"The Maven Archiver is mainly used by plugins to handle packaging. The version numbers referenced in the Since column on this page are the version of the Maven Archiver component - not for any specific plugin. To see which version of Maven Archiver a plugin uses, go to the site for that plugin. "

migrate4j is a database migration tool. Suppose you determine that you need a new database table for your project. If you develop alone, you could write an SQL script that adds a table and manually apply this to your development system. But if you work with other developers, or need to keep a test system in synch with your development system, this become tedious and error prone. Migration tools make it possible to add your new table (or make any other schema changes) in an automated fashion, ensuring all your systems are always in synch. Migration tools also make it possible to quickly and easily roll back previous changes. Unlike typing commands into an interactive SQL window or storing SQL scripts, migration tools keep a detailed history of how your database schema evolved (just in case you need to go back to a previous version). Finally, migration tools minimize or eliminate the problem of having to use vendor specific syntax - you may never switch database products, but if you do, using a migration tool will make your life much easier. The initial intent of migrate4j was to make a Java version of Ruby's db:migrate. If you've used db:migrate, you probably fell in love with it's simple syntax, easy configuration and ability to roll changes up and back effortlessly. The intent (and the challenge) of migrate4j is to bring the power and simplicity of db:migrate to Java programmers, using familiar type safety and syntax. Along the way, we're adding additional functionality that makes migrate4j more than just another Ruby tool rewritten for Java - it is a Java project intended to make other Java projects even better.

JDBC 4.0 Enhancements in Java SE 6 Java Platform, Standard Edition (Java SE) version 6 (code name Mustang), is currently in its second beta release and is scheduled to be delivered in October of this year. Java SE 6 includes several enhancements to the Java Database Connectivity (JDBC) API. These enhancements will be released as JDBC version 4.0. The main objectives of the new JDBC features are to provide a simpler design and better developer experience. This article provides an overview of the JDBC 4.0 enhancements and what benefits they offer to enterprise Java developers. We will explore the new JDBC features with the help of a sample loan processing application using Apache Derby as the back-end database.

Database Change Management You never develop code without version control, why do you develop your database without it? Liquibase is an open source (Apache 2.0 Licensed), database-independent library for tracking, managing and applying database changes. It is built on a simple premise: All database changes are stored in a human readable yet trackable form and checked into source control. Liquibase Supports: Extensibility Merging changes from multiple developers Code branches Multiple Databases Managing production data as well as various test datasets Cluster-safe database upgrades Automated updates or generation of SQL scripts that can be approved and applied by a DBA Update rollbacks Database "diff"s Generating starting change logs from existing database

Aspect-oriented computing is continuing to increase in popularity. The modularity inherent in OSGi and Eclipse offers unique opportunities for managing and applying aspects by supplying them in bundles and directing their application to particular sets of bundles. This incubator work area is dedicated to delivering an integration of aspects and OSGi. The goal is to allow developers to use the Equinox together with AspectJ by combining the benefits of both worlds. Using a load-time weaving extension you are able to add AspectJ aspects to your bundle-based system just by putting them into general OSGi bundles. It does not matter if the pointcuts you defined inside the aspects contain join points that are defined by classes within the same bundle or any other bundle in your installation. The load-time weaving extension will take care that your aspects are woven with the appropriate classes at load-time. To illustrate this lets assume the following situation: You would like to write an aspect that traces something within the JDT plug-ins of Eclipse. Without some kind of load-time aspect weaving you would somehow need to recompile those JDT plug-ins using AJDT (for example) together with your aspect. By using the load-time aspect weaving extension all you need is to implement your aspect and add that bundle to your system. The load-time aspect weaving extension takes care of weaving your aspect with the JDT code as it is loaded. And it doesn't matter if a new JDT is installed by the user later on. The next time your application is started the load-time aspect weaving will take care of weaving your aspect into these bundles as well, if necessary. With this technology is becomes possible to modularize crosscutting concerns across different plug-ins while keeping the idea of separate compilation for bundles. Goals Provide Runtime Modularity and Versioning for Crosscutting Concerns: Aspects are used to implement crosscutting concerns. However such concerns usually compr

The SpringSource Bundle Repository provides OSGi-ready versions of hundreds of open source enterprise libraries that are commonly used when developing Spring applications.

Spring hat sich mittlerweile für viele Projekte als Framework etabliert. Es stellt mit seiner umfangreichen Unterstützung für viele typische Herausforderungen eine universelle Hilfe bei der Java-Entwicklung dar. Die Version 3.0 wird einige interessante Erweiterungen bieten - dieser Artikel wirft einen ersten Blick auf die Neuerungen bis Meilenstein 1.

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.

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.

Eclipse Gemini Blueprint is the reference implementation for the OSGi Alliance Blueprint Service (chapter 121 of the OSGi 4.2 Compendium Specification). Gemini Blueprint project makes it easy to build Java applications that run in an OSGi framework. By using Gemini Blueprint, applications benefit from using a better separation of modules, the ability to dynamically add, remove, and update modules in a running system, the ability to deploy multiple versions of a module simultaneously (and have clients automatically bind to the appropriate one), and a dynamic service model. Gemini users may also be interested in Eclipse Virgo, an open source, completely modular, OSGi-based Java application server. Its documentation is considered a supplement to Gemini Blueprint as it explains in detail, how OSGi can be used in various development and production scenarios.
