"Holodeck", an open source version of ebXML Messaging V3 (http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/core/os/ebms_core-3.0-spec-os.pdf ) and its AS4 profile (http://www.oasis-open.org/apps/org/workgroup/ebxml-msg-as4/document.php?document_id=35344) is now available on Sourceforge at http://holodeck-b2b.sourceforge.net/, with main on-line documentation page directly accessible at: http://holodeck-b2b.sourceforge.net/docs/
It comes with a scalable architecture: datastore for messages (JDO by default, a MySQL pre-configured option, and interfaces to other databases), and streaming for large messages (based on Axis2 streaming).
The project is funded and maintained by Fujitsu America, Inc. This package comes with a "no coding necessary" out-of-the-box experience and tutorials, allowing you to deploy and test without having to write code up-front, using a directory system as application layer substitute to store as files elements of messages to be sent, and to receive them.Developers can download binaries and source code, and get a fresh copy directly from "Subversion" versioning system by issuing the following command (e.g. on a DOS window, provided they have installed a Subversion Client on their machine such asTortoiseSVN ):
