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

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((a)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?
