Hi Alexander!
I just don't exactly know what you mean.
In my JSF there should be a meta tag, that refreshes the page only one time
depending on a session attribute?
I don't know how to do that the connection will be build at first, when the
refresh starts (when the page will be rendered the second time) and not when
the page will be rendered the first time?
Regards,
Andy

Hi Andy
Have you thought about using the refresh-meta-tag?
You could render the page on first visit with a refresh header set to 1 second.
The page would be rendered reading --- please wait --- and in the background
initiate
a new request which then would build the connection, and render a new page...
A flag in the session could signal to your code whether the redirection is
needed or not.
Advantages I see:
- standard request-processing
- the user would see the browser activity and could conclude: ok, something is
being
processed

Hi Mike!
I like the idea with the Servlet Listener,but I see one problem:
The database connection is already openened when the Application Server is
started
-So could there be a problem with database connection timeouts? What happens,
when the database returns a timeout.
-If no timeout happens, isn't it a bad approach to let the connection open all
the time, because database connection are expensive as long as I know?
What do you think about my thoughts?
Regards
Andy

Andy,
There's many ways to do this.
Some ways you could do it:
1) Use the Shale ViewController stuff to define your backing bean to
be the controlling bean for your page. It'd be able to receive events
like pre-render and post-render.
2) Create a phase listener that ran at pre-render and post-render phase.
3) Use a servlet filter -- this is how I manage my database
connections, but I have need for my database connection to be active
at all phases of JSF.

Hi All!
How can I execute a method from a backing bean AUTOMATICALLY after a page
has been loaded and shown to the user?
My exactly problem is the following:
When the user opens the first page, this page should be shown normally (and
quickly) to the user. In the background the connection to the database
should be build (automatically, no button should be pressed) --I use
Hibernate and the first connection (building of connection pool) takes some
seconds, so this should be done in background, but the user should already
see something in his browser (with an info, that the connection to the
database is just built)
Is there a possibility to do that?
Thx
Regards
Andy
