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 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::ePerl is a fast emulated Embedded Perl (ePerl) facility.

SYNOPSIS

# Apaches httpd.conf file
# mandatory: activation of Apache::ePerl
PerlModule Apache::ePerl
< Files ~ "/root/of/webmaster/area/.+.iphtml$" >
Options +ExecCGI
SetHandler perl-script
PerlHandler Apache::ePerl
< /Files >
# optional: configuration of Apache::ePerl
< Perl >
$Apache::ePerl::Config->{BeginDelimiter} = $Apache::ePerl::Config->{EndDelimiter} = !>;
$Apache::ePerl::Config->{CaseDelimiters} = 0;
$Apache::ePerl::Config->{ConvertEntities} = 1;
< /Perl >
# optional: activation of Apache::Status for Apache::ePerl
< Location /perl-status >
Options +ExecCGI
SetHandler perl-script
PerlHandler Apache::Status
< /Location >

This packages provides a handler function for Apache/mod_perl which can be used to emulate the stand-alone Server-Side-Scripting-Language ePerl (see eperl(3) for more details) in a very fast way. This is not a real 100% replacement for nph-eperl because of reduced functionality under some special cases, principal runtime restrictions and speedup decisions. For instance this variant does not (and cannot) provide the SetUID feature of ePerl nor does it check for allowed filename extensions (speedup!), etc. Instead it uses further features like object caching which ePerl does not use.

But the accepted bristled source file format is exactly the same as with the regular ePerl facility, because Apache::ePerl uses the Parse::ePerl package which provides the original ePerl parser and translator. So, any valid ePerl which works under nph-eperl can also be used under Apache::ePerl.

The intent is to use this special variant of ePerl for scripts which are directly under control of the webmaster. In this situation no real security problems exists for him, because all risk is at his own hands. For the average user you should not use Apache::ePerl. Instead additionally install the regular stand-alone ePerl facility (nph-eperl) for those users.

So, the advantage of Apache::ePerl against the regular nph-eperl is better performance and nothing else. Actually scripts executed under Apache::ePerl are at least twice as fast as under nph-eperl. The reason its not that ePerl itself is faster. The reason is the runtime in-core environment of Apache/mod_perl which does not have any forking overhead.

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-top provides real-time display of the active processes from a remote apache server.
With apache-top you can get:
- The active apache processes with their associated PID, the status, the seconds being active, the CPU usage, the asociated VirtualHost, the accessing ip and the request (POST or GET, the file being accessed and the used protocol)
- The server uptime and the last time it was restarted
- The CPU usage
- Requests by second, Kb by second and the average Kb by request
- Number of active and inactive processes
- A graph with the inactive and active processes and their status

The Apache::FileManager module is a simple HTML file manager. It provides file manipulations such as cut, copy, paste, delete, rename, extract archive, create directory, create file, edit file, and upload files.
It also has the ability to rsync the server htdocs tree to another server with the click of a button.
Enhancements:
- prevented file edit screen from opening when cancel is clicked when creating new filenames
- fixed up documentation
