What JORAM is

JORAM is free, open-source Java software that implements the JMS API as distributed message-oriented middleware. It supports JMS 1.1, JMS 2.0, and Jakarta/JMS 3.0, and is compatible with Java 11 through 21; the project says it tests LTS versions 11, 17, and 21. It can run as a standalone messaging server, be embedded in another product, or connect to a JEE application server through its JCA adapter. The broker supports store-and-forward delivery, clustered destinations, and master/slave high availability with replicated data stores. JORAM can run as OSGi bundles or as a classic Java program, with services such as its command line and web console configurable while running. Administration options include JMX, management and REST APIs, XML scripts, and a web console. Security support includes authentication, authorization, and encryption, with TCP or SSL transport. Documented modules cover JMS, AMQP, mail, URL, JMX, and FTP. C and C++ client APIs are available, as is Stomp Connect for clients in other languages. JORAM is distributed through OW2 and designed by ScalAgent DT.
