JBoss Tools 3 Developers Guide

Overview of this book

JBoss Tools consist of the best Java frameworks and technologies placed together under the same "roof". Discovering JBoss Tools is like exploring a cave; at first everything seems unknown and complicated, but once you become familiar with the main features of the Tools, you will start to feel at home. This is the first book in the market on JBoss Tools, waiting to assist you to throw away all the tiny, dedicated tools you have used earlier, thus helping you to reduce the time you spend on developing a Java application. This book will explore the tools that will help you to build Hibernate, Seam, JSF, Struts, Web Services, jBPM, ESB, and so on and show you how to use them through screenshots, examples, and source code. JBoss Tools comes with a set of dedicated wizards, generators, editors, reverse engineering capabilities, configuration files, templates, syntax highlighting, and more for each of these technologies. Just choose the technologies, and JBoss Tools will glue them together in amazing Java web applications. This book will show you how to develop a set of Java projects using a variety of technologies and scenarios. Everything is described through JBoss Tools "eyes". After we settle the project (or scenario) that will be developed, we configure the proper environment for the current tool (the selected projects cover the main components of a web application, with regard to the backstage technology). We continue by exploring the tool to accomplish our tasks and develop the project's components. A cocktail of images, theoretical aspects, source code, and step-by-step examples will offer you a complete insight into every tool. At the end, we deploy and test the project. In addition, every chapter is rich with pure notions about the underlying technology, which will initiate into you or remind you of the basic aspects of it. It will also show you complete and functional applications, and get you familiar with the main aspects of every tool. By the end you will have enough information to successfully handle your own projects with JBoss Tools.

Preface

Adding a JSP portlet in JBoss Portal


In this section, we will develop a JSP portlet that will act as a temperature converter. It will convert from Celsius degrees to Fahrenheit and vice versa. Among the facilities, it will contain a view, an edit and a help page, it will allow users to customize the default conversion, and it will provide a data vaildator. In the following screenshot, you can see what we will obtain at the end of this section:

Before developing our JSP portlet, create a Dynamic Web Project stub and name it myJSPPortlets. Also, add the JBoss Portlet facet to it. You should be able to successfully accomplish these two tasks based on previous sections.

Creating a JSP Portlet

Practically, a JSP portlet is a Java portlet with JSP capabilities. This means that we can generate the JSP portlet's artifacts by following the same scenario used to generate the HelloWorldPortlet portlet. Nevertheless, this time we will seriously alter the default settings of the Java Portlet wizard, as...
