All Implemented Interfaces:

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.

This exporter will work with both Hessian 2.x and 3.x (respectively Resin 2.x and 3.x), autodetecting the corresponding skeleton class. As of Spring 2.0, it is also compatible with the new Hessian 2 protocol (a.k.a. Hessian 3.0.20+), while remaining compatible with older versions.

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