Xcalia™ Contributes Jalisto as Open Source to ObjectWeb

Provides Lightweight Database Solution for Transactional Java Applications

PARIS -- (MARKET WIRE) -- September 6, 2005 -- Xcalia, a leading provider of business integration software, today announced that it has made its lightweight Java database, Xcalia Jalisto™, available as Open Source. Jalisto is transactional, has a very small footprint and provides high performance. It is 100% pure Java and object-oriented. The project will be hosted by ObjectWeb (, an established and respected open source community with a focus on the development of industry-grade distributed middleware.

Jalisto comes in two versions: Jalisto SE (Standard Edition) and Jalisto ME (Micro Edition). Jalisto SE is an ideal solution for embedded and standalone systems. Jalisto ME, which will be available in Q4, targets mobile environments including cell phones, PDAs, and is compatible with the Java 2 Platform Micro Edition (J2ME).

As Carl Olofson, research director at IDC, reported recently: "Object-oriented DBMSs could well enjoy a second growth period as embedded DBMSs due to the efficient and flexible data management they offer object-oriented applications, and open source DBMSs are also attractive as embedded DBMSs because of the technological control they offer ISVs as well as flexibility in licensing."

"As a member of ObjectWeb since 2001, and an active participant in the open standards community, we share the same goal for improving solutions for large enterprise customers," said Eric Samson, Chief Technology Officer for Xcalia. "Jalisto has helped Xcalia's customers build enterprise solutions faster, and we are pleased to make it available for further open source development. In addition, we recently selected Jonas application server and JORAM message-oriented-middleware as packaged components of our new platform for data and service intermediation and have additional plans to expand our joint offerings for unified open source solutions."

"Embedded and mobile computing is definitely a hot topic today. In this context, developers and users need lightweight solutions for persistence," said Christophe Ney, ObjectWeb's executive director. "We expect Jalisto to bring the benefits of transactional storage without having to use traditional heavyweight commercial SQL client/server databases. It nicely complements our roster of open-source components for persistence that includes, for instance, JORM, an adaptable persistence service for Java Object Repository Mapping and MEDOR, a Middleware Enabling Distributed Object Requests."

Jalisto SE offers developers a flexible object database for lightweight applications and is well suited for embedded environments. Key functionality includes an optional Java query engine, caches, high performance and an interchangeable disk access layer and local storage for complex object structures. It replaces the need for serialization and can be used to replicate part of the data from central systems to a local standalone client. Jalisto SE features easy JMX (Java Management Extension) administration and support for record-level pessimistic and optimistic locking. It can be deployed for single or multi-users in standalone for optimal performance and a client/server mode is also available. It is compliant with Java Connector Architecture (JCA) to ease the integration with Application Servers.
