SASL authentication error while integrating facebook chat using smack

Question

I am trying to integrate facebook chat using smack API. But I get an error message with an error using digest md5 ...

Here is the authentication code:

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); 

The following is the error with which 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 I have no success vit fb ... can sumone contact me with a problem

Answer 1

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

eg.

 connection.login(" [e-mail] ", "password", "resource"); 

becomes

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

Answer 2

There is a huge stream in Ignite that deals with this issue. You can take a look at it, as there are several Java and Android solutions that seem to work.

Answer 3

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

I used the class presented here with success

You should also note that in the DIGEST-MD5 engine, you need to log in with your facebook username and not your email address. By default, facebook accounts do not have a username, you need to create a single file, you can check it here:

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