Servlet-API-based HTTP request handler that exports the specified service bean as Hessian service endpoint, accessible via a Hessian proxy.

Hessian is a slim, binary RPC protocol. For information on Hessian, see the Hessian website. Note: As of Spring 4.0, this exporter requires Hessian 4.0 or above.

Hessian services exported with this class can be accessed by any Hessian client, as there isn't any special handling involved.
