What JORAM is

JORAM is an open-source Java implementation of the JMS API and 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 tests it with LTS versions 11, 17, and 21. The broker supports store-and-forward delivery, clustered destinations, and master/slave high availability with replicated data stores. JORAM can operate as a standalone server, be embedded in another product, or connect to a JEE application server through its JCA adapter. It runs as OSGi bundles or a classic Java program, with services such as the command line interface and web console configurable during operation. Administration options include JMX, JMS and REST APIs, XML configuration scripts, and a web console. The project describes authentication, authorization, and encryption support, with TCP and SSL transport options. Documented bridges and extensions cover JMS, AMQP, mail, URL, JMX, and FTP. C and C++ client APIs are available, and other-language clients can connect through Stomp Connect. JORAM is free under LGPL 2.1 or later and distributed through OW2.

Who it suits

JORAM suits developers and operators building Java-based messaging systems who need self-hosted deployment and configurable delivery. It can also serve products or JEE application servers through embedding or its JCA adapter.

Getting started

Open the JORAM website
Download source, binary, client, Javadoc, or application-server adapter packages
Install on Linux or Windows with Java 11 through 21
Run it as a standalone server, embedded component, or JEE application-server integration
Configure services through the command line, web console, XML scripts, JMX, REST, or the JMS management API
Connect clients through JMS, AMQP, STOMP, HTTP/REST, SOAP, C, C++, or Stomp Connect

Verdict

JORAM offers multiple deployment and administration choices alongside clustered messaging and high-availability options. Its Java 11 minimum is a key compatibility constraint for older environments.
