    • initialize

      public void initialize​(Engine engine, java.util.Properties props)

      Initializes this Engine component. Note that the engine is not fully initialized at this point, so don't do anything fancy here - use lazy init, if you have to.
       

      Specified by:
      initialize in interface Initializable
      Parameters:
      engine - Engine performing the initialization.
      props - Properties for setup.

    • getUserDatabase

      public UserDatabase getUserDatabase()
      Returns the UserDatabase employed by this Engine. The UserDatabase is lazily initialized by this method, if it does not exist yet. If the initialization fails, this method will use the inner class DummyUserDatabase as a default (which is enough to get JSPWiki running).
      Specified by:
      getUserDatabase in interface UserManager
      Returns:
      the dummy user database

    • getUserProfile

      public UserProfile getUserProfile​(Session session)

      Retrieves the UserProfile for the user in a session. If the user is authenticated, the UserProfile returned will be the one stored in the user database; if one does not exist, a new one will be initialized and returned. If the user is anonymous or asserted, the UserProfile will always be newly initialized to prevent spoofing of identities. If a UserProfile needs to be initialized, its UserProfile.isNew() method will return true, and its login name will will be set automatically if the user is authenticated. Note that this method does not modify the retrieved (or newly created) profile otherwise; other fields in the user profile may be null.

      If a new UserProfile was created, but its UserProfile.isNew() method returns false, this method throws an IllegalStateException. This is meant as a quality check for UserDatabase providers; it should only be thrown if the implementation is faulty.

      Specified by:
      getUserProfile in interface UserManager
      Parameters:
      session - the session, which may not be null
      Returns:
      the user's profile, which will be newly initialized if the user is anonymous or asserted, or if the user cannot be found in the user database

    • setUserProfile

      public void setUserProfile​(Context context, UserProfile profile) throws DuplicateUserException, WikiException

      Saves the UserProfile for the user in a wiki session. This method verifies that a user profile to be saved doesn't collide with existing profiles; that is, the login name or full name is already used by another profile. If the profile collides, a DuplicateUserException is thrown. After saving the profile, the user database changes are committed, and the user's credential set is refreshed; if custom authentication is used, this means the user will be automatically be logged in.

      When the user's profile is saved successfully, this method fires a WikiSecurityEvent.PROFILE_SAVE event with the Session as the source and the UserProfile as target. For existing profiles, if the user's full name changes, this method also fires a "name changed" event (WikiSecurityEvent.PROFILE_NAME_CHANGED) with the Session as the source and an array containing the old and new UserProfiles, respectively. The NAME_CHANGED event allows the GroupManager and PageManager can change group memberships and ACLs if needed.

      Note that Sessions normally attach event listeners to the UserManager, so changes to the profile will automatically cause the correct Principals to be reloaded into the current Session's Subject.

      Specified by:
      setUserProfile in interface UserManager
      Parameters:
      context - the wiki context, which may not be null
      profile - the user profile, which may not be null
      Throws:
      DuplicateUserException - if the proposed profile's login name or full name collides with another
      WikiException - if the save fails for some reason. If the current user does not have permission to save the profile, this will be a WikiSecurityException; if if the user profile must be approved before it can be saved, it will be a DecisionRequiredException. All other WikiException indicate a condition that is not normal is probably due to mis-configuration

    • startUserProfileCreationWorkflow

      public void startUserProfileCreationWorkflow​(Context context, UserProfile profile) throws WikiException
      Specified by:
      startUserProfileCreationWorkflow in interface UserManager
      Throws:
      WikiException

    • parseProfile

      public UserProfile parseProfile​(Context context)

      Extracts user profile parameters from the HTTP request and populates a UserProfile with them. The UserProfile will either be a copy of the user's existing profile (if one can be found), or a new profile (if not). The rules for populating the profile as as follows:

      • If the email or password parameter values differ from those in the existing profile, the passed parameters override the old values.
      • For new profiles, the user-supplied fullname parameter is always used; for existing profiles the existing value is used, and whatever value the user supplied is discarded. The wiki name is automatically computed by taking the full name and extracting all whitespace.
      • In all cases, the created/last modified timestamps of the user's existing or new profile always override whatever values the user supplied.
      • If container authentication is used, the login name property of the profile is set to the name of Session.getLoginPrincipal(). Otherwise, the value of the loginname parameter is used.
      Specified by:
      parseProfile in interface UserManager
      Parameters:
      context - the current wiki context
      Returns:
      a new, populated user profile

    • validateProfile

      public void validateProfile​(Context context, UserProfile profile)
      Validates a user profile, and appends any errors to the session errors list. If the profile is new, the password will be checked to make sure it isn't null. Otherwise, the password is checked for length and that it matches the value of the 'password2' HTTP parameter. Note that we have a special case when container-managed authentication is used and the user is not authenticated; this will always cause validation to fail. Any validation errors are added to the wiki session's messages collection (see Session.getMessages().
      Specified by:
      validateProfile in interface UserManager
      Parameters:
      context - the current wiki context
      profile - the supplied UserProfile

    • listWikiNames

      public java.security.Principal[] listWikiNames() throws WikiSecurityException
      A helper method for returning all of the known WikiNames in this system.

      listWikiNames in interface UserManager
      Returns:
      An Array of Principals
      Throws:
      WikiSecurityException - If for reason the names cannot be fetched
