    }
   
 

Here is my servlet code:

public class RosterServlet extends HttpServlet {
    
    private Roster_Plugin plugin;
    
    /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        
        plugin = (Roster_Plugin) XMPPServer.getInstance().getPluginManager().getPlugin("rosterplugin");
        AuthCheckFilter.addExclude("rosterplugin");
        String userName = request.getParameter("username");
        String roster   = plugin.getRoster(userName.trim());
        response.setContentType("text/xml;charset=UTF-8");
        PrintWriter out = response.getWriter();
        out.println(roster);
        out.close();
    }
}
 

It seems like the plugin loses the AuthCheckFilter on restart and never gets it back.

I get no error messages in admin log and I have it on debug.

Any Ideas?

My jar file directory structure is as follows:

classes --> com --> myorg --> Roster_Plugin.class and RosterServlet.class

META-INF --> Manifest.mf

web> WEB-INF> web-custom.xml

plugin.xml

OK,

I dont need to redeploy the plugin on restart.

If I access my servlet using http://localhost:9090/plugins/rosterplugin/roster?username=gforty

I get prompted to login to the admin console.

If I login, I get the expected roster XML string for username gforty.

Now if I access the servlet again with a different username, I also get the expected roster XML string.

Now if I go to a different machine or browser and access the servlet, I am once again prompted to login if I just restarted Openfire.

It is almost like the AuthCheckFilter is not initialized until I access the servlet 1 time through the login page.
