Apache CXF is an open source services framework. CXF helps you build and develop services using frontend programming APIs, like JAX-WS. These services can speak a variety of protocols such as SOAP, XML/HTTP, Restful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI.
SOAP over JMS offers an alternative messaging mechanism to SOAP over HTTP. SOAP over JMS offers more reliable and scalable messaging support than SOAP over HTTP.
SOAP over JMS specification([WWW] http://www.w3.org/TR/soapjms/) is aimed at a set of standards for the transport of SOAP messages over JMS (Java Message Service). The main purpose is to ensure interoperability between the implementations of different Web services vendors.
CXF does support SOAP over JMS, but it does not meet the current draft specification defined at [WWW] http://www.w3.org/TR/soapjms/ and instead uses some proprietary formats, headers, url formats, etc. This project would update the SOAP/JMS support in CXF to be completely specification compliant.
Upon sucessful completion of the SOAP/JMS project, CXF will become one of the very first Open Source implementations of the SOAP/JMS specificiation.
