/**
* Servlet-API-based HTTP request handler that exports the specified service bean
* as Burlap service endpoint, accessible via a Burlap proxy.
*
* <p><b>Note:</b> Spring also provides an alternative version of this exporter,
* for Sun's JRE 1.6 HTTP server: {@link SimpleBurlapServiceExporter}.
*
* <p>Burlap is a slim, XML-based RPC protocol.
* For information on Burlap, see the
* <a href="http://www.caucho.com/burlap">Burlap website</a>.
* This exporter requires Burlap 3.x.
*
* <p>Note: Burlap services exported with this class can be accessed by
* any Burlap client, as there isn't any special handling involved.
