Ron Sigal commented on JBREM-661:
---------------------------------

Description of duplicate issue JBREM-776:

The logical inverse of existing JBoss streams implementation is needed to stream files from the server to the client.

CLIENT:
OutputStream out = ... (ByteArrayOutputStream or FileOutputStream as needed)
remotingClient = new Client(new InvokerLocator(streamLocatorURL));
remotingClient.connect();
remotingClient.invoke(out, parameter);

SERVER:
public Object handleStream(OutputStream stream, InvocationRequest request) {
   ... get file based on request.getParameter();
   ... standard write a file to the stream
}

On the server the bean would use the parameter to determine the file requested. For example the parameter might be a primary key value to file meta data, or it could be a known filepath, or bytes read from a database. Security can be handled at the application level by the bean.

>
> As of release 2.0.0 GA, there is no way for a server to send a stream to the client (only the other way around).
> This is to request something like java.io.InputStream Client.invoke(java.lang.Object param)
> that allows for true streaming (like java.lang.Object invoke(java.io.InputStream inputStream, java.lang.Object param) does).
