## org.springframework.remoting.caucho
Class HessianServiceExporter

    java.lang.Object
      org.springframework.remoting.support.RemotingSupport
          org.springframework.remoting.support.RemoteExporter
              org.springframework.remoting.caucho.HessianExporter
                  org.springframework.remoting.caucho.HessianServiceExporter

All Implemented Interfaces:
  Aware, BeanClassLoaderAware, InitializingBean, HttpRequestHandler

    public class HessianServiceExporter

extends HessianExporter
implements HttpRequestHandler

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

Note: Spring also provides an alternative version of this exporter, for Sun's JRE 1.6 HTTP server: `SimpleHessianServiceExporter`.

Hessian is a slim, binary RPC protocol. For information on Hessian, see the Hessian website. Note: As of Spring 3.0, this exporter requires Hessian 3.2 or above.

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