How to convert a string to a SOAPMessage in Java?

Question

I wonder is there any way to convert a string to SOAPMessage?

Let me say I have a string as follows:

String send = "

I just want to share my code snippet in Stack-Overflow, which might help some people.

SOAP-XML String with Comments

static boolean OMIT_XML_DECLARATION = true;
static String soapXML = ""
            + " "
            + "  "
            + "API Gateway Oracle SOA Security and Management"
            + "  ";

Convert SOAP-XML String to SOAP-Message Object

public SOAPMessage getSoapMessage(String xmlData, boolean isToIgnoringComments) throws Exception {
    if (isToIgnoringComments) {
        Document doc = getDocument(xmlData); // SOAP MSG removing comment elements
        xmlData = toStringDocument(doc);
    }
    
    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(xmlData.getBytes());
    MimeHeaders mimeHeaders = new MimeHeaders();
    SOAPMessage message = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(mimeHeaders, byteArrayInputStream);
    return message;
}
public static Document getDocument(String xmlData) throws Exception {
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    dbFactory.setNamespaceAware(true);
    dbFactory.setIgnoringComments(true);
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        InputSource ips = new org.xml.sax.InputSource(new StringReader(xmlData));
        Document doc = dBuilder.parse(ips);
    return doc;
}

Converting SOAP-Message Object to SOPA-XML String

public static String toStringDocument(Document doc) throws TransformerException {
    StringWriter sw = new StringWriter();
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    if (OMIT_XML_DECLARATION) {
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    } else {
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
    }
    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");

    transformer.transform(new DOMSource(doc), new StreamResult(sw));
    return sw.toString(); // sw.getBuffer().toString();
}

Full Example:

public class SOAPOperations {

    // dependency: groupId:xml-security, artifactId:xmlsec, version:1.3.0
    // dependency: groupId:xalan, artifactId:xalan, version:2.7.1
    public static void main(String[] args) throws Exception {
        
        SOAPOperations obj = new SOAPOperations();
        
        SOAPMessage soapMessage = obj.getSoapMessage(soapXML, true);
        System.out.println("SOAP Message Object:\n"+soapMessage);
        
        String soapMessageStr = obj.getSoapMessage(soapMessage);
        System.out.println("SOAP Message String:\n"+soapMessageStr);
        
        String soapBodyStr = obj.getSoapBody(soapMessage);
        System.out.println("SOAP Body String:\n"+soapBodyStr);
    }

    public String getSoapBody(SOAPMessage soapMessage) throws Exception {
        SOAPBody soapEnv = soapMessage.getSOAPBody();
        Document ownerDocument = soapEnv.extractContentAsDocument();
        String stringDocument = toStringDocument(ownerDocument);
        return stringDocument;
    }
    public String getSoapMessage(SOAPMessage soapMessage) throws Exception {
        SOAPEnvelope soapEnv = soapMessage.getSOAPPart().getEnvelope();
        Document ownerDocument = soapEnv.getOwnerDocument();
        String stringDocument = toStringDocument(ownerDocument);
        return stringDocument;
    }
}
