JORAM: Java (TM) Open Reliable Asynchronous Messaging

JORAM Logo

JORAM has been made available for download since May 2000.
As a standalone software, JORAM has been downloaded more than 100,000 times.

Introduction

JORAM incorporates a 100% pure Java implementation of JMS 1.1 (Java Message Service API released by Sun Microsystem, Inc.) specification.
It provides access to a really distributed MOM (Message Oriented Middleware), built on top of the ScalAgent D.T. agents based platform.

JORAM is a mature project started in 1999, it is an open source software released under the LGPL license since May 2000.
It provides a production ready distributed MOM already used within many critical operational applications.

Joram is now designed with an OSGiTM based services architecture to provide a dynamically adaptable messaging server:

  • The Joram server can be launched as a set of OSGi bundles (it is always possible to launch the server as a classic Java program).
  • Additional services can be started, stopped, reconfigured: Command line interface, Web console, etc.

Stable versions of JORAM are JMS 1.1 and 2.0 compliant. Moreover JORAM is used by JOnAS to undergo the Java EE certification, and has passed all tests concerning JMS certification in this J2EE TCK.
Professional Support and training are available from Scalagent D.T..

September 18, 2014: CNES workshop - Mobility for operations

CNES (the french space agency) has organized a workshop on 18th September about mobility for operations. The question is to allow remote users to use the services of an operations center from Internet. This could be for controlling a satellite, or for managing scientific on-board instruments. The topic covers also cooperative missions which involve several agencies and other entities.

David Féliot will be there for ScalAgent D.T. to present the interest of the MQTT technology in this context, and the value of the MQTT implementation in JoramMQ Entreprise.

September, 2014: MQTT implementation on top of Joram.

ScalAgent D.T. has implemented the version 3.1 of the MQTT protocol integrated with JoramMQ Entreprise. An intensive performance evaluation campain demonstrates the stability and scalability of the middleware, under stress conditions including a very high throuput of messages and an extremely large number of clients.

Find all détails of this study in the white paper to download: JoramMQ_MQTT_white_paper

December 2nd and 3rd, 2009: JORAM Training Session, Grenoble, France

A two-day training session about JORAM is scheduled in Grenoble; it will be delivered in french language.

The session is entitled "Design and Deploy a Distributed JORAM Messaging System".

This training session is targeted at architects and system designers that intend to integrate the JORAM component within a global distributed solution. It includes a significant part of experimentations and case studies based on real-world application scenarios.

The session is conducted by ScalAgent Distributed Technologies, the leading developer of the JORAM component. We offer to share our expertise through a training session aiming at providing the key knowledge to use and deploy a JORAM system that fits your own requirements. This two-day session details the design principles of JORAM and describes the best practices that will enable to take advantage of its advanced properties for complex networked environments.

Detailed information about this training session is available online (PDF, in french only)
