Welcome to The Jakarta Project
|
The Jakarta Project creates and maintains open source solutions on the
Java platform for distribution to the public at no charge.
Jakarta products are
developed by and distributed through various subprojects, which are listed under
Products in the menu on the left, some other Apache Java projects which may be of interest are listed in Related,
and all are summarised in the section below.
Each Jakarta subproject has its own team of developers and committers, and its
own mailing list.
Related projects have their own project management, developers, committers, their own websites and mailing lists.
All Jakarta product support is provided through the subproject
mailing lists.
All work at Jakarta is provided on a volunteer
basis. There is no paid staff. Please be considerate and do your homework
before asking our volunteers to donate additional time and energy to your project.
Jakarta is a project of The Apache Software Foundation(ASF), and like all Apache Projects, encourages a collaborative, consensus-based
development process, offers an open and pragmatic
software license, and strives to
create software of the highest quality.
The ASF is organized into several projects,
which like Jakarta, may contain various subprojects.
For more about these projects and their subprojects, visit the
ASF Project page.
