Lutris R&D Partners Makes It
to Next Level
By Christophe Ney,
Lutris Technologies, France
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.
