Subject RE: How to run servlet for every 30 minutes in Tomcat 4.1.30
Date Tue, 21 Dec 2004 16:41:06 GMT
My application has to use the connection pooling of Tomcat to talk to the
database...
and all my Database access classes are deployed om Tomcat...so if i just
write a java standalone command line program,
can i access those connection pooling classes...

Why are you writing a servlet for this?  If the application does not
use any of the services confined to the Servlet API and Tomcat, just
write a stand-alone application and setup up a cron job to run it.
Seems like overkill to me.

like cron to issue a HTTP call to your servlet. I once wrote a shell script
that calls a http address on the local machine but cannot remember how ;) if
you are using oracle then you can setup this timer thread inside the
database itself. don't add a thread into your web application.
