Manage Apache Pluto within Geronimo
Portal and portlet technology development is a hot skill to have, especially when developing Web 2.0-enabled applications. The Apache Pluto project is the reference implementation of the Java Portlet Specification, which was originally created through the Java Community Process and Java Specification Request (JSR) 168. The specification defines guidelines for portals and portlet components developed with the Java programming language. This specification is being recognized as the universal standard for traditional portals and as a framework for building pluggable Web applications. Find out how combining the Pluto project with Apache Geronimo's Java Platform, Enterprise Edition (Java EE) platform creates a highly flexible and powerful environment for building customizable and manageable systems using portals and portlets.

Transform Java classes into Web services using Axis2 and JiBX, Part 2: Turn your XML into a fully functional Web service
XML is powerful in that it can be used to define just about anything. What's more, it is the basis for an externally readable format for a majority of applications, most notably for the purposes of this series, Axis2 and JiBX. On top of that, as Web services become more and more ubiquitous, turning your legacy Java(TM) projects into full-fledged Web services is increasingly becoming a priority. Unlike in the past when the automatic generation of Web services was limited to a service and a single class, developers now have the option to generate a service or multiple services from the various Java classes in their existing projects. This article, the second part in a series of 2, uses Axis2 and JiBX to go from XML to a fully functional Web service from existing Java classes. 		Articles 22 Mar 2007

Little-G: Downsize your application server
How many times have you built simple applications and had to use heavyweight application servers to deploy them? Do you know what percentage of the many Java Platform, Enterprise Edition (Java EE) features you commonly use? I'd venture to guess only about 10%. Case in point: Apache Geronimo is a stable, open source, Java 2 Platform, Enterprise Edition (J2EE) 1.4-certified application server; but it's also feature rich, fat, and bulky. In an effort to build a simple, lightweight, but useful container for Web applications, the folks at Apache created Apache Geronimo Little-G, a stripped-down version of the original Geronimo application server. Though Little-G is not a J2EE-certified application server, it has most of the commonly used J2EE-compliant features, including a full Web container, a transaction manager, and database connectivity. In this article, you'll discover the features of Little-G and learn how to deploy and run Web applications on it. 		Articles 06 Mar 2007

The Geronimo renegade: Ease data access and configuration issues with the Spring Framework
If you're a typical developer, you'd no doubt welcome a solution to data access issues and embrace any tool that would make configuration easier. It's hard to have a conversation about Web applications in general, and these issues specifically, without somebody somewhere mentioning Spring. But good grief, do we really need another Web application framework? When I decided to do a Geronimo renegade piece on the intersection between Apache Geronimo and Spring, I knew it was high time to find out what all the Spring Framework buzz was about. I did that by cornering Jeff Genender. 		Articles 27 Feb 2007

The Geronimo renegade: Facing JSF
The last time I wrote a "Geronimo renegade" column, I was wondering what the big deal was about Spring, and when I followed up, I joked that now I needed someone to tell me why JavaServer Faces (JSF) was so hot. Wouldn't you know it that the next thing that crossed my desk was a request to do a piece on the intersection between Apache Geronimo and Apache MyFaces, focusing on their implementation of JSF? Well, it turns out to have been a good thing. I struck up a conversation with Tim McConnell at IBM, who's in the process of integrating Geronimo and MyFaces, and I learned a lot more than I expected about how specifications like this actually get implemented.

Two ways to build Apache Derby database applications in JRuby
JRuby is an implementation of the Ruby programming language that runs in the Java Virtual Machine (JVM). This tutorial demonstrates how to install and configure JRuby to connect to the Apache Derby database. As Ruby and Ruby on Rails become more popular, JRuby becomes an interesting technology to leverage the portability, security, and class libraries of the JVM while using Ruby features like simple syntax and closures. If you're writing a small application that needs a relational database, or you want to be able to ship a database with your product, then the Derby database is an excellent choice for a persistence mechanism. This tutorial shows you two methods of connecting to and building Derby database applications from JRuby. 		Tutorials 30 Jan 2007

Apache Geronimo and the Spring Framework, Part 1: Development methodology
Apache Geronimo is making news with its latest release, version 1.1. At its core is the Inversion Of Control (IoC) model, which is also the core pattern for the Spring Framework, a layered Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE) application framework developed under the Apache License. The Spring Framework was built on the principle that Java EE should be easier to use. This six-part tutorial series covers the complete Spring Framework, front to back, including how to implement its functionality with Apache Geronimo. This installment, Part 1 of the series, introduces you to the Spring Framework architecture and explores the intersection between Geronimo and Spring. 		Tutorials 12 Sep 2006

The Geronimo renegade: OSCON 2006: An open invitation
As might be expected, open was the buzzword, theme, and overarching feeling at OSCON 2006, the O'Reilly Media Open Source Conference. The renegade got to witness and join in on many discussions on the topic of open source vs. open community, the importance of an open community, and its impact on an open source project. Participants also discussed the notion that not getting paid to work on open source projects might just be a good thing -- but how does this affect corporate interests that contribute time, money, and employees to open source projects? And when it's said that Apache Geronimo and Apache Derby are open source projects with open communities, just what does that mean anyway?

Remotely deploy Web applications on Apache Geronimo
Apache Geronimo is a Java 2 Platform Enterprise Edition (J2EE) 1.4-certified application server. When most people think of J2EE, they think of things like transaction management, Web applications, and asynchronous messaging. Those features, however, aren't necessarily a guarantee for J2EE certification. An application server must provide many tools needed for mission-critical production systems. One of those tools is remote deployment. Geronimo is designed to meet the most demanding development situations, so it includes excellent support for remote deployment. This article explains the many ways to remotely deploy an application using Geronimo. Learn how to remotely deploy an application using a command-line tool (the Geronimo deployment tool) and a browser-based tool (the Geronimo Administration Console), and how to deploy an application within an integrated development environment (Eclipse). This article also provides a simple example of remote deployment using a small Web application. 		Articles 02 May 2006
