[redhat-ccm-list] Notification Engine

[Jun Yamog]

Hi David,

There are different ways of doing this.  One way to extend

com.arsdigita.notification.BaseSubscription.

Once you have created one, just reuse it.  Just pass a ThreadedMessage
to sendNofication(); most likely in your situation the ThreadedMessage
contains the news on your site.  The notification sweeper should pick it
up during its scheduled run and email it.

Set your enterprise.init params

init com.arsdigita.notification.Initializer { 
    RequestManagerDelay  = 60; // in seconds
    RequestManagerPeriod = 60; // in seconds
    SimpleQueueDelay     = 60; // in seconds
    SimpleQueuePeriod    = 60; // in seconds
    DigestQueueDelay     = 60; // in seconds
    DigestQueuePeriod    = 60; // in seconds
}

BTW don't use those values.  Since I use it for development I wanted
quick results.  So just a minute of wait time.

Another way is just com.arsdigita.mail.Mail.  But then this is more
crude.  But in our case we used a mix of this and notification.  We
actually didn't use notification for the requirement you have given as
an example because.  Each letter to the user was custom made... each
letter maybe different from one user to another.  Also included their
names and other info on the body.
