Eclipse’s Business Intelligence and Reporting Tools (BIRT) project is an open-source project based on the popular Eclipse IDE. The BIRT project had its first major release in the summer of 2005 and has garnered over ten million downloads since its inception. The project was started by Actuate Corporation which uses BIRT as the basis for many of its commercial products. The BIRT project's site includes an introduction, tutorials, downloads, and examples of using BIRT.Since 1.6, there has been a lot of work: #@body()content#end, #[[literal content]]#, major namespacing changes, $newListSyntax[$i], and more. [ Read more... ] This should be useable as a drop in replacement for Tools 1.4 or Tools 2.0-beta4, with a few minor exceptions. The 2.x series of VelocityTools requires Velocity 1.6 and JDK 1.5+.

Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites. Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat. Solr uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it easy to use from virtually any programming language.

Lucene - Overview
Apache Lucene(TM) is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform.Welcome to Apache Jackrabbit
The Apache Jackrabbit™ content repository is a fully conforming implementation of the Content Repository for Java Technology API (JCR, specified in JSR 170 and 283 ). A content repository is a hierarchical content store with support for structured and unstructured content, full text search, versioning, transactions, observation, and more. Apache Jackrabbit 2.4.1 is patch release that contains fixes and improvements over Jackrabbit 2.4.0. See the downloads page for more details. April 3rd, 2012: Apache Jackrabbit Oak 0.1 released Jackrabbit Oak 0.1 is to be considered alpha-level software.
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures. A wide variety of companies and organizations use Hadoop for both research and production. Users are encouraged to add themselves to the Hadoop PoweredBy wiki page. Described by the judging panel as a "Swiss army knife of the 21st century", Apache Hadoop picked up the innovator of the year award for having the potential to change the face of media innovations.

Commons Logging - Overview
The Logging Component When writing a library it is very useful to log information. However there are many logging implementations out there, and a library cannot impose the use of a particular one on the overall application that the library is a part of. The Logging package is an ultra-thin bridge between different logging implementations.
End of life The Commons HttpClient project is now end of life, and is no longer being developed. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules, which offer better performance and more flexibility. Introduction The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant protocol used on the Internet today.

Commons Collections The Java Collections Framework was a major addition in JDK 1.2. It added many powerful data structures that accelerate development of most significant Java applications. Since that time it has become the recognised standard for collection handling in Java. Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities.

Commons Chain - Overview
Commons Chain A popular technique for organizing the execution of complex processing flows is the "Chain of Responsibility" pattern, as described (among many other places) in the classic "Gang of Four" design patterns book. Although the fundamental API contracts required to implement this design patten are extremely simple, it is useful to have a base API that facilitates using the pattern, and (more importantly) encouraging composition of command implementations from multiple diverse sources. Towards that end, the Chain API models a computation as a series of "commands" that can be combined into a "chain". The API for a command consists of a single method ( execute() ), which is passed a "context" parameter containing the dynamic state of the computation, and whose return value is a boolean that determines whether or not processing for the current chain has been completed (true), or whether processing should be delegated to the next command in the chain (false).Commons CLI The Apache Commons CLI library provides an API for parsing command line options passed to programs. It's also able to print help messages detailing the options available for a command line tool. usage: ls -A,--almost-all do not list implied . and .. -a,--all do not hide entries starting with . -B,--ignore-backups do not list implied entried ending with ~ -b,--escape print octal escapes for nongraphic characters --block-size use SIZE-byte blocks -c with -lt: sort by, and show, ctime (time of last modification of file status information) with -l:show ctime and sort by name otherwise: sort by ctime -C list entries by columns
