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 the StoreBO project


To implement even the most basic business functionality, the domain entities must exist and be available. So, let's create the project StoreBO (BO means Business Objects) that is going to hold the store's entities.

Note

As we're going to use the Java Persistence API (JPA), it's good to know that the default JPA implementation shipped with Oracle WebLogic Server 12c is Oracle TopLink, which is heavily based on EclipseLink. Up until the previous release (11g), the default implementation was Kodo, which Oracle bought along with other BEA products.

The Oracle Enterprise Pack for Eclipse gives us a couple of handy features to create a JPA Project. By selecting this project type, we basically instructed Eclipse to add the JPA facet to the project, enabling features such as a tool to map relational tables to classes.

Tip

Keep in mind that JPA 2.0, which is the layer that enables EJB 3.x persistence features, is not directly linked to Java EE—you can use the persistence...
