Apache Harmony is the Java SE project of the Apache Software Foundation. Please help us make this a world class, certified implementation of the Java Platform Standard Edition!

Apache Harmonys aim is to produce a large and healthy community of those interested in runtime platforms tasked with creation of :

A compatible, independent implementation of the Java SE 5 JDK under the Apache License v2.
A community-developed modular runtime (VM and class library) architecture.

We aim to support wide range of different platforms. The main criteria for whether a particular platform is supported or not is the involvement of people in running tests on regular base, reporting build status, finding and fixing bugs for that platform, and so on. We have a list of platforms we are actively maintaining at the moment.

Project Status

JRE and HDK snapshots available
JRE can run popular programs like Apache Tomcat, Eclipse, Maven, Derby, Ant
More than 95% of Java 5 API complete. (not compatible, just completed)
More than 1.25 Million Lines of Code

Apache Incubator project is the entry path into The Apache Software Foundation (ASF) for projects and codebases wishing to become part of the Foundations efforts.

All code donations from external organisations and existing external projects wishing to join Apache enter through the Incubator.

The Apache Incubator has two primary goals:

- Ensure all donations are in accordance with the ASF legal standards
- Develop new communities that adhere to our guiding principles

Apache Ant is a Java based build tool, similar to make, but with better support for the cross platform issues involved with developing Java applications.
Apache Ant is the build tool of choice for all Java projects at Apache and many other Open Source Java projects.
Enhancements:
- A resource framework was introduced.
- Some of the core ant tasks such as copy are now able to process not only file system resources but also zip entries, tar entries, and paths.
- Resource collections group resources, and can be further combined with operators such as union and intersection.
- This version starts outsourcing of optional tasks to Antlibs.
- The .NET antlib replaces the .NET optional tasks.
- Support for the version control system Subversion is also provided as an antlib.
- A large number of bugs were fixed.
- Some initial support for Java6 features was added.

AntUnit is a library of Ant tasks that was initially developed to write tests for Ant tasks without resorting to JUnit. Apache AntUnit makes it easy to turn an existing build file that exhibits an error into an AntUnit test.

Tests are written as targets in a build file using assertion tasks provided by AntUnit. The antunit task executes targets in a collection of build files and supports custom listeners in a manner similar to the junit tasks formatters.

Apache Solr is a high performace search server based on Lucene, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a Web administration interface.
The project is currently under incubation at the Apache Software Foundation.
Instructions for Building Apache Solr
1. Download the J2SE 5.0 JDK (Java Development Kit) or later from http://java.sun.com. You will need the JDK installed, and the %JAVA_HOME%bin directory included on your command path. To test this, issue a "java -version" command from your shell and verify that the Java version is 5.0 or later.
2. Download the Apache Ant binary distribution from http://ant.apache.org. You will need Ant installed and the %ANT_HOME%bin directory included on your command path. To test this, issue a "ant -version" command from your shell and verify that Ant is available.
3. Download the Apache Solr source distribution, linked from the above incubator web site. Expand the distribution to a folder of your choice, e.g. c:solr.
4. Navigate to that folder and issue an "ant" command to see the available options for building, testing, and packaging solr.
Enhancements:
- This is the first release since graduating from the Apache Incubator.
- Some of the new features include CSV/delimited-text data loading, time based autocommit, faster faceting, negative filters, a spell-check handler, sounds-like word filters, regex text filters, and more flexible plugins.

Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java.
Apache Lucene is a technology suitable for nearly any application that requires full-text search, especially cross-platform.
Enhancements:
- Many new features, optimizations, and bugfixes have been added since 2.1.0, including "point-in-time" searching over NFS, payloads, function queries, and new APIs for pre-analyzed fields.
- This release includes index format changes that are not readable by older versions.
- It can both read and update older Lucene indexes.
- Adding to an index with an older format will cause it to be converted to the newer format.

Apache VelocityTools project is a collection of Velocity subprojects with a common goal of creating tools and infrastructure for building both web and non-web applications using the Velocity template engine.
Enhancements:
- A key focus in this version has been ease of use.
- It simplifies developing your own tools (by removing the ViewTool and Configurable interfaces), as well as the syntax for using existing tools within Velocity templates.
- Theres also a new showcase Web app that demos many uses of the various tools and lets you interactively play with them.
- Download the binary distro and deploy the showcase.war to your servlet container.
- Also included is the usual slate of bugfixes, dependency upgrades, entirely new tools, and new functions for existing tools.

Apache Portable Runtime (APR) project mission is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations.
The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
Main features:
- Atomic operations
- Dynamic Shared Object loading
- File I/O
- Locks (mutexes, condition variables, etc)
- Memory management (high performance allocators)
- Memory-mapped files
- Multicast Sockets
- Network I/O
- Shared memory
- Thread and Process management
- Various data structures (tables, hashes, priority queues, etc)
Enhancements:
- Various bugs were fixed.
- The API compatible with version 1.2.7.
