Powerful browser detection and custom JSP tags with Geronimo Use Geronimo and Jetty to create a browser and OS detection scheme Skill Level: Intermediate Daniel Wintschel (
[email protected]) Author and developer Freelance 13 Sep 2005 Learn how to take advantage of Apache Geronimo and Jetty to create a powerful browser and open source detection scheme. In addition to the open source (OS) Geronimo application server, this tutorial shows you how to use freely available JavaScript programs to perform browser and OS detection on the client side. Section 1. Before you start This tutorial is for developers who would like to implement some form of a browser detection API into an application. You can take advantage of Geronimo as the Java™ 2 Platform, Enterprise Edition (J2EE) application server (specifically its use of Jetty as a servlet container) as well as some client-side JavaScript. You'll be developing a few separate Java-based components including a servlet filter and two custom JavaServer Pages (JSP) tags. You'll use Apache Ant as a build tool to build the .war file that you'll deploy to Geronimo, so some familiarity with Ant is handy. You should be familiar with the concepts of filters and JSP tag libraries, and feel comfortable reading Java source code. By the end of this tutorial, you should have an idea of how to develop your own basic servlet filters and JSP tag libraries, and be able to implement a robust browser detection API into a J2EE application with the Apache Geronimo application server.
