Webobjects WebServices - howto stream large Binary Objects

I want to use webobjects  for creating webservices to send large  
binary files (eg a zipfile of 200Mb)

This works for small data objects (like a jpg of 50kB)
The problem is the data is not getting streamed, but the entire file  
is being read in memory, which causes stack overflows.

Could someone give me a hint on how I can communicate through  
webservices with large binary data objects?

This is an extract of the code I use:

WebService Consumer  (Project 1)
============================

	FileInputStream is = new FileInputStream("/path/to/file");

	NSData d = new NSData(is,1024);	 // CRASHES HERE !!!
		
	Object [] params = new Object[1];
	params[0] = d;
	
	WOWebServiceClient client = new WOWebServiceClient();
	// extra initialisation here
	
	Object result = client.invoke("FileUpload", "upload", params);




This is the WebService (Project 2)
================================
// I create a routine with an "NSData" parameter and register it as a  
webservice

WOWebServiceRegistrar.registerWebService(FileUpload.class, true);


import java.io.*;
import com.webobjects.foundation.*;

public class FileUpload {
     public static boolean upload(NSData d) {
			
		//OutputStream stream
		try {
			FileOutputStream fileOutputStream = new FileOutputStream("/tmp/ 
file");
			d.writeToStream(fileOutputStream);
			fileOutputStream.close();
		}
		catch (IOException exception) {
			// Do something with the exception
		}

	   return true;
	}
}
