First you need an infinite loop:
while ( true )
{
doYorStuff();
// wait
try { Thread.sleep(1800000); }
catch ( InterruptedException e ) { }
}
Second, use URLConnection to retreive your data. Planty of examples out there

Hello Guys:
I'm trying to implement servlet invocation after
certain time period automatically.
The servlet will connect to a database, retrieve the
data and then download it into a flat file. I want
this process to be repeated after every 30 minutes.
Any brain dump or pointers about how to implement this
is appreciated.
Thanks,
Mub
