Method Detail

authenticate

public void authenticate(java.lang.String username,
                         java.lang.String host,
                         javax.security.auth.callback.CallbackHandler cbh)
                  throws java.io.IOException,
                         XMPPException

Builds and sends the auth stanza to the server. This overrides from the abstract class because the initial token needed for GSSAPI is binary, and not safe to put in a string, thus getAuthenticationText() cannot be used.

Overrides:

authenticate in class SASLMechanism

Parameters:

username - the username of the user being authenticated.

host - the hostname where the user account resides.

cbh - the CallbackHandler (not used with GSSAPI)

Throws:

java.io.IOException - If a network error occures while authenticating.

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

                  throws java.io.IOException,
                         XMPPException

Builds and sends the auth stanza to the server. This overrides from the abstract class because the initial token needed for GSSAPI is binary, and not safe to put in a string, thus getAuthenticationText() cannot be used.
