are supported by this application. It consists of Struts based JSP flexible

front end application (rbsinsurance-web-app) enabling different brands to

have different look and feel. This application captures the customer data

and sends it via xml over http to another application (xmlserver), which

then converts the xml data into a String format understandable by the

Mainframe backend and then sends the a CICS request to the mainframe web

backend. The application uses Business Delegate and Service Location

pattern to invoke various services (address validation, rating, saving a

quote, payments, policy purchase etc) to the Mainframe Web backend. The

mainframe response is converted back to xml by the xmlserver and passed on

to rbsinsurance-web-app and subsequently shown to the customer.

ECRM application: This is used to send emails to any customer who has saved

a quote or purchased/ renewed a policy. The email data come from static xml

files and dynamic xml which is loaded onto a queue by mainframe. Various

listeners are configured to listen to the queues. XSL templates are applied

to the xml to generate either text or html emails.
