Architecture of Oracle Self-Service E-Billing Payment
Oracle Self-Service E-Billing Payment is based on J2EE. It uses Servlets and JSPs for the presentation layer and uses Enterprise JavaBeans (EJB) for the business logic layer. It offers the following sets of functions:
- Enrollment functions. To enroll users for both viewing bills and paying bills (payment). Examples of user information include account numbers and email addresses, and examples of payment account information include bank account numbers and credit card accounts.
- Payment functions. To make payments, set up payment reminders and recurring payments, and so on.
- Administration functions. To set up payment jobs, view payment reports and configure Payment Settings.
Figure 10 shows an overview of the J2EE architecture of Oracle Self-Service E-Billing.

In this architecture, the servlet is responsible for user authentication. After authentication, the servlet forwards the request to JSP pages, which do the bulk of the work. The Oracle Self-Service E-Billing Payment user JSP pages can be categorized into two groups:
- Enrollment JSP pages are responsible for Oracle Self-Service E-Billing Payment user enrollment
- Oracle Self-Service E-Billing JSP pages are responsible for core Oracle Self-Service E-Billing Payment functionality: scheduling payment, setting up recurring payment, and so on.
All Oracle Self-Service E-Billing Payment database access is performed through EJB objects. The JSPs and servlets do not access the database directly. The Oracle Self-Service E-Billing payment batch jobs run from the Command Center. For a list and description of Oracle Self-Service E-Billing Payment jobs, see Administration Guide for Oracle Self-Service E-Billing. This chapter assumes that you have installed and configured Oracle Self-Service E-Billing. It also assumes you understand:
- XML structure and syntax
- J2EE: JSP, HTML, Struts and Tiles
