XML Character Encoding Using UTL_DBWS

Question

Hi,
I have a database with WINDOWS-1252 character encoding. I'm using UTL_DBWS to call a web service method which echoes a given string. For this purpose, I do the following:
DECLARE
    v_wsdl CONSTANT VARCHAR2(500) := 'http://myhost/myservice?wsdl';
    v_namespace CONSTANT VARCHAR2(500) := 'my.namespace';
    v_service_name CONSTANT UTL_DBWS.QNAME := UTL_DBWS.to_qname(v_namespace, 'MyService');
    v_service_port CONSTANT UTL_DBWS.QNAME := UTL_DBWS.to_qname(v_namespace, 'MySoapServicePort');
    v_ping CONSTANT UTL_DBWS.QNAME := UTL_DBWS.to_qname(v_namespace, 'ping');
    v_wsdl_uri CONSTANT URITYPE := URIFACTORY.getURI(v_wsdl);
    v_str_request CONSTANT VARCHAR2(4000) :=
'<?xml version="1.0" encoding="UTF-8" ?>
<ping>
    <pingRequest>
        <echoData>Dev Team üöäß</echoData>
    </pingRequest>
</ping>';
    v_service UTL_DBWS.SERVICE;
    v_call UTL_DBWS.CALL;
    v_request XMLTYPE := XMLTYPE (v_str_request);
    v_response SYS.XMLTYPE;
BEGIN
    DBMS_JAVA.set_output(20000);
    UTL_DBWS.set_logger_level('FINE');
    v_service := UTL_DBWS.create_service(v_wsdl_uri, v_service_name);
    v_call := UTL_DBWS.create_call(v_service, v_service_port, v_ping);
    UTL_DBWS.set_property(v_call, 'oracle.webservices.charsetEncoding', 'UTF-8');
    v_response := UTL_DBWS.invoke(v_call, v_request);
    DBMS_OUTPUT.put_line(v_response.getStringVal());
    UTL_DBWS.release_call(v_call);
    UTL_DBWS.release_all_services;
END;
/Here is the SERVER OUTPUT:

   </pingResponse>
</ns0:pingResponse>As you can see the character encoding is broken in the request and in the response, i.e. the SOAP encoder does not take into consideration the UTF-8 encoding.
I tracked down the problem to the method oracle.jpub.runtime.dbws.DbwsProxy.dom2SOAP(org.w3c.dom.Node, java.util.Hashtable); and more specifically to the calls of oracle.j2ee.ws.saaj.soap.soap11.SOAPFactory11.
My question is: is there a way to make the SOAP encoder use the correct character encoding?
Thanks a lot in advance!

I found a workaround of the problem:
    v_response := XMLType(v_response.getBlobVal(NLS_CHARSET_ID('CHAR_CS')), NLS_CHARSET_ID('AL32UTF8'));Ugly, but I'm tired of decompiling and debugging Java classes ;)
