A review of Open source EAI solutions written in Java, primarily Message Oriented Middleware (i.e. MOM) brokers that perform routing, brokering and transformations. For ETL functionality see “Open Source ETL“. Here’s the list:

  • Proteus – Proteus is a framework for creating messaging applications, and a message broker built upon that framework. Proteus has adapters that allow databases, message queues, ftp servers, email and other message sources and sinks to be addressed in a simple, uniform fashion. (GPL)
  • OpenEAI – The purpose of the OpenEAI Project is to discover and document the controlling dynamics, principles, and practices of enterprise application integration and to present, implement, and promote those findings. The OpenEAI Project presents findings in the form of the OpenEAI methodology and OpenEAI software for implementing integrations. (LGPL)
  • XMLBlaster – XmlBlaster is a publish/subscribe and point to point MOM server which exchanges messages between publishers and subscribers. The message is described with XML-encoded meta information. Messages may contain everything, GIF images, Java objects, Python scripts, XML data, a word document, plain text. Communication with the server is based on CORBA (using JacORB) or RMI or XmlRpc, clients are free to choose their preferred protocol. Other protocols like email, socket or SOAP may be plugged in. (LGPL)
  • OpenQueue – OpenQueue is an open protocol for publish-and-subscribe message queuing. This enables language-independent, loosely-coupled, asynchronous communications between applications running on different machines.
  • Elemenope -elemenope llows one to easily create a large scale multi-platform application to do messaging or transaction processing. It abstracts away all of the connectivity issues when dealing with or designing such a project. It uses Java Message Service [JMS] for messaging, and currently utilizes IBM MQSeries [WebSphereMQ] for a Message Oriented Middleware [MOM]. It also has built-in mainframe connectivity classes for use when connecting to a mainframe running IBM MQSeries with the IMS Adapter or IMS Bridge. elemenopexe2x84xa2 has been in development for over three years. It and some of its precursors are currently in production use within several companies large and small. (GPL)
  • MessageForge – The framework was conceived and created during the development of an online trading system for a major bank on Wall Street. The project made heavy use of TIBCO/RV. Features include transparent message definitions, automatic generation of JAVA classes from XML definitions, a type-safe messaging JAVA API, run-time message validation, services to marshal/unmarshal messages, uniform message definitions across all tiers and high performance. (BSD)
  • SolAce – Secure Transport of Transactions across any network. Reliable delivery, tamperproof and encrypted messages, and signed receipts proving message delivery to the originator of the message. Never lose an e-mail message or FTP transaction again. Integrates seamlessly with almost all FTP servers, EDI gateways, and claims adjudication systems. Transports any type of file securely and reliably, not limited to HIPAA or EDI transactions. Secure (SSL) web-based administration and remote mailbox access. Security features to foil hacker reconnaissance and attacks. (GPL)
  • jEngine – JEngine uses JBossxe2x80x99 core for database persistence, transaction support, messaging and
    integration of components based on Java Management Extensions (JMX) specification.
    JEnginexe2x80x99s JMX components currently include TCP/IP HL7 2.x client and server components.
    Due to the adoption of the HL7 2.x standard within healthcare organizations and the singular
    focus of the HL7 organization on the interface requirements of the entire health care industry,
    these components were the first to be developed. Internal JEngine messaging uses the Java Message Service (JMS), which provides a reliable
    means for the asynchronous exchange of data within the healthcare enterprise. The JEngine core utilizes standards-based XML/XSLT transformations for message structure
    manipulation. (LGPL)
  • S-integrator – A service-oriented integration server that hosts Service Stores which authorize, monitor, manage and run services while making them available through web services, HTTP and other protocols.

Administration is performed using a web browser or cell phone that accesses the embedded web server. Service Flows provide process automation and hot deployment is supported. S-integrator is single-source, small footprint and only requires JRE 1.2 and a database with JDBC driver.
  • Mule – Mule is a simple yet robust and highly scalable component broker and services framework. Mule is a light-weight, event-driven component technology; it is highly scalable, using ideas from SEDA; designed around the ESB (Enterprise Service Bus); components managed by mule can be Beans, EJBs, IoC3 compatible components, Servlets, POJOs, etc; Mule builds on existing best-of-breed lightweight containers and gives you the option to pick an choose which framework components you wish to use and connectors for JMS, HTTP, TCP, SMTP, POP3, FILE, XML-RPC and VM.
  • JyRetic – Retic was initially developped in Python, but an EAI server means a connectivity with as many protocols and products as possible. Python, lacks connectivity with databases and MOMs. That is why Retic was translated to Jython : JyRetic, giving it JDBC and JMS connectivity. The Java Service Wrapper from Tanuki Software is now used to control JyRetic.
  • OSMQ – Open Source Message Queue (OSMQ)TM is an advanced, pure Java, asynchronous message router, message broker and message middleware framework developed by MQue Systems. OSMQ was designed for high performance, high reliability, and ease of use, with an interface that is less complex than JMS.
