best way to initialize BackingBean?
Hi folks!
What is the best way to initialize BackingBeans?
I would like to get data from a DB everytime before the jsp will be
shown initializing the jsp with this data.
I can't use the constructor initialization cause I need it everytime not
only the first time.
I can't use initialization via managed-property cause the data isn't
static...
Any suggestions?
Thx
Stefan Gesigora

I'm using Shale for this. This is one of the specific things that
Shale is designed to give you. And yes, you can use with either the
RI or MyFaces (basically any JSF implementation.) I use it with
MyFaces of course ;-)
There is a nice overview on the Struts website now
(http://struts.apache.org/shale.) Check out the javadocs as well
since there is some good summary documentation in there as well.

I'm new to JSF, so maybe this isn't best way. But couldn't you do that from
the action that sends you to the page you want to initialize. Have your
action mapped to the method you want to use as initilization method, then
forward to the page.

You might use Shale to do this kind of things.
With Shale, if your beans implement a special interface, several
methods will be called on your bean - one of them before the view is
shown...

Martin
