Subject: Joining a room and sending a message
Hi,
I am trying create a c# app using agsXMPP to be used in our nightly build process to broadcast messages to a particular room on our Jabber Wildfire server. So far I am able to login to our wildfire server using agsXMPP and send messages to users, but not to a room. I figured that I need to join a room first and then send a message but I can't seem to find any examples on how to do that with agsXMPP. Has anyone else tried to do this and is willing to share code?

Thanks

Hello,

the MiniClient examples supports groupchat. So take a look at it, all the code you need should be there.
Also take a look at the MucManager class. It's a wrapper for easier access to all groupchat related classes and functions.

Hi Alex,
Thank you for your prompt response. I think I have found the example you are referring to.
So I have the following code:

            ....
            jClient = new XmppClientConnection(); // Jabber Client Instance
            jClient.OnLogin += new ObjectHandler(jClient_OnLogin);
            jClient.OnError += new agsXMPP.ErrorHandler(jClient_OnError);
           
            jClient.Server = "*****";
            jClient.Username = "*****";
            jClient.Password = "*****";
            jClient.Port = 5222;
            jClient.Resource = "jabberin";
            jClient.Priority = 5;
            jClient.Status = "Online";
            jClient.Show = ShowType.NONE;
   
            try
            {
                jClient.Open();              
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            ......

private static void jClient_OnLogin(object sender)
        {
            jClient.SendMyPresence();

            MucManager mucManager = new MucManager(jClient);
            Jid Room = new Jid("room_name@eng-ops");
            mucManager.AcceptDefaultConfiguration(Room);
            mucManager.JoinRoom(Room, "room_name");
            jClient.Send(new Message(Room, "This is a test"));
            jClient.Close();
        }

For some reason the jClient_OnLogin function never gets called when I try to open the jClient connection. Am I not calling the jclient.open() properly?

Thanks

Hello,

you get the OnLogin event after successful authentication. If you don't get this event there must be an authentication problem.

Hi Alex,
So my athentication credentials work just fine, even in the miniclient example. I have the following code and can't figure out why I can authenticate:

using System;
using System.Collections.Generic;
using System.Text;
using agsXMPP;
using agsXMPP.protocol;
using agsXMPP.protocol.client;
using agsXMPP.protocol.x.muc;
using System.Threading;

namespace SendToJabber
{
    public class Program
    {
        private static XmppClientConnection jClient;

        public static void Main(string[] args)
        {
            jClient = new XmppClientConnection(); // Jabber Client Instance
            /**
             * Events for agsXMPP library
             * */
            jClient.OnLogin += new ObjectHandler(jClient_OnLogin);
            jClient.OnError += new ErrorHandler(jClient_OnError);
           
            jClient.Server = "eng-ops";
            jClient.Username = "*****";
            jClient.Password = "*****";
            jClient.Port = 5222;
            jClient.Resource = "jabberin";
            jClient.Priority = 10;
            jClient.UseSSL = false;
            jClient.SocketConnectionType = agsXMPP.net.SocketConnectionType.Direct;
            jClient.UseStartTLS = true;
            jClient.AutoResolveConnectServer = true;
            jClient.RegisterAccount = false;
   
            try
            {
                jClient.Open();              
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

        private static void jClient_OnLogin(object sender)
        {
            jClient.SendMyPresence();
            MucManager mucManager = new MucManager(jClient);
            Jid Room = new Jid("4xBuilds@eng-ops");
            mucManager.AcceptDefaultConfiguration(Room);
            mucManager.JoinRoom(Room, "4xBuilds");
            jClient.Send(new Message(Room, "This is a test"));
            jClient.Close();
        }

        private static void jClient_OnError(object sender, Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        private static void jClient_OnMessage(object sender, Message msg)
        {
            Console.WriteLine("Sending text: '" + msg.Body + "' to: " + sendTo);
        }
    }
}

None of the events seem be called and I get no exceptions.

Thanks

Looks like this is a console application. Your console application terminates after it leaves the Main function. The Open method is async and return immediately which terminates your program after the Open call. You have to prevent you code from terminating after opening the connection,

Hi Alex,
Great point. I have made the necessary changes and now the on_login event works correctly, and I am able to login to the server and send messages to users.
Thanks

Hi Alex,
One last question. For some reason I cannot joing the room by using mucmanager:
Here is the code that I am using:

            m_jClient.SendMyPresence();
            MucManager mucManager = new MucManager(m_jClient);
            Jid Room = new Jid("4xBuilds@conference.eng-ops");
            mucManager.AcceptDefaultConfiguration(Room);
            mucManager.JoinRoom(Room,"Builds");
            mucManager.LeaveRoom(Room, "Builds");
            m_jClient.Close();

Is the room format correct? I assume it should be room@conference.jabber_server, right?

Thanks

Hello,

if the room already exists then you only have to send your presence to the room which is done by the JoinRoom member of the MucManager.
If the room does not exists then you have to create it. Depending on your MUC component configuration the steps for creating a room can be different.

After you successful joined a room the muc server sends presence packets which are the presences from all occupants.
Can you post your debug xm?

This might sound dumb, but where do I capture the xm debug output?

Hi Alex,
Turns out that my code was correct. I had to rooms with the same name for some reason, and once I have deleted the duplicate, everything worked. Thanks for much for your help.
