Another Attachment Problem

Question

I used JWSDP 2.0 to generate my client stubs from a WSDL file. I have one web service method that is supposed to allow the client to send a file as a SOAP attachment. Info on defining the WSDL for web service methods that receive attachments from the client seems to be sparse. The one example I found said to set up the WSDL like this:
<operation name="sendFile">
   <soap:operation soapAction="" />
      <input>
         <mime:multipartRelated>
            <mime:part>
               <soap:body use="literal" namespace="com.blankety.SomeWSInterface"/>
            </mime:part>
            <mime:part>
               <mime:content part="fileHandler" type="application/octet-stream" />
            </mime:part>
         </mime:multipartRelated>
      </input>
      <output>
         <soap:body use="literal" namespace="com.blankety.SomeWSInterface"/>
      </output>
</operation>Actually, the original example didn't have the namespace attribute but wscompile would not create the stub without the namespace defined. So I added that.
Anyway, the client stub for the above method gets generated fine. But at runtime, the stub throws the following exception:
javax.xml.rpc.soap.SOAPFaultException: JAXRPCTIE01:
caught exception while handling request: no attachment with id "fileHandler" found in message
     at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:528)
     at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:307)
     at com.blankety.SomeWSInterfacePortType_Stub.sendFile(SomeWSInterfacePortType_Stub.java:498)
...Some research showed that the client has to properly set the Content Id for the attachment. But I looks to me like the code IS properly setting the Content Id, according to the one source I found. Here is the addAttachment method where the id is created. The value of the part argument is "fileHandler", which is what the above Exception is complaining about:
private void addAttachment(javax.xml.soap.SOAPMessage message, Object value,
         java.lang.String mimeType, java.lang.String part) throws Exception{
      java.lang.String contentId = part + "="
            + com.sun.xml.rpc.util.JAXRPCUtils.getUUID() + "@jaxrpc.sun.com";
      javax.xml.soap.AttachmentPart _attPart = null;
      if (value == null || mimeType == null){
         return;
      if (value instanceof javax.activation.DataHandler){
         _attPart = message
               .createAttachmentPart((javax.activation.DataHandler) value);
      } else if (value instanceof javax.mail.internet.MimeMultipart){
         java.lang.String contentType =
            ((javax.mail.internet.MimeMultipart) value).getContentType();
         javax.activation.DataHandler dataHandler =
            new javax.activation.DataHandler(value, contentType);
         _attPart = message.createAttachmentPart(dataHandler);
      } else{
         _attPart = message.createAttachmentPart(value, mimeType);
      _attPart.setContentId("<" + contentId + ">");
      message.addAttachmentPart(_attPart);
   }The statement that calls this method is:
addAttachment(_state.getRequest().getMessage(),
    (Object)fileHandler,
    ((javax.activation.DataHandler)fileHandler).getContentType(),
    "fileHandler");I've run this in the debugger and can see that the attachment is created and that there is a Content Id. Debugger output:
mimeType     "text/plain" (id=74)     
part     "fileHandler" (id=81)     
contentId     "[email protected]" (id=82)     
_attPart     AttachmentPartImpl  (id=52)     
   dataHandler     DataHandler  (id=56)     
     currentCommandMap     null     
     dataContentHandler     null     
     dataSource FileDataSource  (id=84)     
          _file     File  (id=96)     
          typeMap     null     
     factoryDCH     null     
     objDataSource     null     
     object     null     
     objectMimeType     null     
     oldFactory     null     
     shortType     null     
     transferFlavors     DataFlavor[0]  (id=87)     
     headers     MimeHeaders  (id=60)     
     rawContent     null     Obviously com.sun.xml.rpc.client.StreamingSender is not finding the Content Id. But why? Is it looking in the wrong place? Or is my client stub setting it in the wrong place?
