Sequoia database clustering middleware with GlassFish and Java DB (Apache Derby)

Jagadish Ramu has written a demo and tutorial article to show how GlassFish and Sequoia can be used together to provide database clustering capability with Apache Derby / Java DB.

Sequoia is an open source database clustering middleware that allows any Java application to transparently
access a cluster of databases through JDBC. No code change is required to enable an application to have failover, replication capabilities.

This demo will have the modified sample application from Netbeans, deployed in GlassFish,
interacting with Sequoia controller for database operations with Apache Derby. The only change needed in the sample is to
configure the properties of jdbc-connection-pool to interact with the Sequoia controller.

Sun’s Open Source Contribution: $2 Billion, Dozens of Projects and Yes that includes Apache Derby

A nice spotlight on Open Source and Sun's contribution. Dan Roberts, Director of Marketing at Sun, chats with Simon Phipps, Sun’s chief open source officer.

"Did you know that Sun contributes more than $200 million per year of intellectual property to the open source movement, in dozens of open source projects? The company’s historical contribution tops $2 billion."

You can also find more about Sun's Free and Open Source initiatives at http://www.sun.com/software/opensource/

Java DB (Sun's supported distribution of Apache Derby) is one of the projects I'm proud to work on.

Connecting a GUI to a Java DB Database with NetBeans IDE


This NetBeans tutorial contributed by Talley Mulligan guides you through the process of connecting the GUI of an application to a Java DB database. It shows how to add data-aware JDBC components to the GUI that will enable the program to interact with the database.

If you have not seen it already, there is also a "Working with the Java DB (Derby) Database in Netbeans 5.5" tutorial contributed by Brian Leonard.

Archived Apache Derby Mailing lists - A great resource for Derby Users and Developers

I have been using Nabble for quite some time now and I have to say that it provides a great way to search and browse archived mailing lists.

If you need to get some Derby questions answered, you might want to do a search on the Apache Derby Users mailing list or the developers one, if you want to know more about Derby internals.

Of course, there is additional resources on the Apache Derby website itself.
