5. The Transfer EJB uses two entity EJBs: CustomerAccount and
BranchAccount to make the transfer between accounts and update the
back-end system, which is a database in our case.
6. After the transfer, the Transfer servlet sends the response back to the client
using a JSP.
The next process depicted in Figure A-3 is a transfer between two branches, and
JMS messaging is used to process the request.
The first four steps are the same as with the “customer transfer”.

The process flows as described below:
1. User selects the customer transfer link on the main page (index.html) of the
