getSOAPBody returns NULL whereas SOAPResponse.writeTo prints the whole message, Strange?

Question

I am providing a java code which i found on here somewhere on stack overflow and i want to use something similar for my purpose. This code works alright but there is a persistent issue that i face. Check the sys outs i have done in the code. The first 2 sys outs that i print to get the SOAP body of the response return me a null whereas when i try to print the whole response it prints accurately. Its very strange.

Does anyone know why this happens and how to fix it. I am using JDK 1.7

import javax.xml.soap.MimeHeaders;
import javax.xml.soap.SOAPBody;

public class SOAPClientSAAJ {

public static void main(String args[]) throws Exception {
    // Create SOAP Connection
    SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
    SOAPConnection soapConnection = soapConnectionFactory.createConnection();

    // Send SOAP Message to SOAP Server
    String url = "http://ws.cdyne.com/emailverify/Emailvernotestemail.asmx";
    SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);

    System.out.println("Body");

    // print SOAP Response
    System.out.print("Response SOAP Message:");

   System.out.println("SOAP Body 2= " + soapResponse.getSOAPBody());

   System.out.println("SOAP Body 2=" + soapResponse.getSOAPPart().getEnvelope().getBody());

    soapResponse.writeTo(System.out);


    soapConnection.close();
}

private static SOAPMessage createSOAPRequest() throws Exception {
    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage soapMessage = messageFactory.createMessage();
    SOAPPart soapPart = soapMessage.getSOAPPart();

    String serverURI = "http://ws.cdyne.com/";

    // SOAP Envelope
    SOAPEnvelope envelope = soapPart.getEnvelope();
    envelope.addNamespaceDeclaration("example", serverURI);

    /*

                <example:email>mutantninja@gmail.com</example:email>
                <example:LicenseKey>123</example:LicenseKey>
            </example:VerifyEmail>
        </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>
     */

    // SOAP Body
    SOAPBody soapBody = envelope.getBody();
    SOAPElement soapBodyElem = soapBody.addChildElement("VerifyEmail", "example");
    SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("email", "example");
    soapBodyElem1.addTextNode("mutantninja@gmail.com");
    SOAPElement soapBodyElem2 = soapBodyElem.addChildElement("LicenseKey", "example");
    soapBodyElem2.addTextNode("123");

    MimeHeaders headers = soapMessage.getMimeHeaders();
    headers.addHeader("SOAPAction", serverURI  + "VerifyEmail");

    soapMessage.saveChanges();


    /* Print the request message */
    System.out.print("Request SOAP Message:");
    soapMessage.writeTo(System.out);        
    System.out.println();




    return soapMessage;
}

}

This is the output that i get on console

Request SOAP Message:<SOAP-ENV:Envelope xmlns:SOAP- ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:example="http://ws.cdyne.com/"><SOAP-ENV:Header/><SOAP-ENV:Body><example:VerifyEmail><example:email>mutantninja@gmail.com</example:email><example:LicenseKey>123</example:LicenseKey></example:VerifyEmail></SOAP-ENV:Body></SOAP-ENV:Envelope>

Answer 1

i followed the same tutorial as you did.

and faced the same problem, just if anybody else need this , i solved the problem by deleting the name space alias "example", in the inner nodes, I only left it in the first parameter node search:

 SOAPBody soapBody = envelope.getBody();
    SOAPElement soapBodyElem = soapBody.addChildElement("search", "example");  /*"example"*/

SOAPElement soapBodyElem0 = soapBodyElem.addChildElement("arg0");
SOAPElement soapBodyElem1 = soapBodyElem0.addChildElement("name");
soapBodyElem1.addTextNode("test");
SOAPElement soapBodyElem2 = soapBodyElem0.addChildElement("number");
soapBodyElem2.addTextNode("5");

MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("SOAPAction", serverURI  + "search");

as i saw in the SoapUI autogenerated XML (only in search node)

 <example:search>
         <!--Optional:-->
         <arg0>
            <!--Optional:-->
            <name>234</name>
            <number>5</number>
         </arg0>
      </example:search>

This solved my problem.

toString() for Node is implemented as ["+getNodeName()+": "+getNodeValue()+"], and getNodeValue() will be null for element nodes. Therefore, you'll get [soap:Body: null].

However, the body is there, and you can work with it as you normally would.

Try the following to see that all of the elements are there:

SOAPBody body = soapResponse.getSOAPBody();
System.out.println(body.getElementsByTagName("ResponseText").item(0).getTextContent());
System.out.println(body.getElementsByTagName("ResponseCode").item(0).getTextContent());
System.out.println(body.getElementsByTagName("GoodEmail").item(0).getTextContent());
