It is certainly possible to use the servlet interfaces in order to
allow automated execution using this method. This seems a little "hacky"
to me though. Could open up secutity problems too.
I would suggest that the best place for this type of functionality
is either in the database since it is a database function, or using a
standalone java application & some scheduler, like cron.
For the first situation, look into whether or not your database
supports triggers and events. Makes things like this easier. If you opt
for the second, which can be much more straight forward if you're not a DB
jockey, look into which functions are common in you code and abstract them
into a parent class. This should allow you to avoid copying too much
code.
