Can not unmarshall a (XML with namespace) inputstream into object - java

When I send a request to web service the following response will be received. I am using the following code to unmarshall the response XML to an object, but it seems nothing will be put into the object.

Since your XML document is namespace qualified you will need to use the package level #XmlSchema annotation to map the namespace qualification.
#XmlSchema(
namespace = "example.com",
elementFormDefault = XmlNsForm.QUALIFIED)
package example;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

How to generate one objects from two similar xml documents with jaxb

I'm trying to integrate with some provider REST API within xml. I have two requests and two very similar responses: Operation response and Check response.
Operation:
<Response>
<ReturnCode>0</ReturnCode>
<ReturnMessage>OK</ReturnMessage>
<Commands>
<OperationResponseCommand>
<ResultCode>412</ResultCode>
<ResultMessage>Some message hear</ResultMessage>
<OperationId>125206188472552900</OperationId>
<Id>14507921</Id>
</OperationResponseCommand>
</Commands>
</Response>
Check:
<Response>
<ReturnCode>0</ReturnCode>
<ReturnMessage>OK</ReturnMessage>
<Commands>
<CheckResponseCommand>
<ResultCode>412</ResultCode>
<ResultMessage>Some message hear</ResultMessage>
<OperationId>125206188472552900</OperationId>
</CheckResponseCommand>
</Commands>
</Response>
As you can see, the differences are:
<OperationResponseCommand> instead of <CheckResponseCommand>
in first xml.
One additional tag <Id> inside
<OperationResponseCommand>.
And I have two classes for Response and for Command.
First:
#Data
#XmlRootElement(name = "Response")
#XmlAccessorType(XmlAccessType.FIELD)
public class Response {
#XmlElement(name = "ReturnCode")
private Integer returnCode;
#XmlElement(name = "ReturnMessage")
private String returnMessage;
#XmlElementWrapper(name = "Commands")
#XmlElement(name = "OperationResponseCommand")
private List<Command> commands = new ArrayList<>();
}
Second:
#Data
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
public class Command {
#XmlElement(name = "ResultCode")
private Integer resultCode;
#XmlElement(name = "ResultMessage")
private String resultMessage;
#XmlElement(name = "OperationId")
private String operationId;
#XmlElement(name = "Id")
private Integer id;
}
For building response object from xml I'm using this class:
public class JAXBOperations {
public <T> T buildObjectFromXml(Class<T> clazz, String xml) {
try {
StringReader reader = new StringReader(xml);
Unmarshaller unmarshaller = createUnmarshaller(clazz);
return (T) unmarshaller.unmarshal(reader);
} catch (JAXBException e) {
throw new RuntimeException("Exception has been occurred while creating unmarshaller to parse xml to object");
}
}
public <T> String buildXmlFromObject(T objectToXml) {
try {
StringWriter writer = new StringWriter();
Marshaller marshaller = createMarshaller(objectToXml.getClass());
marshaller.marshal(objectToXml, writer);
return writer.toString();
} catch (JAXBException e) {
throw new RuntimeException("Exception has been occurred while creating marshaller to parse object to xml");
}
}
private <T> Marshaller createMarshaller(Class<T> clazz) throws JAXBException {
JAXBContext jaxbContext = JAXBContext.newInstance(clazz);
return jaxbContext.createMarshaller();
}
private <T> Unmarshaller createUnmarshaller(Class<T> clazz) throws JAXBException {
JAXBContext jaxbContext = JAXBContext.newInstance(clazz);
return jaxbContext.createUnmarshaller();
}
}
Method buildObjectFromXml. And it works fine for first xml response. I have an object like this:
Response(
returnCode=0, returnMessage=OK,
commands=[Command(
resultCode=417,
resultMessage=Processing,
operationId=b6619f26-8583-4272-b89d-d1b200109d06,
id=157427079)])
But for the second xml response it doesn't works. I have:
Response(
returnCode=0,
returnMessage=OK,
commands=[])
I tried to change the code of my Response class. Like this:
#Data
#XmlRootElement(name = "Response")
#XmlAccessorType(XmlAccessType.FIELD)
public class tResponse {
#XmlElement(name = "ReturnCode")
private Integer returnCode;
#XmlElement(name = "ReturnMessage")
private String returnMessage;
#XmlElementWrapper(name = "Commands")
#XmlElementRefs({
#XmlElementRef(name = "OperationResponseCommand", type = Command.class),
#XmlElementRef(name = "CheckResponseCommand", type = Command.class)})
private List<Command> commands = new ArrayList<>();
}
Or this:
#Data
#XmlRootElement(name = "Response")
#XmlAccessorType(XmlAccessType.FIELD)
public class Response {
#XmlElement(name = "ReturnCode")
private Integer returnCode;
#XmlElement(name = "ReturnMessage")
private String returnMessage;
#XmlElementWrapper(name = "Commands")
#XmlElement(name = "OperationResponseCommand")
private List<Command> operstionCommands = new ArrayList<>();
#XmlElementWrapper(name = "Commands")
#XmlElement(name = "CheckResponseCommand")
private List<Command> checkCommands = new ArrayList<>()
}
But it both doesn't works too.
My question is: what I'm doing wrong? How can I change code of my two classes to correct converting to object both types of xml responses?

