It's not out of the question, but it's probably not necessary.

Do you have 10 to 20 application servers? Otherwise I don't understand
how you're getting 300 to 500 connections. Do you have any stats about
how many connections for each database each JBOSS server actually needs?
It seems unusual that it would need more than one or two.
Also, why does the application use 7 different databases?
