Application scope variable on startup

Hi,

I have my own ResourceFactory which returns a bean. I configure this
resource factory in tomcat 5.5 context xm file.

I would like to create a application scope variable on tomcat startup
and assign the value from the bean.method().

Is there anyway we can do it using web.xml?

This can eliminate to create JNDI initialContext in every jsp as I
would be dependent on this application scope variable on each page.

Thanks

look into the ServletContextListener class.

http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/ServletContextListener.html

it can be registered to receive events when your application starts and when it ends.

registering it is as simple as placing lines like this in your web.xml file.

<listener>
<listener-class>com.yourpath.YourContextListener</listener-class>
</listener>
