I have decided to use the smack API along with openfire.. But I need little guidance as to how to use it with openfire server..

What about Smack API Getting Started?

And does the openfire provide a basic UI like log in box chat window etc...

OpenFire is just the Server. To actually chat, you'll need some Jabber/XMPP Client. You could use Spark for tests.

Configure openfire then refer to documentation provided by Smack. It has easy to understand examples. FYI openfire works fine with gtalk but with facebook it is very slow.

---

Sample code:-

ConnectionConfiguration config = new ConnectionConfiguration(host, 5222);
XMPPConnection connection = new XMPPConnection(config);
connection.connect();
connection.login(user_name, password);

Here host is the ip/domain name where openfire is configured.

This is a sample, which will help set the status message on gtalk.

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.packet.Presence;

public class SmackToGtalk {
public static void main(String[] args) 
{
    ConnectionConfiguration config = new ConnectionConfiguration(
            "talk.google.com", 5222, "google.com");
    XMPPConnection connection = new XMPPConnection(config);
    Presence presence;
    String status;

    try {
        connection.connect();
        connection.login("[email protected]", "password");
        status = "DND";

        presence = new Presence(Presence.Type.available, status, 24,
                Presence.Mode.available);
        while (true) {
            status = set(status);
            presence.setStatus(status);
            connection.sendPacket(presence);
            Thread.sleep(1000);
        }

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        connection.disconnect();
    }
}

private static String set(String input) {
    return input.substring(1) + input.charAt(0);
}
}

In JSP / Java, import the smack.jar

<%@ page import="org.jivesoftware.smack.*;" %>

Place smack.jar in

tomcat/lib 

or yourwebapp/WEB-INF/lib

@Tim-It does not tell how I am supposed t it with openfire...Like should I plug in the smack or is there a different step

[newbie]

@Harry-I have gone through the documentation but I dint see anywhere as to how to use smack with openfire...I have the openfire configured...

[Tim Büthe]

Sure, you set up the server like described here: igniterealtime.org/builds/openfire/docs/latest/documentation‌​/…. Thereafter you can connect with some client or the smack API.

[newbie]

@Tim I have set up the openfire...I am askin how do I connect it with the smack API??

[Tim Büthe]

Do you have started? Post some source code along with the Exception you're getting...

[newbie]

@Tim...No what I meant was should I upload the jar files under plugins in openfire???

[Harry Joy]

@Kuber: to just simply use opefire with smack. No extra jar file is needed. But to work with gtalk/facebook you will requires plugins in openfire.

[newbie]

So where so I code for it??In eclipse..should I configure openfire in eclipse??

[Harry Joy]

@Kuber: no need to configure openfire in eclipse. Download SMACK jars. Then just create a java file copy/paste above code. replace username/host/password. Run the file.

[newbie]

So how does the openfire understand ??I mean I don see any set up or configuration..So how does the openfire know??

[Harry Joy]

@kuber: We are providing ip and port on which openfire is running.

[Tim Büthe]

I think you haven't understood the whole thing. You need some server that understand the XMPP-Protocol. In youe case that is OpenFire, GTalk or something else. When a client connects, it sends XMPP messages as described in the protocol, see Wikipedia: en.wikipedia.org/wiki/…. So far so good, to implement a client, you could use the smack API. With this API you use Java to construct and send the XMPP messages mentioned above. So in a nutshell: The Smack API is no OpenFire Plugin and not needed on the server. You just use it to build a client.

hi any tell me wat is the host here

[Harry Joy]

@Kannappan: host is the ip or domain name of the machine where openfire is running.
