Hi everyone. I want to have a webservice client that reads in a file (could be everything) and sends it to my webservice over SOAP with Attachments. I am able to create the sources and everything for the client directly from the wsdl. The message when sending is created as follows:

POST /ftpSoap/ HTTP/1.1
SOAPAction: "[removedNS]/putFile"
Content-Type: multipart/related; boundary="uuid:5828c7f2-7512-4fd9-b435-bca57a6205f7"
Accept: text/xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
User-Agent: JAX-WS RI 2.1.4-b01-
Host: [removedHostname]:12345
Connection: keep-alive
Content-Length: 658920

--uuid:5828c7f2-7512-4fd9-b435-bca57a6205f7
Content-Type: text/xml

<?xml version="1.0" encoding="UTF-8"?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><PutRequest xmlns="[removedNS]/wsdl"><File folder="componentTest" name="Browser282b2.zip"/></PutRequest></S:Body></S:Envelope>
--uuid:5828c7f2-7512-4fd9-b435-bca57a6205f7
Content-Id:<data=f01fad99-4d00-40a5-88f2-80f9612ea06c@jaxws.sun.com>
Content-Type: application/binary
Content-Transfer-Encoding: binary

[binary data begins here]

To me this looks like it should. But back to the problem: When on the server side jax-ws tries to read the message (create the envelope object), I get the following error message:

java.io.IOException: Unexpected characters before XML declaration
 at com.sun.xml.messaging.saaj.util.XMLDeclarationParser.parse(XMLDeclarationParser.java:152)
at com.sun.xml.messaging.saaj.soap.SOAPPartImpl.lookForXmlDecl(SOAPPartImpl.java:670)

Can anybody tell me, why I get this error? Should I have to tell the SOAP Body, or SOAP message object somehow, that it is multipart? but there is no method to do so. I am a bit desperate, since you can not really debug this.

The Code on the Server looks like this:

SOAPMessage soapMessage = MessageFactory.newInstance().createMessage(new
MimeHeaders(),request.getInputStream());
SOAPPart soapPart = message.getSOAPPart();
SOAPBody soapBody = soapPart.getEnvelope().getBody();

Do I have to set the MimeHeaders in a different way? Do I have to manually extract the SOAP part from the request? OR is it in the end just an encoding problem?

Any help is greatly appreciated.
Thanks Alex

I was able to find the problem myself!

this was the problem:

MessageFactory.newInstance().createMessage(new MimeHeaders(),request.getInputStream());

you need to set the headers from the HTTP Request.
I did so with:

MimeHeaders soapHeader = new MimeHeaders();
          
Enumeration<String> httpReqHeaders = request.getHeaderNames();
while(httpReqHeaders.hasMoreElements()) {
  String actHeader = httpReqHeaders.nextElement();
  soapHeader.addHeader(actHeader, request.getHeader(actHeader));
}

MessageFactory.newInstance().createMessage(soapHeader,request.getInputStream());