For representing the XML elements <OperationResponseCommand>
and <CheckResponseCommand> you will need separate classes
which should be subclasses of your Command classes.
Let's call them OperationResponseCommand and CheckResponseCommand.
The properties common to all commands should remain in your
Command class. It is also a good idea to declare this class as abstract.
#Data
#XmlAccessorType(XmlAccessType.FIELD)
public abstract class Command {
#XmlElement(name = "ResultCode")
private Integer resultCode;
#XmlElement(name = "ResultMessage")
private String resultMessage;
#XmlElement(name = "OperationId")
private Integer operationId;
}
The properties specific for the commands should go into the subclasses:
#Data
#XmlAccessorType(XmlAccessType.FIELD)
public class OperationResponseCommand extends Command {
#XmlElement(name = "Id")
private Integer id;
}
#Data
#XmlAccessorType(XmlAccessType.FIELD)
public class CheckResponseCommand extends Command {
}
Finally, in your Response class you need to enhance the annotations
of your List<Command> commands property, so that JAXB
will know which object class needs to be instantiated depending
on the XML element name of the commands.
(See also the javadoc of #XmlElements.)
#XmlElementWrapper(name = "Commands")
#XmlElements({
#XmlElement(name = "OperationResponseCommand", type = OperationResponseCommand.class),
#XmlElement(name = "CheckResponseCommand", type = CheckResponseCommand.class)
})
private List<Command> commands = new ArrayList<>();

SimpleXMLConverter parse xml nodes

I'm stuck. How to parse Node with same name child node?
In this example i need nodes with rate attribute.
<xml>
<Rates>
<Rates winrate_cap="9999">
<Rates rate="323"/>
<Rates rate="343"/>
<Rates rate="2338"/>
<Rates rate="233"/>
</Rates>
</Rates>
</xml>
My response wrapper class:
#Root(name = "xml", strict = false)
public class XMLResponse {
#ElementList(entry = "Rates")
public List<Rates> response;
public static class Rates {
#Attribute(name = "winrate_cap", required = false)
public String winrate_cup;
#ElementList(required = false, entry = "Rates")
public List<Rates> rates;
}
public static class Rates {
#Attribute(name = "rate", required = false)
public String rate;
}
}

