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 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 XML Projects goals are:
- to provide commercial-quality standards-based XML solutions that are developed in an open and cooperative fashion,
- to provide feedback to standards bodies (such as IETF and W3C) from an implementation perspective, and
- to be a focus for XML-related activities within Apache projects
The Apache XML Project used to be the home for many XML-related subprojects, many of which have moved to top-level project status recently or are currently in migration. The Apache XML Project slowly transforms into an place where you can find pointers to XML-related projects here in the Apache Software Foundation. The remaining subprojects directly under the supervision of the XML PMC are:
- AxKit - XML-based web publishing, in mod_perl
- Crimson - A Java XML parser derived from the Sun Project X Parser.
- Xang - Rapid development of dynamic server pages, in JavaScript
- Xindice - A native XML database.
- XML Commons - focussed on common code and guidelines for XML projects
- XML Security - Java and C++ implementations of the XML signature and encryption standards

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.
