JORAM: Java (TM) Open Reliable Asynchronous Messaging

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 D.T. 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"
• Client libraries allowing C or C++ applications to access the JORAM platform in a JMS 1.1 "way"
• 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 provides 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.
