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?
