It's not seam related actually but i think here is the best place to ask.

And when i say the database will be changed every year - the idea is every
year to start with a clear for better performance.

If you design your schema properly you probably shouldn't have to do anything
like this. How much data are you talking about?

That is not that many records, depending on what you want to do with them. As
long as they are properly indexed etc and you are not doing any full table
scans that should not be a problem.

I also believe that DAO isn't necessary anymore. But I do believe that some
helper (or service) classes are a good thing.
You would get something like this:
| view layer
| |
| |
| business layer
| | |

Yes, you are probably right. But creating such a view handler would probably be
a lot of work and complicated to build. But I still have the feeling that an
extra layer would be better. But it is a feeling and I can't really rational
base it on anything.
I am playing with Seam now, so I will
So you are saying that I could use the same Action classes to create a non-web
application with? I don't really see that. You already add a lot of annotations
to the Action class to let it communicate with the view, like the @In, @Out,
@DataModel, @DataModelSelection, etc...

1) You can still add layers
2) jpdl pageflows let you remove the pageflow out of the pages.

You could probably create three ejb libraries for layering.
- ejb lib for entities classes
- ejb lib for business classes
- ejb lib JSF action listeners and other web related classes
