/**
* HTTP request handler that exports the specified service bean as
* Burlap service endpoint, accessible via a Burlap proxy.
* Designed for Sun's JRE 1.6 HTTP server, implementing the
* {@link com.sun.net.httpserver.HttpHandler} interface.
*
* Burlap is a slim, XML-based RPC protocol.
* For information on Burlap, see the
* Burlap website.
* This exporter requires Burlap 3.x.
*
*
Note: Burlap services exported with this class can be accessed by
* any Burlap client, as there isn't any special handling involved.
