Application variables

[Gaelle]

Hello !
I would like to know : what exactly can I store in the application object ? (using application.setAttribute, for example)
I have a Vector that is used by any user of my intranet site, can I store it in the application object so that anyone can access it ?
Then : how long does such an application variable live ? Is it persistent ?

Thanks !
Gaelle.

>> Is it persistent ?

If you mean persistent accross executions of the server, no. You are left to implement that feature yourself.

The "lifetime" of application is for the execution of the web application. In other words it starts the first time a resource within that application is accessed. And is maintained until the application or server in most cases is stopped.

>> what exactly can I store in the application object

public void setAttribute(java.lang.String name,
                         java.lang.Object object)

so any Java Object, yes?
