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.
