Method Detail

initialize

public void initialize(Subject subj,
                       CallbackHandler handler,
                       Map<String,?> state,
                       Map<String,?> options)

Specified by:

initialize in interface LoginModule

login

public boolean login()
              throws LoginException

Specified by:

login in interface LoginModule

Throws:

LoginException

login

protected abstract boolean login(NameCallback nameCb,
