[jboss-user] [JBossWS] - Large File transfer from WS Client

[bblasko]

I have a simple WS that uses MTOM/XOP.   I'm using JBossAS 4.0.5 and JBossWS 2.0.1 GA.

I have the following annotations on the service class

@WebService(name="E2PIService", serviceName="E2PIService")
  | @BindingType(value=javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_MTOM_BINDING)
  | @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
  | 

and this is the simple WebMethod signature

@WebMethod(operationName="transferFile", action="transferFile")
  |          @XmlMimeType("application/octet-stream")
  | 	public long transferFile(@XmlMimeType("application/octet-stream")javax.activation.DataHandler data)
  | 
When I invoke this service using a client, it works OK with small files but I get OutOfMemory exceptions on large files.  
I do call setMTOMEnabled(true) on the client side and verified the data is being encoded correctly.

  | SOAPBinding binding = (SOAPBinding)((BindingProvider)service).getBinding();
  | binding.setMTOMEnabled(true);
  | 
  | FileDataSource fds = new FileDataSource(new File("/bigData.dat"));
  | long d = service.transferFile(new DataHandler(fds));
  | 

It appears that the client is not streaming the data.    If I do the reverse where I send a file from the server to client, it does appear to correctly stream the data.

How can I enable the client to perform streaming of DataHandler type parameters?
