public class JAASCallbackHandler extends Object implements CallbackHandler
Implementation of the JAAS CallbackHandler
interface,
used to negotiate delivery of the username and credentials that were
specified to our constructor. No interaction with the user is required
(or possible).
This CallbackHandler
will pre-digest the supplied
password, if required by the <Realm>
element in
server.xml
.
At present, JAASCallbackHandler
knows how to handle callbacks of
type javax.security.auth.callback.NameCallback
and
javax.security.auth.callback.PasswordCallback
.

JAASRealm
instance.JAASRealm
instance specifies digested passwords,
the password
parameter will be pre-digested here.
Parameters: realm Our associated JAASRealm instance username Username to be authenticated with password Password to be authenticated with
Parameters: realm Our associated JAASRealm instance username Username to be authenticated with password Password to be authenticated with nonce Server generated nonce nc Nonce count cnonce Client generated nonce qop Quality of protection aplied to the message realmName Realm name md5a2 Second MD5 digest used to calculate the digest MD5(Method + ":" + uri) authMethod The authentication method in use
Callbacks
.
This implementation only recognizes NameCallback,
PasswordCallback and TextInputCallback.
TextInputCallback is ued to pass the various additional
parameters required for DIGEST authentication.
Parameters: callbacks The set of Callback
s to be processed
Throws: IOException if an input/output error occurs UnsupportedCallbackException if the login method requests an unsupported callback type
