JORAM stands for Java Open Reliable Asynchronous Messaging and it's an Open Source JMS provider. It fully implements JMS 1.0.2b specifications.
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
Here are some key features of "JORAM":
· 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
· 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
