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".

The old CVS repository is no more available.

For more information, see JOTM CVS page (and Download page for a list of available modules).

5th December 2002: JOTM needs a logo!

A logo is a fundamental part of an Open Source project (what would be Linux without its penguin! ;-). So JOTM needs a logo to improve its visibility inside and outside ObjectWeb community.

We have started to design some logos but they are not very imaginative or original... :-(

If you've some logos designer talent, do not hesitate to modify ours (or better, create new ones) and send it to me (in a vectorial format).

Have fun!

5th December 2002: First release of JOTM-BTP (CVS module: jotm-btp)

JOTM-BTP is an extension to JOTM which provides an Open Source implementation of BTP (Business Transaction Protocol) which provides transactions for Web Services.
It was contributed by Pierre-Yves Gibello and Xavier Spengler of Experlog. Thanks guys!

• JOTM-BTP is available on CVS (as jotm-btp module) or a package can be downloaded from JOTM SourceForge page
• Guide and Javadoc are available on the documentation page.
• A demonstration is provided with JOTM-BTP. It is based on a Travel Agency which books hotels and flights within the same transaction. It uses also Tomcat and Axis and 3 Web Services (see JOTM-BTP guide for more information).

This first extension to JOTM is a very important landmark because it is the very first step to fulfill our vision of JOTM to provide several transaction models.

Do not hesite to try it, test it and give us your feedbacks. Enjoy!

2nd December 2002: JOTM at ObjectWeb Conference

The 2nd ObjectWeb conference was held near Paris, France, on 28-29th November. It was the occasion to present several works around JOTM and to meet people who were interested by JOTM.

• Philippe Merle did a presentation on "Projects and development activities overview", taking JOTM as an example for the architecture vision for ObjectWeb (his presentation is not online yet)
• Marek presented JOTM status (JOTM: where are we going?)
• Pierre-Yves Gibello presented work done around JOTM and BTP (JOTM and the Business Transaction Protocol). Pierre-Yves also did a tutorial about BTP and Web Services based on his implementation.
• Romain Rouvoy showed his work on Abstraction of transaction demarcation in component oriented middleware which he applied to JOnAS (as the application server) and JOTM (as the TM). However his work is generic and can be applied to any app server and TM.

Thank you all for your presentations.

JOTM team would also like to thank people who came to this conference and were interested by JOTM. We do believe that JOTM can gather an important community around middleware transactions (JTS, OTS, BTP, ONT, CNT,...) and we're looking forward to future discussions and works about it.
