How to convert SOAP request and response in XML format? - web-services

Question

I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get request and response in XML format from a SOAP request and response. Here's a sample of the code I've got right now, and where I'm trying to grab the XML:
package com.ewb.socialbanking.creditcardMain;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.ws.soap.client.core.SoapActionCallback;
import com.ewb.socialbanking.creditcardws.GetCcNumber;
import com.ewb.socialbanking.creditcardws.GetCcNumberResponse;
import com.safenet.wsdl.LoginUser;
/*THIS IS HOW I AM GIVING THE REQUEST :
AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
ctx.register(CreditCardConfig.class);
ctx.refresh();
CreditCardClient cCClient = ctx.getBean(CreditCardClient.class);
GetCcNumber cCNumber = new GetCcNumber();
ObjectFactory enrollObjFactory = new ObjectFactory();
cCNumber.setT24Cif(enrollObjFactory.createString("abc"));
cCNumber.setLinkId(enrollObjFactory.createString("def"));
cCNumber.setCcCif(enrollObjFactory.createString("ghi"));
cCNumber.setMsgRefNo(enrollObjFactory.createString("jkl"));
GetCcNumberResponse valueForRes = cCClient.getCreditCardDetails(cCNumber);*/
public class CreditCardClient extends WebServiceGatewaySupport {
public GetCcNumberResponse getCreditCardDetails(GetCcNumber request) {
//I want here request in xml format??
System.out.println("req : "+request);
//Right now it is coming as :
//req : com.ewb.socialbanking.creditcardws.GetCcNumber#5d534f5d
GetCcNumberResponse response = null;
try {
response = (GetCcNumberResponse) getWebServiceTemplate()
.marshalSendAndReceive(
request,
new SoapActionCallback(
"http://F9M9MV1RENTAL:8088/mocksoap/GetCcNumber"));
} catch (Exception e) {
e.printStackTrace();
}
//I want here response in xml format??
System.out.println("res : "+response);
//Right now it is coming as :
//res : com.ewb.socialbanking.creditcardws.GetCcNumberResponse#514646ef
return response;
}
}

Answer 1

JAX-WS services return JAXB objects. If you want to marshall that object to an outputstream, you simply use the JAXB API.
Marshaller m = JAXBContext.newInstance(GetCcNumberResponse.class).createMarshaller();
m.marshal(response, System.out);

I've tried by my self, and it works. If you want to get the SOAP message, a good way to do it is using a handler at server side. The following is my handler.
package com.documentType.handler;
import java.io.IOException;
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPException;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class TestHandler implements SOAPHandler<SOAPMessageContext> {
#Override
public void close(MessageContext arg0) {
// TODO Auto-generated method stub
}
#Override
public boolean handleFault(SOAPMessageContext arg0) {
// TODO Auto-generated method stub
return false;
}
// this method will be called twice (in and out)
#Override
public boolean handleMessage(SOAPMessageContext context) {
// true if the msg is going out
Boolean outBoundMsg = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
try {
if (outBoundMsg) {
System.out.println("this is response");
context.getMessage().writeTo(System.out);
} else {
System.out.println("this is request");
context.getMessage().writeTo(System.out);
}
} catch (SOAPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return true;
}
#Override
public Set<QName> getHeaders() {
// TODO Auto-generated method stub
return null;
}
}
The output in console is as the following
this is request
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Header/><S:Body><ns2:echo xmlns:ns2="http://ws.documentType.com/"><arg0>yoyoyo</arg0></ns2:echo></S:Body></S:Envelope>
this is response
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:echoResponse xmlns:ns2="http://ws.documentType.com/"><return>echo: yoyoyo</return></ns2:echoResponse></S:Body></S:Envelope>
If you have difficulty to add a handler, follow the following tutorial
