My soap client recives the error 

Attachment tag "item" refers to a Mime attachment with label "cid:12568800.1054615058828.apache-soap.%B1%E8%C8%F1%C1%A4102179" which could not be found. 


The SOAP Client is sending a Vector that consists of 3 elements 

File Name 
Checksum for the file 
DataHandler for the file 

Here is the relevant code: 


                String encodingStyleURI = Constants.NS_URI_SOAP_ENC;

                Response resp = null; 
                Parameter ret = null; 

                XferResponse myResp = new XferResponse(); 
                try { 
                        url = new URL(targetURL); 
                } 
                catch (Exception e) {

targetURL); 
                        System.err.print (" remoteURI = " + remoteURI);

                        myResp.errorCode = 1;

                        return (myResp); 
                } 

                if (parmVector.size() > 0) {

Since then, I have tried to force the character encoding to UTF 8 on the 
client using:

(and replacing the Call initializer)


                        ctx = new SOAPContext();
                        try {
                                ctx.setRootPart ("X", "text/xml; 
charset=utf-8");
                        }
                        catch (Exception xxx) {
                                xxx.printStackTrace();
                                myResp.errorCode = 99;
                                myResp.errorMessage = "Unable to set 
charset to utf-8";
                                return (myResp);
 
                        }
                        /*
                        Call call = new Call();
                        call.setSOAPMappingRegistry(smr);
                        call.setTargetObjectURI(remoteURI);
                        call.setMethodName(methodName);
                        call.setEncodingStyleURI(encodingStyleURI);
                        call.setParams(params);
                        */
                        Call call = new Call (remoteURI, methodName, 
params, null, encodingStyleURI, ctx);

This code (either form) works in the US.  Problem occurs in Korea 

OS Is Windows XP for SOAP Client

SOAP/Tomcat runs as a service on Windows XP


Any and all help greatly appreciated.
