Java EE (Java Enterprise Edition) General Discussion

Hi,

I'm using the SAAJ API to send a message with an attachment to a .Net web service. I followed the example in the J2EE tutorial and my code manages to call the web service correctly when I don't include an attachment, however when I include an attachment it returns the following error:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Header><wsu:Timestamp xmlns:wsu="http://schemas.xmlsoap.org/ws/2002/07/utility"><wsu:Created>2005-06-01T19:43:39Z</wsu:Created><wsu:Expires>2005-06-01T19:48:39Z</wsu:Expires></wsu:Timestamp></soap:Header><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>System.Web.Services.Protocols.SoapHeaderException: The message is not a valid XML message ---> System.Xml.XmlException: The data at the root level is invalid.

at System.Xml.XmlDocument.Load(XmlReader reader)
at Microsoft.Web.Services.SoapEnvelope.Load(Stream stream)
...


Here is the code:

// Prepare the message
			MessageFactory factory = MessageFactory.newInstance();
			SOAPMessage message = factory.createMessage();
			
			MimeHeaders hd = message.getMimeHeaders();
			hd.addHeader("SOAPAction", "http://tempuri.org/EchoString");
			
			SOAPPart soapPart = message.getSOAPPart();
			SOAPEnvelope env = soapPart.getEnvelope();

SOAPBody body = message.getSOAPBody();
			SOAPFactory soapFactory = SOAPFactory.newInstance();
			Name bodyName = soapFactory.createName( "EchoString", "", "http://tempuri.org/" );
			SOAPBodyElement bodyElement = body.addBodyElement( bodyName );
			Name name = soapFactory.createName("param");
			SOAPElement param = bodyElement.addChildElement( name );
			param.addTextNode( "ParamValue");

AttachmentPart ap1 = message.createAttachmentPart("Attachment", "text/plain");
			message.addAttachmentPart( ap1 );

// Send the message
			SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
			SOAPConnection soapConnection = soapConnectionFactory.createConnection();
			
			URL endPoint = new URL( "http://localhost/WSEcho/Echo.asmx" );
			SOAPMessage response = soapConnection.call( message, endPoint );

Anybody seen this error?

Thanks in advance.