You are on the right way. As you have many Rates here, better name the class more with more context and set the xml name via Annotation.
I've separated the XMLResponse and Rates classes, but this doesn't make any difference.
The class XMLRespone maps the <xml>...</xml> part:
#Root(name = "xml")
public class XMLRespone
{
#Element(name = "Rates")
private Rates rates;
// ...
}
All types for <Rates...>...</Rates> is done by Rates class (and it's inner classes, which map the structure:
#Root(name = "Rates")
public class Rates
{
#Element(name = "Rates")
private RateList rates;
// ...
public static class RateList
{
#ElementList(entry = "Rates", inline = true)
private ArrayList<RateValue> values;
#Attribute(name = "winrate_cap", required = true)
private int winrateCap;
// ...
}
public static class RateValue
{
#Attribute(name = "rate", required = true)
private int rate;
// ...
}
}
Deserializing your XML gives this output (using generated toString()):
XMLRespone{rates=Rates{rates=RateList{values=[RateValue{rate=323}, RateValue{rate=343}, RateValue{rate=2338}, RateValue{rate=233}], winrateCap=9999}}}

Cannot parse response with JAXB

I am trying to send a REST request and parse the response, but it returns NullPointerException. I assume the issue is with namespace.
When I have package-info.java file, it returns NullPointerException and when I do not it returns following:
Exception in thread "main"
org.springframework.http.converter.HttpMessageNotReadableException:
Could not unmarshal to [class com.expedia.HotelListResponse]: unexpected

Your schema declares elementFormDefault="qualified" as we can see in your package-info, so you must remove the ns2 prefix at the root Element, or you must add it to all the inner elements, depends on the xmlns declaration (that we can't see).

Correct way to parse XML using Simple Framework

I'm using Simple framework to deserialize an xml on my android app .
The issue is on a portion of the xml because I can get the objects of the other portions of it .
Here is the part of the xml that I struggle with :

Here is my XmlMapper class :
#Root(name="webtv", strict = false)
public class XmlModelMapper {
public ConfigObject getConfigObjects() {
return configObject;
}
#Element(name="config")
public ConfigObject configObject = new ConfigObject();
#ElementList(name = "itemList")
private List<Videos> itemList = new ArrayList<Videos>();
public List<Videos> getItemList() {
return itemList;
}
#ElementList(name = "chaineList")
private List<Chaine> chaineList = new ArrayList<Chaine>();
public List<Chaine> getChaineList() {
return chaineList;
}
}
If I change my mapper class to this :
#Root(name="webtv", strict = false)
public class XmlModelMapper {
public List<ConfigObject> getConfigObjects() {
return configObject;
}
//change is here using a list not an object
#ElementList(name="config")
public List<ConfigObject> configObjects = new ArrayList<ConfigObject>();
#ElementList(name = "itemList")
private List<Videos> itemList = new ArrayList<Videos>();
public List<Videos> getItemList() {
return itemList;
}
#ElementList(name = "chaineList")
private List<Chaine> chaineList = new ArrayList<Chaine>();
public List<Chaine> getChaineList() {
return chaineList;
}
}
and the log the size of the List I get 4 which is correct , but how to get each object in a distinct way including the extension (attribute)
Please help me solving this issue .
Thanks

#ElementList(name="config")
public List<ConfigObject> configObjects = new ArrayList<ConfigObject>();
This wont match with your xml listed above. While the #Element-based solution (example 1) will create a proper config-tag, the list adds another "list-tag"; here's an example:
<config> <!-- This is the list's tag, wrapping all elements -->
<config> <!-- This is the actual element's tag -->
<pathVideo extension="mp4">http://video.com</pathVideo>
<pathBigImage extension="jpg">http://bigimg.com</pathBigImage>
<pathImage extension="jpg">http://image.com</pathImage>
<pays>GB;IE</pays>
</config>
<!-- some more <config>...</config> -->
</config>
The solution: Use athe inline list - those don't have the "list-tag".
#ElementList(name = "config", inline = true, entry = "config")
public List<ConfigObject> configObjects = new ArrayList<>();
For the sake of completeness, here are my classes used for testing:
class Chaine { /* empty - enough for testing */ }
class Videos { /* empty - enough for testing */ }
#Root
public class ConfigObject
{
#Element(name = "pathVideo")
private PathConfig video;
#Element(name = "pathBigImage")
private PathConfig bigImage;
#Element(name = "pathImage")
private PathConfig image;
#Element(name = "pays")
private String pays;
// ...
}
#Root
public class PathConfig
{
#Attribute(name = "extension")
private String extension;
#Text
private String path;
// ...
}

