If I have a field like Customer Number that has to be validated against a large SQL table (10,000 entries), can the validation be done on a field basis and on the server? (ie. dynamically & quickly)
This is a common requirement for an Order Entry type application.
Ideally, I would like to have a dynamically created list of Customer codes that the user could select.. even better would be the ability to press an icon/button and switch to the Customer table for data-entry..
I develop business applications where 90% of the data-entry consists of direct entry into various SQL tables. Validation of the data is very important.
I'm not used jBoss yet, and I want to make sure that it can do what I want before jumping in..

That is not the quesstion to ask.
You have to model the things you want to persist in a EntityEJB.
And have all the bussiness logic in that class as well.
(You should not talk directly to the database.)
