As a standalone software, JORAM has been downloaded more than 22,000 times

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

JORAM is an open source software released under the LGPL license.

Specification

JORAM provides full support to JMS 1.1:

Unified interfaces for the Point-to-Point (PTP) and Publish/Subscribe (Pub/Sub) messaging models
AND still the semantically specific PTP and Pub/Sub interfaces
Full backward compatibility with JMS 1.0.2b compliant applications
Local, TCP and SOAP (HTTP/XML) client-server communication protocols
Message persistence and guarantee of delivery
Hierarchical topics
Message selection
Message prioritization
A JCA 1.5 Resource Adapter

JORAM also includes the following extra-features:

A persistent, reliable and distributed JNDI server
A configurable dead message queue
Load balancing through clustered topics and queues
Monitoring methods
A bridge feature allowing to link JORAM to any JMS compliant messaging platform
Client libraries allowing J2ME applications to access the JORAM platform in a JMS 1.1 "way"
A graphical administration and monitoring tool
High Availability provides the active replication of Joram servers and underlying agent servers, as well as replicated JORAM clients. It transparently handles network handover and server failover. This version currently relies on the use of JGroups.
Dynamic Configuration,provide facilities to remotely add and remove Joram servers dynamically through the Administration API of JORAM. This great feature, combined with updated JMX implementation, initiates a new set of management facilities in JORAM
