public class WOServletSessionStore

extends WOSessionStore

This is a subclass of WOSessionStore, and is intended to replace the WOServerSessionStore subclass. The intention is that WOSessions will be piggybacked on HttpSession objects from the JSP/Servlet world. As they expire, so will the WOSessions. If they are serialized and moved to another container, the WOSession should follow it -- however, this functionality may not be completed. Because of this, this session store does not actually store sessions. Instead, it knows how to add/remove sessions to/from existing JSP sessions. One consequence is that the WOSessionTimeout setting is no longer applicable, as the JSP session setting will be used instead.

Constructor Summary

WOServletSessionStore()

Method Detail

removeSessionWithID

public WOSession removeSessionWithID(String sessionID)

Description copied from class: WOSessionStore

Removes a WOSession instance from storage in order to make it eligible for garbage collection.

This method should be implemented by concrete WOSessionStore subclasses.

Overrides:

removeSessionWithID in class WOSessionStore

Following copied from class: com.webobjects.appserver.WOSessionStore

Parameters:

sessionID - the session id associated with the WOSession to be removed

Returns:

the specified WOSession if found; null otherwise

restoreSessionWithID

public WOSession restoreSessionWithID(String sessionID,
                                      WORequest woRequest)

Description copied from class: WOSessionStore

Restores a WOSession associated with sessionID from storage. This method is called from checkOutSessionWithID and is to be implemented by a concrete WOSessionStore subclass. The subclass is free to decide on the kind of suitable storage and the algorithm for restoration.

The default implementation does nothing.

Overrides:

restoreSessionWithID in class WOSessionStore

Following copied from class: com.webobjects.appserver.WOSessionStore

Parameters:

sessionID - the session id associated with the WOSession to be restored

aRequest - the input HTTP request for session restoration

Returns:

a restored WOSession if found; null otherwise

WOSessionStore.checkOutSessionWithID(String, WORequest)

saveSessionForContext

public void saveSessionForContext(WOContext context)

Description copied from class: WOSessionStore

Saves the current WOSession in context into storage. This method is called from checkInSessionForContext and is to implemented by a concrete WOSessionStore subclass. The subclass is free to decided on the kind of suitable storage and the algorithm for saving.

The default implementation does nothing.

Overrides:

saveSessionForContext in class WOSessionStore

Following copied from class: com.webobjects.appserver.WOSessionStore

Parameters:

context - the WOContext to retrieve the current session to be saved

See Also:

WOSessionStore.checkInSessionForContext(WOContext)

woSessionFromHttpSession

public static WOSession woSessionFromHttpSession(com.webobjects.jspservlet.HttpSession anHttpSession)

Returns the WOSession associated with anHttpSession. If anHttpSession is null, or has no associated WOSession, this method returns null.

Parameters:

anHttpSession - the HttpSession object (this is the JSP session object).
