RE: [JBoss-user] How to register a class as a startup class in JBOSS3

[Saroj K. <kum...@wi...>]

How do we use a mbean? Any starting points? I am new to JBOSS. Any help
would be more than welcome.

Thanks,
Saroj

You could use an mbean for that purpose which would have the additional
advantage of being reinitializable when you cycle your application and
configurable from any (RMI/HTML/whatever) JXM-Adapter.

Statics are poo-poo, IMHO.

There is a generic way to do this with web applications in the 2.2=20
servlet spec and even a better way in 2.3.

In 2.2, you can just have a servlet that calls your initializer in it's=20
init() method.  Then, in web.xml, define the load-on-startup element.=20
That way, when your web app comes up, you get called.  You can also call

a clean-up class in the servlet's destroy() method.

Now, in servlet 2.3, you can define a ServletContextListener (a servlet=20
context is basically your web app) in the web.xml.  You will get=20
notified via the contextInitialized and contextDestroyed methods.

Granted, each of these methods mean assumes you've got a web tier.  Even

if you don't, it's not a horrible thing to just through your ejb jars in

an ear along with a tiny war who's only job is to initialize some stuff.

Now, if you just wanted to now about startup/shutdown classes outside of

your app and specific to jboss, I don't know.

Hope this helps,
David
