"Build a better mousetrap, and the world will
beat a path to your door."
--Emerson

Our Mission? To provide a complete, Java-based solution for accessing, manipulating, and outputting XML data from Java code. Read more about our project goals.
Project Status? JDOM 2.0.5 is available! This is a recommended upgrade for anyone still using JDOM 1.1.3 or earlier, and using Java5 or later. JDOM 2.0.5 contains a few fixes:
  • Fixes Issue 106 - Uses different methods on StAX Stream output to ensure that Namespace URI's are prefixed correctly.
  • Fixes Issue 111 - Improve documentation for SAXBuilder.build(String) so that it is more obvious that the String is not actual XML values, but a URI.
  • Fixes Issue 112 - Improves performance of SAXBuilder when there are large ( greater than 1KB ) text sections in the input XML.
  • Fixes Issue 113 - Compile (and test) against Jaxen 1.1.6
  • Fixes Issue 114 - Setting the Line Separator for JDOM would not work from System.properties().
  • Fixes Issue 115 - Correctly set the 'xmlns' prefix and URI for Namespace declarations in DOMOutputter.
  • Fixes Issue 116 - JDOM 1.x uses an iterator to output XML child content, modify JDOM 2.x to do the same.

JDOM 2.x versions are a significant reworking of the JDOM API to enhance it with Generics, and other Java Language features introduced with Java 5. JDOM 2.x is fully supported for use with Java 6 or Java 7, and is also compatible with Java 5 with a few restrictions. See the full Statement on Supported Versions and Dependencies

To facilitate the deployment of JDOM 2.x, the entire JDOM package has been renamed. If you are migrating to JDOM 2.x from previous JDOM versions you will need to change your package imports from org.jdom.* to org.jdom2.*

A full JDOM 1.x to JDOM 2.x migration guide is available.

JDOM 1.x versions are operating in maintenance mode only and only bug fixes will be considered for future 1.x releases. The only reason to continue using JDOM 1.x is for compatibility with older Java versions (back to Java 1.2).

New features are being considered for JDOM2 though. If you want to be involved, or have suggestions or questions, please write in to the mailing list and check out the GitHub Repository.

The Latest?

Mission accomplished. We've succeeded in our mission with an API that's been through years of design and development and a codebase that is rock solid.

What about JSR-102? That's a good question. It hasn't been a priority for us. We seem to be doing pretty well on our own, it turns out.

If you are wondering what Jason has been doing lately, he's working on MarkMail. It's a searchable email archive system. You can try searching the JDOM lists at jdom.markmail.org.

What's Next?

JDOM 2.0.x versions are out, and work is starting on identifying what new features can be added to a future 2.1.x release series. If you have comments, questions, or suggestions for something that is, or should be, in a 2.1.x release, please write in to jdom-interest. Current features being considered are improved XPath support (XPath 2.0) and updated XSLT processing, and also an extended StAX Handling API.
