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.

The purpose of the book is to refresh or introduce Java EE 6 concepts implemented by WebLogic Server 12c, by showing how to apply them in a real-world scenario, presenting product-specific features that would be relevant to make things easier and more productive, both during design and runtime.

So, we covered topics such as persistence configuration and usage, the mechanics of sending and receiving asynchronous messages by using JMS and remote clients, how to create and use events, interceptors, and validations rules, how to secure an application, the main techniques used to scale up your code to process larger quantities of requests, and how to use communication channels such as...
