Hello,

I'm thinking about how to access rarely changed data the right way. 

An example: I store categories in the database; they may change once a week.

So normally I would store them in Application Scope, but as I triggered out, 
there is no easy way to invalidate the Application scope - in case of a change 
(only if I call a method to reinitialize (@create) the Component).

Now my second thought was about using Hibernate cache to store the categories 
in Memory. But I don?t really know how to handle the update.

Is there a design pattern for this problem and what is the better approach 
(Application Scope or cache)?

Important is, that the categories are not reloaded every request but that they 
are updated if they were changed.
