Hello Java experts

For application there are some cross cutting requirements in area of Alloed values .
1. List of allowed values for a drop down.
2. Core value to system value conversion.
3. Possible values for an edit control.
4. Allowed values keyed by other values . For example list of states keyed by country.
and so on .

These are pretty common problems and I have not seen any pattern or open source implementation around this .

Can you guys share your thoughts on this ? Are there any patterns ? Are there any open source implementation to address this issue ?

Thanks
Sunil

Hi Guys

I was reading all comments regarding the issue about sequence diagram for two different clients.
I am trying to understand why would someone implement two different clients ?
Why not travel agent use the same interface as the customer ?
Travel agents can communicate to the same web server through different ports. for both the controler thats the servlet can run on the same application server as the business tier and hence can use the local interface of the stateull session bean .
Am I missing anything ? Any thoughts

Thanks
