The Synapse project will create a robust, lightweight implementation of a highly scalable and distributed service mediation framework based on Web services specifications.
For more information, see:
Synapse is a mediation framework for Web Services. Synapse allows messages flowing through, into, or out of an organization to be mediated.
The configuration language and its syntax is available at http://wiki.apache.org/incubator/Synapse/SynapseConfigurationLanguage
Synapse, incidentally, is pronounced "sine-apse", and not "sin-apse".
Synapse is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Web Services PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
We have released the second Milestone M2. The release will support:
A streamlined configuration model and a new XML syntax
Concept of Endpoints
Global and message context based 'properties', and a new XPath extention function synapse:get-property() to read them
New mediators - Switch & Validate
Enhanced and streamlined mediators - send, drop, log, makefault, transform, header, filter, class, set-property, sequence, in & out
Message correlation support
Enhanced Spring support
Synapse initialization on Axis2 startup
Sample applications and configurations demonstrating most of the above features
Enhanced documentation
