All Implemented Interfaces:

Disposable, Component, Configurable, LogEnabled, Serviceable, ThreadSafe, Action

public class DatabaseCookieAuthenticatorAction
extends AbstractDatabaseAction
implements ThreadSafe

This action is used to authenticate user by comparing several cookie values (username, password) with the values in database. The description of the process is given via external xml description file simiar to the one used for all actions derived from AbstractDatabaseAction.

 <root>
         <connection>personnel</connection>
         <table name="users_table>
                 <select dbcol="username" cookie-name="username"
                 to-session="username"/>
                 <select dbcol="password" cookie-name="password"
                 nullable="yes"/>
                 <select dbcol="role" to-session="role" type="string"/>
                 <select dbcol="skin" to-session="skin" type="string"/>
         </table>
 </root>
 

The values specified via "cookie-name" describe the name of the cookie, "dbcol" indicates matching database column, "nullable" means that cookie-name which is null or empty will not be included in the WHERE clause. This way you can enable accounts with empty passwords, etc. "to-session" attribute indicates under which name the value obtained from database should be stored in the session. Of course new session is created when authorization is successfull. The "type" attribute can be either string, long or double and alters the type of object stored in session. Additionally all parameters that are propagated to the session are made available to the sitemap via {name} expression. If there is no need to touch the session object, providing just one-time verification, you can specify action parameter "create-session" to "no" or "false". No values are then propagated to the sesion and session object is not verified. If you want to append attributes to the session without creating a new one, specify action parameter "append-session" to "yes" or "true".
