15 February 2005: NOTICE

The JOTM Team has recently implemented XA Recovery in JOTM including the development of a high-speed journal package, which is very efficient in managing the persistence of transaction log records. See High Speed ObjectWeb Logger for more information about HOWL.

Both projects were a significant amount of work and we are quite excited about the possibilities that both projects bring to ObjectWeb. The version of JOTM supporting XA recovery is currently in place as of JOnAS 4.3.1, but unfortunately not yet published to our web site. To improve the useability and quality of the XA Recovery feature, we are working on improving the administrative interface to JOTM, updating the user documentation (including the web site) and beefing up our test suites.

We are also encouraging the Open Source Database community to implement XA Recovery in their DBMSs.

Open Source For Business (OFBiz) has released a new version 2.1.0 which integrates JOTM as its transaction manager.
Their release notes state that:
"Another major new change is the integration with the JOTM transaction manager which is a replacement for Tyrex. This means that a very simple configuration can now be deployed with only a servlet container and a stand-alone transaction manager, and without the difficulties that Tyrex brings with it".

Andy Zeneski, from OFBiz, also wrote the first JOTM Success Story. Thanks Andy and good work for OFBiz!

JOTM : A Java Open Transaction Manager

What We Have Accomplished

Today the JOTM team delivers to you a Java Open Source implementation of the JTA APIs. This implementation is fully functional and mature since it has been used for several years in the JOnAS application server project.

What's Next

Tomorrow we aim at delivering adaptable software that can be used in a wide range of use cases involving transaction management. In particular we are currently looking at covering transaction models such as flat, CNT, ONT, BTP and transaction standards including JTA, JTS, OTS.

How Do We Get There?

Our plans are to conduct in parallel the following actions:

Leverage The Existing Code Base

Current code base is available on the download page, developers can find the detail of the work in progress on the scheduled action page. We provide support on the jotm@objectweb.org mailing list. A bug tracker and a feature request tool are available on JOTM SourceForge page

Grow A Shared Expertise

We have just started a documentation page that we intend to use as a repository of background material for the project. We welcome contribution and expertise for this aspect of the project. You may find contact information on the JOTM team page.

Develop A More Generic Architecture

There is no publication yet. Preliminary discussion takes place on both project JOTM and ObjectWeb architecture mailing lists.
