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.

Securing the embedded Derby database

By default, the embedded Derby database server does not use authentication for database connections. Security for the Derby database can be enabled by creating a derby.properties file under the <GERONIMO_HOME>/var/derby directory. The contents of a sample properties file are shown below: 

derby.connection.requireAuthentication=true
derby.authentication.provider=BUILTIN
derby.user.userName1=password1
derby.user.userName2=password2

Here, the authentication mechanism used is BUILTIN, whereby the usernames and passwords are specified in the properties file itself. The authentication methods that can be used are:

  • BUILTIN—User credentials are specified in the derby.properties file

  • LDAP— Configure an LDAP server for authentication

  • User defined Class should implement org.apache.derby.authentication.UserAuthenticator

In derby.properties, two users— "userName1" with password "password1" and "userName2" with password "password2" are created.

Users can...
