Lutris R&D Partners Makes It to Next Level

Last Thursday, at Linux Expo Paris, ObjectWeb co-founders announced the birth of a consortium in a press conference. As a Lutris representative I was there with top managers from BULL, France Telecom R&D and INRIA, the major players of ObjectWeb consortium. INRIA already hosted W3C the Internet standardization organization, with Objectweb it now aims at providing open-source middleware infrastructure. Lutris Technologies has been involved since the beginning in this federation of European and International open source initiatives, Lutris CTO, Paul Morgan being in the ObjectWeb board and myself a member of the college of architects.

The story begins in 1999 when Lutris looking for EJB technology providers, joins BULL and France Telecom partnership to build its J2EE platform. Since then, a lot has been achieved; several components have been industrialized and have become essential parts of LEAS and other platforms. The initiative has attracted other industrials like Schlumberger, other standardization players of OMG or AFNOR, as well as a cloud of startup businesses.

During those years, Lutris has constantly contributed to the creation of components, providing leading technology from Enhydra server and contributing to a redesign of existing ObjectWeb plateforms. Under the Enhydra.org umbrella, Lutris has also launched number of complementary open-source projects that have been adopted by Objectweb partners.

Today (4 Feb 2002), we deliver Lutris EAS 4.1 with an EJB container and a transaction manager based on ObjectWeb technology. These components have already been deployed and have proven their reliability in the open source world. The EJB container initially coming from the JOnAS plateform has been isolated to allow hot deployment of enterprise java bean modules from within J2EE application archives. A new propagation context mechanism with intraVM call optimizations has been plugged to improve RMI/JRMP performances. JAAS like security has been added allowing nested EJB calls to run with new credentials. The configuration and instrumentation of the container has been made available to the Lutris Management Console (LMC) via JMX MBeans.

The work performed for other components depends on their nature: It ranges from straightforward isolation of the code and unit tests for the Transaction Manager, to major redesign with the inclusion of best of the breed technologies coming from Enhydra for the Database manager.

In upcoming versions of Lutris EAS , we will embed RMI/IIOP ORB, Message-Oriented Middleware, JCA implementation and Persistence Engine coming from the same ObjectWeb partners. We strongly believe that the creation of the consortium will attract new partners and will give birth to new open source projects, making more and more components available to us and eventually to Lutris EAS users.
