  • Javaedge Setup and Installation
    APPENDIX A ■ ■ ■ JavaEdge Setup and Installation Throughout the book, we have used the example application, JavaEdge, to provide a practical demonstration of all the features discussed. In this appendix, we will walk you through setting up the tools and applications required to build and run JavaEdge, as well as take you through the steps needed to get the JavaEdge application running on your platform. Environment Setup Before you can get started with the JavaEdge application, you need to configure your platform to be able to build and run JavaEdge. Specifically, you need to configure Apache Ant in order to build the JavaEdge application and package it up for deployment. In addition, the JavaEdge application is designed to run on a J2EE application server and to use MySQL as the back-end database. You also need to have a current JDK installed; the JavaEdge application relies on JVM version 1.5 or higher, so make sure your JDK is compatible. We haven’t included instruc- tions for this here, since we are certain that you will already have a JDK installed if you are reading this book. However, if you do need to download one, you can find it at http://java. sun.com/j2se/1.5.0/download.jsp. Installing MySQL The JavaEdge application uses MySQL as the data store for all user, story, and comment data. If you don’t already have the MySQL database server, then you need to obtain the version applicable to your platform. You can obtain the latest production binary release of MySQL for your platform at http://www.mysql.com.

  • Apache Geronimo Uncovered a View Through the Eyes of a Websphere Application Server Expert
    Apache Geronimo uncovered A view through the eyes of a WebSphere Application Server expert Skill Level: Intermediate Adam Neat ([email protected]) Author Freelance 16 Aug 2005 Discover the Apache Geronimo application server through the eyes of someone who's used IBM WebSphere® Application Server for many years (along with other commercial J2EE application servers). This tutorial explores the ins and outs of Geronimo, comparing its features and capabilities to those of WebSphere Application Server, and provides insight into how to conceptually architect sharing an application between WebSphere Application Server and Geronimo. Section 1. Before you start This tutorial is for you if you: • Use WebSphere Application Server daily and are interested in understanding more about Geronimo. • Want to gain a comparative groundwork understanding of Geronimo and WebSphere Application Server. • Are considering sharing applications between WebSphere Application Server and Geronimo. • Simply want to learn and understand what other technologies are out there (which I often do). Prerequisites Apache Geronimo uncovered © Copyright IBM Corporation 1994, 2008. All rights reserved. Page 1 of 23 developerWorks® ibm.com/developerWorks To get the most out of this tutorial, you should have a basic familiarity with the IBM WebSphere Application Server product family. You should also posses a general understanding of J2EE terminology and technologies and how they apply to the WebSphere Application Server technology stack. System requirements If you'd like to implement the two technologies included in this tutorial, you'll need the following software and components: • IBM WebSphere Application Server. The version I'm using as a base comparison is IBM WebSphere Application Server, Version 6.0.
