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.

Setting up a WebLogic domain


As you may know, after finishing the installation of Oracle WebLogic Server, you have the necessary binaries to start a container, but there is no configured server to deploy your code yet (unless you installed the samples, but we're not going to use them). To accomplish this, you have to create a domain consisting of one or more server instances. Your code runs on these instances.

We're going to use a basic domain template, consisting of just one instance, since we don't have any scalability or high availability requirements for the time being.

Tip

Concepts related to how to configure an Oracle WebLogic Server environment—domains, clusters, machines, and so on—are covered in Chapter 10, Scaling Up the Application. For now, we only have to know that we need an instance to run the projects on, and it is part of a domain, which is the component that OEPE links to.

To create it, follow the ensuing steps:

  1. Start the Configuration Wizard script, config.cmd (Windows) or...
