final class cann't be a seam component?

[wuhaixing]

I used to create a final class to provide some constants list for other classes,when I try this in the seam,the jboss 4.2.1 tell me cann't creat the component.
Is it because it's a final class?If so,what should I do the same thing in the seam as before?

[wuhaixing]

I found the reason why I cann't create the component:
@PersistenceContext may only be used on session bean or message driven bean components

so,what should I do to the common constant lists?

I found the same thing I want in the dvdstore sample,ProcessDefinitionSwitcher
Can I store the list in the db instead of a final String[] list in the code?

Yes, it would be easy to do that.
