wss4j scala problem

Does anyone have any experience in SOAP UserNameToken (Hash) generation?

it generates the soap headers like this:

   <wsse:Security xmlns:wsse="http://...wsssecurity...">
    <wsse:UserNameToken xmlns:wsse="http://...wsssecurity...">
    <Username xmlns="">myname</Username>
    <Password xmlns="">mypass</Password>
    </wsse:UserNameToken>
    </wsse:Security>

How do I generate the UserNameToken in the correct way (as SoapUi does automatically)?

In Java you can use WSS4J and make the header yourself?
But how can I do this in a scala file or are there any better options?

            SOAPPart soappart = message.getSOAPPart();
            SOAPEnvelope envelope = soappart.getEnvelope();
            SOAPHeader header = envelope.getHeader();
            WSSecHeader wsheader = new WSSecHeader();
            wsheader.insertSecurityHeader(soappart);
            WSSecUsernameToken token = new WSSecUsernameToken();
            token.setPasswordType(WSConstants.PASSWORD_DIGEST);
            token.setUserInfo("myuser", "mypass");
            token.build(soappart, wsheader);
