U can use Helper Class which could be a Bean to return the Values(details)
about the Number.And then copy the Helper properties to the associated form.
If you dont find the Number in the database return an empty form bean to be
populated.

With this you can have a DAO class doing all the Database related
operations. Then if you like you can have values in session.Remember to
clear you session when you are done.
