Method Detail

login
public abstract void login(Subject subject, CallbackHandler handler) throws LoginException
Log in to this provider.The provider relies on a
CallbackHandler
to obtain authentication information from the caller (a PIN, for example). If the caller passes anull
handler to this method, the provider uses the handler set in thesetCallbackHandler
method. If no handler was set in that method, the provider queries the auth.login.defaultCallbackHandler security property for the fully qualified class name of a default handler implementation. If the security property is not set, the provider is assumed to have alternative means for obtaining authentication information.- Parameters:
subject
- theSubject
which may contain principals/credentials used for authentication, or may be populated with additional principals/credentials after successful authentication has completed. This parameter may benull
.handler
- theCallbackHandler
used by this provider to obtain authentication information from the caller, which may benull
- Throws:
LoginException
- if the login operation failsSecurityException
- if the caller does not pass a security check forSecurityPermission("authProvider.name")
, where name is the value returned by this provider'sgetName
method
-
logout
public abstract void logout() throws LoginException
Log out from this provider.- Throws:
LoginException
- if the logout operation failsSecurityException
- if the caller does not pass a security check forSecurityPermission("authProvider.name")
, where name is the value returned by this provider'sgetName
method
-
setCallbackHandler
public abstract void setCallbackHandler(CallbackHandler handler)
Set aCallbackHandler
.The provider uses this handler if one is not passed to the
login
method. The provider also uses this handler if it invokeslogin
on behalf of callers. In either case if a handler is not set via this method, the provider queries the auth.login.defaultCallbackHandler security property for the fully qualified class name of a default handler implementation. If the security property is not set, the provider is assumed to have alternative means for obtaining authentication information.- Parameters:
handler
- aCallbackHandler
for obtaining authentication information, which may benull
- Throws:
SecurityException
- if the caller does not pass a security check forSecurityPermission("authProvider.name")
, where name is the value returned by this provider'sgetName
method
