Re: Timing service in Tomcat
Sasha, We wanted to reuse our business java code for our batch runs so we implemented a cron job with issued a lynx command such as lynx http://webxx/servlet/batch?batch=2&date=05/13/04. We run our production environment in linux so lynx was available by default.

RE: Timing service in Tomcat
Hi, Quartz and Flex are good. They may be overkill though, depending on your needs. Java.util.Timer is perfectly fine as well. Where to initialize also depends on your needs, but a Servlet's init or a ServletContextListener's contextInitialized are two candidate locations.

We're using this in part with some in-house stuff. It works well; I actually can't think of any other open -source component that's comparable. Or is this kind of stuff home-grown right now (java.util.Timer, etc.)? If you've got your own timer, where do you initialize it (like in a servlet's init() or a context listener)? For the custom stuff, we have a seperate servlet for each job/task (java.util.Timer), and a reference is stored to them in the application context, for admin purposes. We start each Timer from a single Startup servlet, which gets the majority of its parameters from the web.xml file (ideally, i'd rather this was seperated).

Timing service in Tomcat
I'm wondering what people are doing to schedule/execute tasks in Tomcat... Is there any built-in timing services in Tomcat? Are people using external operating system tools like cron to invoke a class, or hit a servlet? Is anyone using a good 3rd party scheduling framework? Or is this kind of stuff home-grown right now (java.util.Timer, etc.)? If you've got your own timer, where do you initialize it (like in a servlet's init() or a context listener)?
