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.

Summary


In this chapter, we checked out some of the resources provided by the presentation layer of WebLogic Server, exploring how to create composite components that can be reused by the application, how to dynamically instantiate servlets, some details about the way the servlet engine works, how to process requests asynchronously, and how to create and test a WebSocket component.

In the next chapter, we will see how to configure an application so it can scale up and support heavy loads. Some of the features we will explore are:

  • Configuration of a WebLogic cluster to scale up applications

  • Creating a singleton service

  • Session Replication with Oracle Coherence (Coherence*Web)

  • Using Oracle Coherence along with JPA to speed up access to entities
