A book with Oracle Web Development in the title would be of use
It is important to note that when discussing web applications in this chapter, we are referring to intranet-based or extranet-based web applications. Due to performance, download times, footprint, and JInitiator requirements, it is not practical to deploy these applications in an Internet environment.
In this chapter, Form(s) with a capital F refers to the form(s) developed with the Oracle Forms Builder tool that comes as part of the Oracle Development Suite as opposed to an HTML form, and Report(s) with a capital R refers to reports developed with Oracle

There are many reasons for this (discussed in the appropriate chapters), but some of the
Legacy applications and legacy knowledge.
The move to the Web greatly decreases administration costs, particularly for large installations where many users are spread over a large distance. Keeping the client machines (which probably have different versions of operating systems, different service
Tool feature set incompatibilities and complexity. Oracle Portal has wizards that allow the development of forms and reports, but these Portal components do not have all of the functionality of the respective Oracle Forms and Oracle Reports products. Oracle JDeveloper 10 g allows complete control of all aspects of your application, but has a much higher learning curve.
In Chapter 1, we discussed the different types of Oracle Application Server 10 g installations. You will recall that there were three different types of installations:
J2EE and Web Cache Provides a HyperText Transfer Protocol (HTTP) server and Oracle Application Server Containers for J2EE (OC4J) containers for the deployment of Java applications.
Portal and Wireless Provides all of the components in the J2EE and Web Cache installation plus support for wireless devices and the Oracle Portal environment.
Business Intelligence and Forms Includes support for serving Oracle Forms, Oracle Reports, and Oracle Discoverer workbooks and worksheets over the Web. This chapter focuses on the Business Intelligence and Forms features of Oracle Application Server 10 g .
In Chapter 14). There are many issues when moving these components to the Web, not the least of which is the fundamental architecture change from client/server to web deployment. This chapter addresses the major issues and provides a road map for a seamless transition of Oracle Forms, Reports, and Discoverer workbooks and worksheets to the Web.
