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.

Janino is a super-small, super-fast Java™ compiler. Not only can it compile a set of source files to a set of class files like the JAVAC tool, but also can it compile a Java™ expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. Janino is not intended to be a development tool, but an embedded compiler for run-time compilation purposes, e.g. expression evaluators or "server pages" engines like JSP. JANINO is integrated with Apache Commons JCI ("Java Compiler Interface") and JBoss Rules / Drools. JANINO can also be used for static code analysis or code manipulation. JANINO can be configured to use the javax.tools.JavaCompiler API (available since JDK 1.6), which removes the Java 5-related limitations.

The JDT project provides the tool plug-ins that implement a Java IDE supporting the development of any Java application, including Eclipse plug-ins. It adds a Java project nature and Java perspective to the Eclipse Workbench as well as a number of views, editors, wizards, builders, and code merging and refactoring tools. The JDT project allows Eclipse to be a development environment for itself.

See Features for a summary of Bndtools features. Bndtools is based on Bnd, the powerful bundle tool created by Peter Kriens. Please read Why Bndtools? to learn why Bndtools has been created and why you should use it for OSGi development in Eclipse.

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.

" Jump to: navigation, search Welcome to our Wiki. This is the Wiki home page for the Buckminster Component Assembly project, an Eclipse Tools sub project. Buckminster is a component resolution & materialization framework. Its purpose is to get software components for you and materialize them in a context of choice, typically a workspace or file system. This applies whether you are looking at what's available on your local machine, within your development organization or in the public open source cloud. Buckminster reuses existing investments in a wide range of build and source management tools - Maven, ANT, CVS, SVN, PDE, etc. It removes ambiguity from component descriptions, enables component sharing and increases productiveness when applied in development, build, assembly and deploy scenarios.

Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications Spring Security is one of the most mature and widely used Spring projects. Founded in 2003 and actively maintained by SpringSource since, today it is used to secure numerous demanding environments including government agencies, military applications and central banks. It is released under an Apache 2.0 license so you can confidently use it in your projects. Spring Security is also easy to learn, deploy and manage. Our dedicated security namespace provides directives for most common operations, allowing complete application security in just a few lines of XML. We also offer complete tooling integration in SpringSource Tool Suite, plus our Spring Roo rapid application development framework. The Spring Community Forum and SpringSource offer a variety of free and paid support services. Spring Security is also integrated with many other Spring technologies, including Spring Web Flow, Spring Web Services, SpringSource Enterprise, SpringSource Application Management Suite and SpringSource tc Server.

The Simple Logging Facade for Java or (SLF4J) serves as a simple facade or abstraction for various logging frameworks, e.g. java.util.logging, log4j and logback, allowing the end user to plug in the desired logging framework at deployment time. Before you start using SLF4J, we highly recommend that you read the two-page SLF4J user manual. In case you wish to migrate your Java source files to SLF4J, consider our migrator tool which can migrate your project into SLF4J in minutes. In case an externally-maintained component you depend on uses a logging API other than SLF4J, such as commons logging, log4j or j.u.l, have a look at SLF4J's binary-support for legacy APIs.
