Reading a file in a loop over VPN...

Hello all:

I need to write a stand alone Java app which will read a file over a VPN 
connection. This is a transaction file which will need to be checked at 
least every 3 seconds for new records.

What I am looking for from the group is any ideas on the best practice of 
writing this. My concern is if I write a while loop to constantly check 
the file, that this will be a drain on resources on the host as well as 
the VPN. Is there a timer API in Java (similar to the CL CMD DELAY) that I 
could use to let the process sleep and wake up every 3 seconds to run the 
I/O.

Thanks in advance for and suggestions.
