Specific method for bean JSF!

[Francisco Neto]

Hi guys,

I'm new developing with JSF and I want to know if there is a way I could write a method that will be called every time a request comes in. My bean is in the session scope! So, I can't write this code in the constructor because it will be called only once.

Turn the bean scope to request is not a option! I need the bean for the session.

There's another approach I can use to do this?!


Thanks!
Francisco.

Hi Francisco,

Following is a not so neat solution (i am looking for some extension point in framework but haven't found it yet).

Request scoped values can be kept in a different bean and request specific logic can be invoked in Constructor or last setter of the bean. This bean cannot be set as a managed property in session scoped bean and hence will have to looked up in session bean as

FacesContext.getCurrentInstance().getApplication().createValueBinding("#{<request scoped bean name>}").getValue(FacesContext.getCurrentInstance());

Hope it helps.

Warm Regards
Ravindra

Just for info, this is what the Aspect-Oriented Programming people call a "cross-cutting" concern. I haven't tried AOP+JSF, however, except to the degree that the Spring framework helps out my data persistence.

Make your own action listener and configure JSF to use it as the default action listener.

Inside the listener check the bean name and through reflection (or cast it) call the method you want.

Hi,

Could you not use the shale framework?

So you could use the view controller as the base controller of your session beans and then make use of the prerender or init methods?
