Apache Geronimo 2.1: Quick Reference

Overview of this book

Apache Geronimo is a robust, scalable, secure, and high-performing application server. But like all application servers, this power comes with a steep learning curve. This book can help you save your time and get working with Geronimo in matter of a few hours. This book is a quick-reference guide to Apache Geronimo that mitigates the starting pains that most developers have when they migrate to a new Application Server. It will help you to extend and amplify your existing development skills, empowering you to build new types of applications regardless of the platform or browser. The book will introduce you to the exciting features of Apache Geronimo Application Server. You will see how easily you can develop and deploy Java EE 5 applications on Geronimo. It covers everything from downloading the server to customizing it using custom GBeans. By following the practical examples in this book, you will be able to develop applications quickly using Geronimo Eclipse Plugin. The book covers Geronimo internals in detail, which helps you write custom services on Geronimo. Also, it helps you to gain a deep understanding of Geronimo plugin architecture and teaches you to extend your server functionality via plugins. By the end of the book, you will develop proficiency in Geronimo and Java EE 5 application development.

Clustered Helloworld-cluster application

We will now look at the configuration needed so that the two instances of the helloworld-cluster application available at http://localhost:8080/helloworld-cluster/ and http://localhost:8090/helloworld-cluster/ are served as one logical application, by using Apache web server, the mod_jk module, and AJP connectors in Geronimo.

Updating workers.properties

To use the server instance inst2 with mod_jk, we will need to create another worker similar to geronimo_ajp13 in workers.properties. This second worker will point to the AJP connector in inst2. The configuration is as given below: 

worker.list=geronimo_inst2_ajp13
worker.geronimo_inst2_ajp13.port=8019
worker.geronimo_inst2_ajp13.host=localhost
worker.geronimo_inst2_ajp13.type=ajp13

Add this configuration to workers.properties.

The two workers geronimo_ajp13 and geronimo_inst2_ajp13 are of type ajp13. Now create another worker of type lb to balance the load between geronimo_ajp13 and geronimo_inst2_ajp13...
