I need to be able to clone a SOAPMessage object, but it doesn't implement Clonable. How can I do this?

问题

I have a "skeleton" SOAPMessage object, which will be the starting point of other SOAPMessages. I want to be able to clone the base SOAPMessage, so I can then fill it with the information needed and send it, and do this every time I need to send a SOAPMessage.
How can I clone a SOAPMessage, since it doesn't implement Clonable? I've been looking for other frameworks and found Apache CXF, which has a SoapMessage class that is Clonable. However, I can't use it because the WSDL I'm using is old-style (encoded, or something) and doesn't allow me to import the WSDL into Java classes...
Any suggestions? Thanks in advance!

You can simply change SOAPMessage to string, and use this string as a source for new instance message.

Example below.

public static String messageToString(SOAPMessage soap) throws  SOAPException, IOException{
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    soap.writeTo(stream);
    String message = new String(stream.toByteArray(), "utf-8");
    return message;
}

public static SOAPMessage stringToMessage(String soap) throws IOException, SOAPException{
    InputStream inputStream = new ByteArrayInputStream(soap.getBytes());
    SOAPMessage soapMessage = MessageFactory.newInstance().createMessage(null, inputStream);
    return soapMessage;
}

SOAPMessage sourceMessage; //some message to clone need to initiate it
SOAPMessage clonedMessage = MessageFactory.newInstance().createMessage();
clonedMessage = stringToMessage(messageToString(sourceMessage));

Work for me.
