Getting Started with Oracle WebLogic Server 12c: Developer's Guide

Overview of this book

Oracle WebLogic server has long been the most important, and most innovative, application server on the market. The updates in the 12c release have seen changes to the Java EE runtime and JDK version, providing developers and administrators more powerful and feature-packed functionalities. Getting Started with Oracle WebLogic Server 12c: Developer's Guide provides a practical, hands-on, introduction to the application server, helping beginners and intermediate users alike get up to speed with Java EE development, using the Oracle application server. Starting with an overview of the new features of JDK 7 and Java EE 6, Getting Started with Oracle WebLogic Server 12c quickly moves on to showing you how to set up a WebLogic development environment, by creating a domain and setting it up to deploy the application. Once set up, we then explain how to use the key components of WebLogic Server, showing you how to apply them using a sample application that is continually developed throughout the chapters. On the way, we'll also be exploring Java EE 6 features such as context injection, persistence layer and transactions. After the application has been built, you will then learn how to tune its performance with some expert WebLogic Server tips.

Creating Theater entities


In Chapter 3, Java EE Basics – Persistence, Query, and Presentation, we have already created a JPA project that has entities from the Store module. Now we need to create a similar project for the Theater module, mapping entities of the corresponding database schema. We're going to do it using a few other concepts of Java Persistence API (JPA). Let's get started.

Note

Before proceeding, make sure you have already loaded the tables into the databases and configured OEPE's (Eclipse) connection to MySQL. These procedures are explained in Chapter 2, Setting Up the Environment.

  1. In Eclipse, create a new JPA project and perform the following steps:

    1. Enter TheaterBO as the Project name.

    2. Remember to set the Target runtime to point to your WebLogic 12c Runtime configuration.

    3. At the JPA Facet configuration page, select the same JPA library and implementation you already used in Chapter 3, Java EE Basics – Persistence, Query, and Presentation—that would be EclipseLink 2.4.x/2.5.x...
