In Detail
With ADF, Oracle gives you the chance to use the powerful tool used by Oracle’s own developers. Modern enterprise applications must be user-friendly, visually attractive, and fast performing. Oracle Fusion Applications are just that; but to get the desired output you need proven methods to use this powerful and flexible tool to achieve success in developing your enterprise applications.
"Developing Web Applications with Oracle ADF Essentials" explains all you need to know in order to build good-looking, user-friendly applications on a completely free technology stack. It explains the highly productive, declarative development approach that will literally have your application running within a few hours, as well as how to use Java to add business logic.
"Developing Web Applications with Oracle ADF Essentials" tells you how to develop and deploy web application applications based on the highly productive and free Oracle ADF Essentials framework. You will first learn how to build business services on top of database tables, and then how to easily build a web application using these services. You will see how to visually design the flow through your application with ADF task flows, and how to use Java programming to implement business logic. Using this book, you can start building and deploying advanced web applications on a robust, free platform quickly.
Towards the end, you will be ready to build real-world ADF Essentials applications and will be able to consider yourself an ADF Essentials journeyman.

Remember to choose SQL92 as the SQL Platform and choose Java as Data Type Map. The SQL Platform setting controls the SQL statements that ADF generates. If you know you'll be using a specific database, you can select it to allow ADF to build optimized SQL for that platform. SQL92 is a standard that is supported by all modern databases, including

Select this node and give it the name RentalUnreturned in the New View Instance field, and then shuttle it to the right.

the lib directory of the GlassFish domain where you want to run ADF Essentials applications. If you performed the installation as described earlier in the chapter, the lib directory will be c:\adfessentials\glassfish3\glassfish\ domains\domain1\lib. Setting the GlassFish JVM parameters Because ADF applications are a bit more memory-hungry than the average JEE application, you will need to change the GlassFish JVM settings.
