We have this webservice created with jax-ws
@WebService(name = "Mywebser", targetNamespace = "http://namespace")
@MTOM(threshold = 2048)
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public class Mywebser {
@WebMethod(operationName = "doStreaming", action = "urn:doStreaming")
@WebResult(name = "return")
public ResultInfo doStreaming(String username, String pwd, @XmlMimeType("application/octet-stream") DataHandler data, boolean overw){
...
}
}
The generated client side looks like this:
@WebMethod(action = "urn:doStreaming")
@WebResult(targetNamespace = "")
@RequestWrapper(localName = "doStreaming", targetNamespace = "http://namespace", className = "com.mypack.client.doStreaming")
@ResponseWrapper(localName = "doStreamingResponse", targetNamespace = "http://namespace", className = "com.mypack.client.doStreamingResponse")
public ResultInfo doStreaming(
@WebParam(name = "arg0", targetNamespace = "")
String arg0,
@WebParam(name = "arg1", targetNamespace = "")
String arg1,
@WebParam(name = "arg2", targetNamespace = "")
DataHandler arg2,
@WebParam(name = "arg3", targetNamespace = "")
boolean arg3);
By using it this way it uses streaming properly (verified we can pass an argument of 80mb when the jvm had less allowed.
MywebserService serv = ...;
Mywebser wso = serv.getMywebserPort(new MTOMFeature());
Map<String, Object> ctxt = ((BindingProvider) wso).getRequestContext();
ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
DataHandler dataHandler = new DataHandler(new FileDataSource("c:\\temp\\A.dat"));
arcres = wso.doStreaming("a", "b", dataHandler, true);
We generate a clienet for .net, with VS2008, using "Add Web Reference", we get this C# code:
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("urn:doStreaming",RequestNamespace="http://namespace",ResponseNamespace="http://namespace",Use=System.Web.Services.Description.SoapBindingUse.Literal,ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("return",Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
public ResultInfo doStreaming(
[System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg0,
[System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg1,
[System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified,DataType="base64Binary")] byte[] arg2,
[System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] bool arg3)
Apparently this is not using streaming? The type base64Binary of arg2 seems not the right one? In java it's a DataHandler. By testing it with low memory on the java side we can see it is not using streaming as it fails with OOM.
Does someone knows if this is possible, and if so how?
Our environment:
server: jdk1.6, jaxws 2.1.7
client: C# 2.0, visual studio 2008
