SASL Authentication failed while integrating facebook chat using Smack

I am trying to integrate facebook chat using smack API.But i get an error telling authentication failed using digest md5...

Here s the code for authentication:

 SASLAuthentication.registerSASLMechanism("DIGEST-MD5", SASLDigestMD5Mechanism.class);
  SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);

    ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
    connection = new XMPPConnection(config);
    config.setSASLAuthenticationEnabled(true);
    connection.connect();
    connection.login(userName, password);

below is the error i get wen i run it:

Exception in thread "main" SASL authentication failed using mechanism DIGEST-MD5: 
    at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:325)
    at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395)
    at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:349)
    at JabberSmackAPIFacebook.login(JabberSmackAPIFacebook.java:31)
    at JabberSmackAPIFacebook.main(JabberSmackAPIFacebook.java:77)

I can successfully connect to gtalk but am having no success vit fb... can sumone tel me wat s the problem

For me the solution was to not include the host part in the username when calling login() without DNS SRV and not agains the Google Talk services. This is also described in the ignite forums.

E.g.

connection.login("user@jabber.org", "password", "resource");

becomes

connection.login("user", "password", "resource");

There is a huge thread at Ignite that deals with this issue. You may want to take a look at it as there are several solutions for Java and Android given that seem to work.

I have succesfully connected using DIGEST-MD5 to facebook, the code you have posted looks good. But still we need to check the contents of your SASLDigestMD5Mechanism class

I have used the class provided in here with success

http://community.igniterealtime.org/message/200878#200878

Also you have to notice that in the DIGEST-MD5 mechanism you have to login with your facebook username and not with the email address. By default the facebook accounts don't have a username, you have to create one fisrt, you can check that in here:

http://www.facebook.com/username/
