Re: Best practice?

Bj�rn,

it is now worth to look at Shale.

Shale provides an interface that each backing bean *could* implement
it provides a init() method for initializing stuff like you want.
(see: http://people.apache.org/~craigmcc/shale-core-javadocs/org/apache/shale/ViewController.html)

There is use case app, that shows how to use Shale. In that you see, that there is an abstract BaseBackingBean that implements the interface. all your backing beans extend that base backing bean. Since JSF uses POJO you are free to integrate each framework you like.

The sample (use case sample) also provides DAO access for backing beans.

Look at:
http://wiki.apache.org/struts/StrutsShale

Shale is a framework by Craig McClanahan (ex JSF EG lead) under the umbrella of Apache Struts. It relies only on JSF and not on *legacy* Struts API

HTH,
Matthias
