protected final String getDefaultUserName() 
{
	return requestingUserName;
}

 protected PasswordAuthentication getPasswordAuthentication() 
{
	return null;
}

Called when password authentication is needed. Subclasses should override the default implementation, which returns null.

Note that if this method uses a dialog to prompt the user for this information, the dialog needs to block until the user supplies the information. This method can not simply return after showing the dialog.

 protected final int getRequestingPort() 
{
	return requestingPort;
}

 protected final String getRequestingPrompt() 
{
	return requestingPrompt;
}

 protected final String getRequestingProtocol() 
{
	return requestingProtocol;
}

Give the protocol that's requesting the connection. Often this will be based on a URLName.

 protected final InetAddress getRequestingSite() 
{
	return requestingSite;
}

 final PasswordAuthentication requestPasswordAuthentication(InetAddress addr,
    int port,
    String protocol,
    String prompt,
    String defaultUserName) 
{
	reset();
	requestingSite = addr;
	requestingPort = port;
	requestingProtocol = protocol;
	requestingPrompt = prompt;
	requestingUserName = defaultUserName;
	return getPasswordAuthentication();
}

Ask the authenticator for a password.
