WHAT IS JAmba?
Simple JMS Message Bridging

After searching the net for a replacement for the bloated message clustering package for JBoss to no avail, JAmba was born.

JAmba is a simple JMS queue routing service. Messages in local Queue A can be routed to local Queue B or, through the use of jgroups, can be sent to remote Queue A or B. This package has proven invaluable in environments that have heavy JMS queues and heavy Traffic. JAmba allows you to push your JMS messages to another, lower traffic, machine for processing... and thus, allowing the primary machine to handle the traffic.

The Beauty is in the simplicity and execution. Queues can be easily reassigned as a provider or subscriber with a simple change in an xml file in the package. This allows for easy load balancing, changes, and setup.
