How to change the namespace position in the generate xml message (SOAP message)?

[Yuval Zou]

Hi,

Recently, I'm working on a web services client using CXF. But some request
messages can't be parsed by the web services server. I found the problem is
related to the namespace and prefix.
The correct message:
<?xml version="1.0" encoding="UTF-8"?>
<CreateItemRequest xmlns="http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema";>
 <AuthenticationData>
  <ServerDef>
   <ServerName>icmnlsdb</ServerName>
  </ServerDef>
  <LoginData>
   <UserID>icmadmin</UserID>
   <Password>********</Password>
  </LoginData>
 </AuthenticationData>
 <Item>
  <ItemXML>
   <CLAIM_1047 DATE_1047="2004-01-27" CLAIMNO_1047="1234" DESC_1047="This is
a claim regarding the accident.3">
    <properties xmlns="http://www.ibm.com/xmlns/db2/cm/api/1.0/schema";
type="document"/>
    <VEHICLE_1047 VIN_1047="38">
     <OWNER_1047 FNAME_1047="Ben" LNAME_1047="Dover"/>
     <OWNER_1047 FNAME_1047="Eileen" LNAME_1047="Dover"/>
    </VEHICLE_1047>
    <VEHICLE_1047 VIN_1047="34">
     <OWNER_1047 FNAME_1047="I.P." LNAME_1047="Freely"/>
    </VEHICLE_1047>
    <ICMBASE>
     <resourceObject xmlns="http://www.ibm.com/xmlns/db2/cm/api/1.0/schema";
MIMEType="image/tiff">
      <label name="base 1"/>
     </resourceObject>
    </ICMBASE>
   </CLAIM_1047>
  </ItemXML>
 </Item>
</CreateItemRequest>
The namespace http://www.ibm.com/xmlns/db2/cm/api/1.0/schema was put in the
element that needs it in this correct message.

The mesage can't be parsed by server (sent by CXF):
<?xml version="1.0" encoding="UTF-8"?>
<CreateItemRequest xmlns:ns2="http://www.ibm.com/xmlns/db2/cm/api/1.0/schema";
xmlns="http://www.ibm.com/xmlns/db2/cm/beans/1.0/schema";>
 <AuthenticationData>
  <ServerDef>
   <ServerName>icmnlsdb</ServerName>
  </ServerDef>
  <LoginData>
   <UserID>icmadmin</UserID>
   <Password>********</Password>
  </LoginData>
 </AuthenticationData>
 <Item>
  <ItemXML>
   <CLAIM_1047 DESC_1047="This is a claim regarding the accident.3"
CLAIMNO_1047="1234" DATE_1047="2004-01-27">
    <ns2:properties type="document"/>
    <VEHICLE_1047 VIN_1047="38">
     <OWNER_1047 LNAME_1047="Dover" FNAME_1047="Ben"/>
     <OWNER_1047 LNAME_1047="Dover" FNAME_1047="Eileen"/>
    </VEHICLE_1047>
    <VEHICLE_1047 VIN_1047="34">
     <OWNER_1047 LNAME_1047="Freely" FNAME_1047="I.P."/>
    </VEHICLE_1047>
    <ICMBASE>
     <ns2:resourceObject MIMEType="image/tiff">
      <ns2:label name="base 1"/>
     </ns2:resourceObject>
    </ICMBASE>
   </CLAIM_1047>
  </ItemXML>
 </Item>
</CreateItemRequest>

The namespace http://www.ibm.com/xmlns/db2/cm/api/1.0/schema was put in the
root element.

Is there anyone who knows how to configure CXF to generate the XML message
in accordance with the first style? Or is there possible to manually modify
the generated message using out Interceptor?
Actually, I have tried to use interceptor the modify the output stream:
public StreamInterceptor() {
        super(Phase.PRE_STREAM);
        addBefore(SoapPreProtocolOutInterceptor.class.getName());
}

   public void handleMessage(Message message) {
     OutputStream os = message.getContent(OutputStream.class);
        CachedStream cs = new CachedStream();
        message.setContent(OutputStream.class, cs);

        message.getInterceptorChain().doIntercept(message);

        try {
            cs.flush();
            CachedOutputStream csnew = (CachedOutputStream)
message.getContent(OutputStream.class);
//            FileOutputStream fileOut = new
FileOutputStream("D:\\test.txt");
//            CachedOutputStream.copyStream(csnew.getInputStream(), fileOut,
1024);

            StringBuilder sb = new StringBuilder();
            csnew.writeCacheTo(sb);

            String tmpXML = sb.toString();
            System.out.println("#####OLD####" + tmpXML);
            while (tmpXML.indexOf("<ns2:")!=-1){
             String subTmp = tmpXML.substring(tmpXML.indexOf("<ns2:"));
             subTmp = subTmp.substring(1, subTmp.indexOf(" "));
             tmpXML = tmpXML.replaceAll(subTmp, subTmp.substring(4) + " " +
"xmlns=\"http://www.ibm.com/xmlns/db2/cm/api/1.0/schema\<http://www.ibm.com/xmlns/db2/cm/api/1.0/schema/>"
");
             System.out.println("#####FIXED#######" + tmpXML);
            }

            InputStream in = new ByteArrayInputStream(tmpXML.getBytes());

            BufferedOutputStream bos = new BufferedOutputStream(os);
            CachedOutputStream.copyStream(in, bos, 1024);

            cs.close();
            in.close();
//            fileOut.close();
            bos.close();
            os.flush();

            message.setContent(OutputStream.class, os);
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }

But the above code can't handle the message stream with MTOM attachements.
It can't get the OutputStream at all. I don't know the reason.

Your help will be really appreciated. Thanks in advance!
