Method Detail

authenticate

public void authenticate(String username,
                         String host,
                         String password)
                  throws IOException,
                         org.jivesoftware.smack.XMPPException

Builds and sends the auth stanza to the server. Note that this method of authentication is not recommended, since it is very inflexible. Use authenticate(String, String, CallbackHandler) whenever possible.

Overrides:

authenticate in class org.jivesoftware.smack.sasl.SASLMechanism

Parameters:

username - the username of the user being authenticated.

host - the hostname where the user account resides.

password - the password for this account.

Throws:

IOException - If a network error occurs while authenticating.

org.jivesoftware.smack.XMPPException - If a protocol error occurs or the user is not authenticated.

authenticate

public void authenticate(String username,
                         String host,
                         CallbackHandler cbh)
                  throws IOException,
                         org.jivesoftware.smack.XMPPException

Builds and sends the auth stanza to the server. The callback handler will handle any additional information, such as the authentication ID or realm, if it is needed.

Overrides:

authenticate in class org.jivesoftware.smack.sasl.SASLMechanism

Parameters:

username - the username of the user being authenticated.

host - the hostname where the user account resides.

cbh - the CallbackHandler to obtain user information.

Throws:

IOException - If a network error occurs while authenticating.

org.jivesoftware.smack.XMPPException - If a protocol error occurs or the user is not authenticated.

challengeReceived

public void challengeReceived(String challenge)
                       throws IOException

The server is challenging the SASL mechanism for the stanza he just sent. Send a response to the server's challenge.

Overrides:

challengeReceived in class org.jivesoftware.smack.sasl.SASLMechanism

Parameters:

challenge - a base64 encoded string representing the challenge.

Throws:

IOException - if an exception sending the response occurs.
