The purpose of this project is creating an alternative SOA implementation which is lightweight, easy to use and flexible. I believe that this project is not a challenge to webservices, but it might be more suitable in some cases like RIA platforms, testing and projects where you have to work against tight schedules.

      How does this compare with DWR?

Thus developers can post additional fields to services to apply their policies to service calls.Message headers are accessible by interceptors and services.

But the framework is quite flexible and expandable.  Implementation of a single simple class is enough to have additional end points.

        Hi Martin,

        I don't know DWR in depth but I can say that the main difference is DWR is focused on AJAX, but SR mainly focuses on services and SOA. SR is not only targeting browsers, but java and other rich clients as well. Their intentions are different.

        SR focuses on :

        * Converting server side object to services
        * Service registry & service registry query
        * Managing server side objects life cycle
        * Services security
        * Message filtering mechanisms
        * End-point implementations (currently only http is available, jms is planned as target)
        * Messaging format (like SOAP)
