public class JXLoginPane
extends JXPanel

JXLoginPane is a specialized JPanel that implements a Login dialog with support for saving passwords supplied for future use in a secure manner. LoginService is invoked to perform authentication and optional PasswordStore can be provided to store the user login information.

In order to perform the authentication, JXLoginPane calls the authenticate method of the LoginService . In order to perform the persistence of the password, JXLoginPane calls the put method of the PasswordStore object that is supplied. If the PasswordStore is null, then the password is not saved. Similarly, if a PasswordStore is supplied and the password is null, then the PasswordStore will be queried for the password using the get method. Example:

         final JXLoginPane panel = new JXLoginPane(new LoginService() {
                      public boolean authenticate(String name, char[] password,
                                      String server) throws Exception {
                              // perform authentication and return true on success.
                              return false;
                      }});
      final JFrame frame = JXLoginPane.showLoginFrame(panel);

Constructor Detail

JXLoginPane

public JXLoginPane()

Create a JXLoginPane that always accepts the user, never stores passwords or user ids, and has no target servers.

This constructor should NOT be used in a real application. It is provided for compliance to the bean specification and for use with visual editors.

JXLoginPane

public JXLoginPane(LoginService service)

Create a JXLoginPane with the specified LoginService that does not store user ids or passwords and has no target servers.

Parameters:

service - the LoginService to use for logging in

JXLoginPane

public JXLoginPane(LoginService service,
                   PasswordStore passwordStore,
                   UserNameStore userStore)

Create a JXLoginPane with the specified LoginService, PasswordStore, and UserNameStore, but without a server list.

If you do not want to store passwords or user ids, those parameters can be null. SaveMode is autoconfigured from passed in store parameters.

Parameters:

service - the LoginService to use for logging in

passwordStore - the PasswordStore to use for storing password information

userStore - the UserNameStore to use for storing user information

JXLoginPane

public JXLoginPane(LoginService service,
                   PasswordStore passwordStore,
                   UserNameStore userStore,
                   List<String> servers)

Create a JXLoginPane with the specified LoginService, PasswordStore, UserNameStore, and server list.

If you do not want to store passwords or user ids, those parameters can be null. SaveMode is autoconfigured from passed in store parameters.

Setting the server list to null will unset all of the servers. The server list is guaranteed to be non-null.

Parameters:

service - the LoginService to use for logging in

passwordStore - the PasswordStore to use for storing password information

userStore - the UserNameStore to use for storing user information

servers - a list of servers to authenticate against

Method Detail

isCapsLockOn

public boolean isCapsLockOn()

Gets current state of the caps lock as seen by the login panel. The state seen by the login panel and therefore returned by this method can be delayed in comparison to the real caps lock state and displayed by the keyboard light. This is usually the case when component or its text fields are not focused.

Returns:

True when caps lock is on, false otherwise. Returns always false when isCapsLockDetectionSupported() returns false.

isCapsLockDetectionSupported

public boolean isCapsLockDetectionSupported()

Check current state of the caps lock state detection. Note that the value can change after component have been made visible. Due to current problems in locking key state detection by core java detection of the changes in caps lock can be always reliably determined. When component can't guarantee reliable detection it will switch it off. This is usually the case for unsigned applets and webstart invoked application. Since your users are going to pass their password in the component you should always sign it when distributing application over the network.

Returns:

True if changes in caps lock state can be monitored by the component, false otherwise.
