here is a little java applicaiton I wrote -- if you need the compiled files
I can send them - email me rvince99 at hotmail dot com. Anyhow, you merely
specify how many seconds you want to wait before re-invoking something. For
instance, if I want to execute test.php and it is in c:\x, my command would
be:
c:\php\php.exe c:\x\test.php
I wrote this so that php scripts, java pplications, etc., can be invoked
every X seconds without regard to platform.
