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.

Chapter 8. Adding Security

Security is one of the most important aspects of any application, so we dedicated an entire chapter to this topic; even so, it would be presumptuous to say that this chapter covers all details regarding the subject; instead, the approach will be to bring some of the most common situations of security on Java EE and describe how to implement them through Oracle WebLogic features.

We will explore the security concerns associated with the EJB and Web containers of Java EE. In this context, you can specify the security constraints basically in two ways:

  • Declarative: Through the use of descriptors, annotations, and XML files

  • Programmatic: Hardcoded in an application component or Java class

It's also important to clarify some terminology and define what and how some of these terms will be used through this chapter. The most important ones are:

  • Authentication: Authentication is a word that derives from the word genuine or real in Greek, according to Wikipedia. In the Java...
