JORAM: Java (TM) Open Reliable Asynchronous Messaging

		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 OSGi^TM 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 certified. Moreover JORAM is used by JOnAS to undergo the Java EE 5 certification, and has passed all tests concerning JMS 1.1 certification in this J2EE TCK.
Professional Support is available from Scalagent D.T..

July 13, 2011: JORAM/AMQP 1.0 is released

Joram team is proud to announce the final version of the implementation of the specification AMQP v0.9.1. This version successfully passed interoperability testing with RabbitMQ and QPID, it is available in Maven reprository.

July 13, 2011: JORAM 5.6.0 release is available.

This release introduces some improvements and bug fixes, essentially:

• Changes on JCA connector enabling Joram to be started as a JOnAS OSGi service.

  • Fix NPE in AMQP distribution destination when amqp.Routing property is not correctly set.
  • Fix possible NPE in JMS module for acquisition and distribution JMS bridge destinations.
• Fix a potential issue in PoolNetwork when a connection is initiated by a bad component (the incoming component still connected).
• Adds samples configurations for Derby and NGT Transaction components.
• Adds samples configurations and clients for HttpNetwork Network components.
• Updates performance sample.

This version is available for download, and in Maven repository.

It is tagged in SVN (JORAM_5_6_0), the complete list of changes can be viewed either in code updates or in SVN history.

November 24-25, 2010: OW2 Annual Conference, Paris, France.

During the OW2 Annual Conference, Serge Lacourte (ScalAgent D.T.) presents two very different Use Cases of Joram. They demonstrate the ability of Joram to adapt to very different deployment environments, thanks to the very high configuration capability of its architecture.

The slide show is available on the OW2 web site: Configuration from clustering to WAN distribution with Joram.

May 18, 2010: JORAM Architecture Designer plugin 1.0.0 is available

The first official release of Joram Architecture Designer plugin for Eclipse is available for download (package JORAM_DESIGNER at the end of the page). A brief PDF installation guide is available for download.

As described in the tutorial the designer allows to graphically build a Joram distributed architecture. It produces a3servers.xml and joramAdmin.xml configuration files. Now, it allows to automatically deploy the designed configuration using DeployWare.

This release is tagged in SVN (JORAM_DESIGNER_1_0_0).

May 10, 2010: JORAM in OW2 Open Source Cloudware Initiative.

Last week, OW2 Consortium members Bull, Orange and INRIA had announced the OW2 Open Source Cloudware Initiative at the Solutions Datacenter Management and Cloud Computing trade show in Paris. The bedrock of the OSC Initiative includes the following open source OW2 projects: CLIF, Entropy, JASMINe, JOnAS, and JORAM to provide the capability for on-demand JavaEE autonomic server provisioning according to demand fluctuations and ProActive for complementary heterogeneous capacity management.

May 07, 2010: JORAM 5.3.1 maintenance release is available.

This release introduces some improvements and bug fixes, essentially:

• A reworked PoolNetwork component with one Sender by NetSession. This optimizes performances and fixes various synchronization issues. Furthermore, SoftReferences are now used in the PoolNetwork to avoid memory errors when messages accumulate in the network.
• Interceptors can now be configured for managed connection factories.
• Bug fixes in JMS bridge allowing anew the use of persistent server (a configuration parameter is now required to enable XAConnection).
• Bug fix about destination using Timer. These destinations are now locked in memory and the Timer tasks are handled depending of the agent life-cycle.
• Potential bug fix in heart-beat handling. Previously an exception in HeartBeatTask.start method caused an Engine stop.
• Potential bug fix avoiding deadlock in AdminModule.stopServer of local server.
• Changes configuration properties naming for NGTransaction.

This version is available for download, and in Maven repository.

It is tagged in SVN (JORAM_5_3_1), the complete list of changes can be viewed either in code updates or in SVN history.

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)