Solved my issue and learned alot about simple framework which is great and light weight , but I prefer ollo's answer
Please discard ormlite annotations
My classes :
#Root(name="webtv", strict = false)
public class XmlModelMapper {
public ConfigObject getConfigObject() {
return configObject;
}
#Element(name="config")
public ConfigObject configObject = new ConfigObject();
//rest of the elements
...
}
and
#Root(name = "config" , strict = false)
public class ConfigObject {
#Element
PathVideo pathVideo;
#Element
PathImage pathImage;
#Element
PathBigImage pathBigImage ;
//rest of the elements
}
and
#Root(name = "pathImage")
#DatabaseTable(tableName = "imageconfig")
public class PathImage {
#DatabaseField(generatedId = true)
Integer id ;
#Attribute
#DatabaseField
String extension;
#Text
#DatabaseField
String pathImage;
//rest of the elements...
}
and
#Root(name = "pathVideo")
#DatabaseTable(tableName = "videoconfig")
public class PathVideo {
#DatabaseField(generatedId = true)
Integer id ;
#Attribute
#DatabaseField
String extension;
#Text
#DatabaseField
String pathVideo;
}
and finally
#Root(name = "pathBigImage")
#DatabaseTable(tableName = "bigimageconfig")
public class PathBigImage {
#DatabaseField(generatedId = true)
Integer id ;
#Attribute
#DatabaseField
String extension;
#Text
#DatabaseField
String pathBigImage;
//rest of the elements...

Can't unmarchall elements from XML file with JAXB

I want to convert context of xml file to java object.
But some part is extracted ok, and some has null values.
Here is xml file:
<OTA_AirLowFareSearchRQ EchoToken="50987" SequenceNmbr="1" Target="Production" TimeStamp="2003-11-19T19:44:10-05:00"
Version="2.001"
xsi:schemaLocation="http://www.opentravel.org/OTA/2003/05 OTA_AirLowFareSearchRQ.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.opentravel.org/OTA/2003/05">
<POS>
<TPA_Extensions>
<TPA_Extension>
<PromoRatesRequired Value="false"/>
<UserName Value="342561"/>
<UserPassword Value="1234"/>
<ClearCache Value="true"/>
</TPA_Extension>
</TPA_Extensions>
</POS>
<OriginDestinationInformation>
<DepartureDateTime>2015-04-13T00:00:00</DepartureDateTime>
<OriginLocation LocationCode="DUB"/>
<DestinationLocation LocationCode="CDG"/>
</OriginDestinationInformation>
<TravelPreferences>
<CabinPref PreferLevel="Preferred" Cabin="Economy"/>
</TravelPreferences>
<TravelerInfoSummary>
<AirTravelerAvail>
<PassengerTypeQuantity Code="ADT" Quantity="1"/>
<PassengerTypeQuantity Code="CHD" Quantity="0"/>
<PassengerTypeQuantity Code="INF" Quantity="1"/>
</AirTravelerAvail>
</TravelerInfoSummary>
</OTA_AirLowFareSearchRQ>
I have trouble with extracting 'OriginDestinationInformation' and 'AirTravelerAvail'.
Here is main():
public static void main(String[] args) {
try {
JAXBContext context = JAXBContext.newInstance(OTAAirLowFareSearchRQ.class);
Unmarshaller um = context.createUnmarshaller();
OTAAirLowFareSearchRQ rq = (OTAAirLowFareSearchRQ) um.unmarshal(new FileReader(FILE_NAME));
System.out.println(rq);
} catch (FileNotFoundException | JAXBException e) {
LOGGER.error(e);
}
}
Here is output snippet:
originDestinationInformation=[OriginDestinationInformation{
departureDateTime=null,
originLocation=null,
destinationLocation=null,
alternateLocationInfo=null,
rph='null',
refNumber=null}],
travelerInfoSummary=TravelerInfoSummary{
ticketingCountryCode='null',
specificPTCIndicator=null,
airTravelerAvails=null},
echoToken='50987',
timeStamp=2003-11-19T19:44:10-05:00,
target='Production',
version=2.001,
transactionIdentifier='null',
sequenceNmbr=1,
And much more interesting part OriginDestinationInformation:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "OriginDestinationInformation", propOrder = {
"departureDateTime",
"originLocation",
"destinationLocation",
"tpaExtensions",
"alternateLocationInfo",
"rph",
"refNumber"
})
public static class OriginDestinationInformation extends OriginDestinationInformationType {
#XmlElement(name = "DepartureDateTime", required = true)
protected TimeInstantType departureDateTime;
#XmlElement(name = "OriginLocation", required = true)
protected OriginLocation originLocation;
#XmlElement(name = "DestinationLocation", required = true)
protected DestinationLocation destinationLocation;
#Transient
#XmlElement(name = "AlternateLocationInfo")
protected AlternateLocationInfo alternateLocationInfo;
#XmlElement(name = "TPA_Extensions")
protected TPAExtensionsType tpaExtensions;
#XmlAttribute(name = "RPH")
protected String rph;
#XmlAttribute(name = "RefNumber")
protected Integer refNumber;
// getters and setters
TimeInstantType:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "TimeInstantType", propOrder = {
"value"
})
public class TimeInstantType {
#Property("dateTime")
#XmlValue
protected String value;
// rest of class
OriginLocation:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "OriginLocation")
public static class OriginLocation extends LocationType {
#XmlAttribute(name = "MultiAirportCityInd")
protected Boolean multiAirportCityInd;
#XmlAttribute(name = "AlternateLocationInd")
protected Boolean alternateLocationInd;
#XmlAttribute(name = "LocationCode")
protected String locationCode;
DestinationLocation:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "DestinationLocation")
public static class DestinationLocation extends LocationType {
#XmlAttribute(name = "MultiAirportCityInd")
protected Boolean multiAirportCityInd;
#XmlAttribute(name = "AlternateLocationInd")
protected Boolean alternateLocationInd;
#XmlAttribute(name = "LocationCode")
protected String locationCode;
and for list of objects TravelerInfoSummary
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "TravelerInfoSummary", propOrder = {
"airTravelerAvails",
"ticketingCountryCode",
"specificPTCIndicator"
})
public static class TravelerInfoSummary extends TravelerInfoSummaryType {
#Embedded
#XmlElement(name = "AirTravelerAvail")
protected List<AirTravelerAvail> airTravelerAvails;
AirTravelerAvail:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "AirTravelerAvail")
public class AirTravelerAvail {
#Embedded
#XmlElement(name = "PassengerTypeQuantity")
#XmlElementWrapper(name = "AirTravelerAvail")
protected List<PassengerTypeQuantity> passengerTypeQuantities;
I couldn't figure out what is wrong here. I tried
#XmlElementWrapper(name = "AirTravelerAvail")
for list of objects but it keep getting null.
How to solve this trouble?

To start off, I hate JAXB!
That said, i literally have to specify
#XmlElemnt(namespace = "namespace")
on every element of a class. JAXB simply does not assign the default namespace to the current xml dom.
By default, JAXB seems to work with ElementFormDefault="unqualified" and AttributeFormDefault="qualified" (I may have confused this), but this makes it unmarshall the root element, considering only attributes as belonging to the default-namespace.
If the namespace has a prefix e.g. xmlns:ns="namespace", then JAXB will correctly marshall elements as to belonging to this namespace.
If you have control over xml, simply have a prefix to the default namespace, like
xmlns:ns="http://www.opentravel.org/OTA/2003/05"
If you dont, make sure to have
#XmlElement(namespace = "http://www.opentravel.org/OTA/2003/05")
on every element that is not an attribute.
