Parsed SOAP response is different with the received response

问题


I am trying to parse a SOAP response. I can show the full response using following line. 

  System.out.println("Response: " + out.toString());

However when I parse the response and marshall the parsed response, it shows a wrong response.

package-info.java

@XmlSchema( 
    namespace = "http://v3.hotel.wsapi.ean.com/",
    elementFormDefault = XmlNsForm.QUALIFIED) 
package com.ean;

import javax.xml.bind.annotation.XmlNsForm;

How to Fix Things

Unmarshal at the Right Level

Currently you are unmarshalling the XML node that corresponds to the soap:Body element, instead you need to navigate down to the HotelListResponse element and unmarshal that.

You could try the following:

DOMSource source = new DOMSource(sb.getFirstChild().getFirstChild());

Watch your Namespace Qualification

In the XML that you have marshalled all the elements appear qualified with the http://v3.hotel.wsapi.ean.com/, the document that you are trying to unmarshal doesn't have this namespace qualification so you should remove the @XmlSchema annotation from the package-info class.

Use Unmarshaller instead of JAXB.unmarshal

Instead of doing the following:

results = (HotelListResponse) JAXB.unmarshal(source, HotelListResponse.class);

I would recommend doing:

JAXBContext jc = JAXBContext.newInstance(HotelListResponse.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
results = unmarshaller.unmarshal(source, HotelListResponse.class).getValue();

What is Happening Now

When you use an unmarshal method that takes a class parameter, you are telling JAXB what class that XML corresponds to instead of having it automatically determined by the root element.

results = (HotelListResponse) JAXB.unmarshal(source, HotelListResponse.class)

Because the level of the XML document is wrong JAXB isn't able to match any of it to your domain model. Therefore only the default values are populated. This is why the result is full of values that are 0 or false.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<HotelListResponse xmlns="http://v3.hotel.wsapi.ean.com/">
    <numberOfRoomsRequested>0</numberOfRoomsRequested>
    <moreResultsAvailable>false</moreResultsAvailable>
    <HotelList size="0" activePropertyCount="0"/>
</HotelListResponse>
