I'm looking for Java/Web Services experts that will provide me with feedback regarding XINS, our Web Services framework. We believe XINS could be a major player in the field of RPC, Web Services and ESB technologies, but we would like to hear what others think.
XINS has been under development for over 3 years and has been open-sourced.
Initially, XINS was just a toolbox+framework for REST-style RPC applications. Since the recently released 1.3.0 version it also supports XML-RPC and SOAP: http://xins.sourceforge.net/
