Hessian with large binary data

I could not understand how to implement this....Can anybody help me..

Hessian with large binary data
----------------------------------
OutputStream os = conn.getOutputStream();

HessianOutput out = new HessianOutput(os);
out.startCall("download");
out.writeString("my-file.txt");
out.completeCall();

InputStream is = conn.getInputStream();

HessianInput in = new HessianInput(is);

in.startReply();

InputStream is = in.readInputStream();

... // save the input stream data somewhere

in.completeReply();

Thank You.

For info in the Hessian API itself, have a look at www.caucho.com. Hessian usage with Spring is usually done using the HessianServiceExporter in combination with the HessianProxyFactoryBean. Have a look in the remoting docs to see how that works. Also have a look at the following post:
