2007 entscheidet sich Oracle, die Quellcodes seines erfolgreichen Persistenz-Projektes TopLink an die Eclipse Foundation zu übergeben. Seither wird das Projekt unter dem Namen EclipseLink weiterentwickelt und wurde jüngst als Referenzimplementierung für die Java Persistence API 2.0 ausgewählt. EclipseLink-Lead Doug Clarke spricht im Interview mit dem Eclipse Magazin über die Hintergründe der Migration zur Eclipse Foundation und über die Vorzüge von EclipseLink gegenüber anderen Persistenz-Frameworks wie Hibernate.

While there are a number of references for Maven online, there is no single, well-written book that can serve as both a well-worn reference and an introduction. What we've tried to do with this effort is provide both a comprehensive reference and a narrative introduction to Maven. Published by O'Reilly, Maven: The Definitive Guide is written for both new and season Maven users.

SmartSprites will let you easily introduce and maintain CSS sprites in your designs. SmartSprites parses special directives you can insert into your original CSS to mark individual images to be turned into sprites. It then builds sprite images from the collected images and automatically inserts the required CSS properties into your style sheet, so that the sprites are used instead of the individual images. SmartSprites parses special directives you can insert into your original CSS to mark individual images to be turned into sprites. It then builds sprite images from the collected images and automatically inserts the required CSS properties to your style sheet, so that the sprites are used instead of the individual images. In other words, no tedious copying & pasting to your CSS when adding, removing or changing sprited images. Just work with your CSS and original images as usual and have SmartSprites automatically transform them to the sprite-powered version when necessary.

Lucene is an Open Source, mature and high-performance Java search engine. It is highly flexible, and scalable from hundreds to millions of documents. Luke is a handy development and diagnostic tool, which accesses already existing Lucene indexes and allows you to display and modify their content in several ways: * browse by document number, or by term * view documents / copy to clipboard * retrieve a ranked list of most frequent terms * execute a search, and browse the results * analyze search results * selectively delete documents from the index * reconstruct the original document fields, edit them and re-insert to the index * optimize indexes * and much more... Recent versions of Luke are also extensible through plugins and scripting. I started this project because I needed a tool like this. I decided to distribute it under Open Source license to express my gratitude to the Lucene team for creating such a high-quality product. Lucene is one of the landmark proofs that Open Source paradigm can result in high-quality and free products.

Recently I decided to get up to speed on at least one rich client platform for a project we had. Over the years I had come across references to Eclipses RCP and Netbeans RCP so I started with those two.
