Thanks for you response. I attempted to get MTOM enabled on the server side as instructed in the link provided. Using wsprovide with the following endpoint configuration: @Remote @WebService(targetNamespace = "http://fileXfer.ws.synoran.com/") @SOAPBinding(style = SOAPBinding.Style.DOCUMENT, parameterStyle = SOAPBinding.ParameterStyle.BARE) @BindingType(value="http://schema.xmlsoap.org/wsdl/soap/http?mtom=true") public interface FileXferEndpoint { public String sendPart(Long txId, Integer partNum, Long size, DataHandler data); } I am getting the following exception: org.jboss.ws.WSException: Unsupported binding: http://schema.xmlsoap.org/wsdl/soap/http?mtom=true at org.jboss.ws.metadata.umdm.EndpointMetaData.setBindingId(EndpointMetaData.java:178) Is the documentation update to date with regards to the URL needed for the binding type to enable MTOM?
