I will try to give insight into that page.
That page would have
BusinessType (Kind of business the company does)Customer List (List of customers who offer that kind of business ) - Drop DownCustomer Contact (List of contact person for this customer depends of customer selection) - Drop Down againand some other information again one to one per business type.
So the data/page would look like

There might be hundreds of companies who offer Bonding Agent(It's industry term and hard to explain. sorry!) business so that's why customer drop down may contains thousand of entries. But the customer contact would not be more than 10 generally.
And one good news is we are already using Spring MVC + DWR. Spring gives good integration with DWR.
