If all of your logic is embedded in servlets, and you just want to call one of
them, a stand-alone application can fit the need pretty nicely. Consider the
following thoughts:
* The stand alone application can pretend to be a browser
by using the URLConnection class to issue a request to your
servlet's URI. The servlet doesn't have to know that it was
called from a program instead of by a user.
* See the networking trail in the Java Language Tutorial
(http://java.sun.com/docs/books/tutorial) for example code
using this class.
* To schedule when this application is called, look at using the
scheduling facilities already provided by your operating system,
if any -- such as "cron" on Unix-based systems. Don't bother
to write system-level software like this if it already exists.
