public abstract class LoginService
extends AbstractBean

LoginService is the abstract base class for all classes implementing a login mechanism. It allows you to customize the threading behaviour used to perform the login. Subclasses need to override the authenticate method. Subclasses may implement the getUserRoles() method to return a meaningful value this method will be called once upon a successful login to determine the user roles. It is not defined as abstract to simplify the task of implementing a login service for those who do not require this functionality.

Method Details

authenticate

public abstract boolean authenticate(String name,
 char[] password,
 String server)
                              throws Exception

This method is intended to be implemented by clients wishing to authenticate a user with a given password. Clients should implement the authentication in a manner that the authentication can be cancelled at any time.

Parameters:

name - username

password - password

server - server (optional)

Returns:

true on authentication success

Throws:

Exception - TODO explain

getUserRoles

public String[] getUserRoles()

Called immediately after a successful authentication. This method should return an array of user roles or null if role based permissions are not used.

Returns:

per default null

cancelAuthentication

public void cancelAuthentication()

Notifies the LoginService that an already running authentication request should be cancelled. This method is intended to be used by clients who want to provide user with control over cancelling a long running authentication request.

startAuthentication

public void startAuthentication(String user,
 char[] password,
 String server)
                         throws Exception

This method starts the authentication process and is either synchronous or asynchronous based on the synchronous property

Parameters:

user - user

password - password

server - server

Throws:

Exception - TODO explain

getSynchronous

public boolean getSynchronous()

Get the synchronous property

Returns:

the synchronous property

setSynchronous

public void setSynchronous(boolean synchronous)

Sets the synchronous property

Parameters:

synchronous - synchronous property

addLoginListener

public void addLoginListener(LoginListener listener)

Adds a LoginListener to the list of listeners

Parameters:

listener - listener

removeLoginListener

public void removeLoginListener(LoginListener listener)

Removes a LoginListener from the list of listeners

Parameters:

listener - listener

getServer

public String getServer()

Returns:

Returns the server.

setServer

public void setServer(String server)

Parameters:

server - The server to set.
