Hi I am trying to convert an xml file into Java Objects using JAXB and I am very new to java. I have created the pojo classes and added some annotations but I am not sure whether they are right? I have spent hours in google but couldn't find what is wrong.
This is my xml :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<question id="1">
<answers>
<answername>java is a programming language</answername>
<id>101</id>
<postedby>ravi</postedby>
</answers>
<answers>
<answername>java is a platform</answername>
<id>102</id>
<postedby>john</postedby>
</answers>
<questionname>What is java?</questionname>
<marks set=50>
<longAnswer set=45/>
<shortAnswer set=30/>
</marks>
</question>
Pojo classes:
#XmlRootElement(name="question")
public class Question {
private int id;
private String questionname;
private List<Answer> answers;
private List<Marks> marks;
public Question() {}
public Question(int id, String questionname, List<Answer> answers, List<Marks> marks) {
super();
this.id = id;
this.questionname = questionname;
this.answers = answers;
this.marks = marks;
}
#XmlElement(name="marks")
public List<Marks> getMarks() {
return marks;
}
public void setMarks(List<Marks> marks) {
this.marks = marks;
}
#XmlAttribute
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
#XmlElement
public String getQuestionname() {
return questionname;
}
public void setQuestionname(String questionname) {
this.questionname = questionname;
}
#XmlElement
public List<Answer> getAnswers() {
return answers;
}
public void setAnswers(List<Answer> answers) {
this.answers = answers;
}
}
public class Answer {
private int id;
private String answername;
private String postedby;
public Answer() {}
public Answer(int id, String answername, String postedby) {
super();
this.id = id;
this.answername = answername;
this.postedby = postedby;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getAnswername() {
return answername;
}
public void setAnswername(String answername) {
this.answername = answername;
}
public String getPostedby() {
return postedby;
}
public void setPostedby(String postedby) {
this.postedby = postedby;
}
}
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
public class Marks {
private LongAnswer longAnswer ;
private ShortAnswer shortAnswer;
private String set;
#XmlAttribute
public String getSet() {
return set;
}
public void setSet(String set) {
this.set = set;
}
#XmlElement(name="longAnswer")
public LongAnswer getLongAnswer() {
return longAnswer;
}
public void setLongAnswer(LongAnswer longAnswer) {
this.longAnswer = longAnswer;
}
#XmlElement(name="shortAnswer")
public ShortAnswer getShortAnswer() {
return shortAnswer;
}
public void setShortAnswer(ShortAnswer shortAnswer) {
this.shortAnswer = shortAnswer;
}
}
public class LongAnswer {
private String set;
public String getSet() {
return set;
}
public void setSet(String set) {
this.set = set;
}
public class ShortAnswer {
private String set;
public String getSet() {
return set;
}
public void setSet(String set) {
this.set = set;
}
}
Can anyone tell me how to annotate the 'marks' model class and how to set 'longAnswer' and 'shortAnswer' field. Because i am getting null values for them.
You should annotate your set properties with #XmlAttribute. Otherwise it looks quite fine.
What you could also do is create an XML Schema for you XML and compile it.
I have a problem with jaxB. There is no exception and here is my xml ;

and my test method ;
private static void unmarshall() {

PinnacleLineFeed pinnacleLineFeed = (PinnacleLineFeed) unmarshaller.unmarshal(url);
System.out.println("bakıcez");
} catch (Exception ex) {
ex.printStackTrace();
}
}
When i try to unmarshall this xml, all fields are null. And there is no exception. Can anyone help ?
I have the code and xml and xml and cannot read the xml and believe that it is for the attribute. how can I read the attribute?
This is the code:
#XmlRootElement(name = "reimpresiones")
public class RePrint {
private Integer id;
private String document;
private String numberDocument;
private String extraction;
private String client;
private String groupExtraction;
private String route;
private String deliveryNote;
private String date;
private List<RePrint> reprintList;
public RePrint() {
}
#XmlAttribute(name = "id")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
#XmlElement(name = "client")
public String getClient() {
return client;
}
public void setClient(String client) {
this.client = client;
}
#XmlElement(name = "document")
public String getDocument() {
return document;
}
public void setDocument(String document) {
this.document = document;
}
#XmlElement(name = "numberDocument")
public String getNumberDocument() {
return numberDocument;
}
public void setNumberDocument(String numberDocument) {
this.numberDocument = numberDocument;
}
#XmlElement(name = "extraction")
public String getExtraction() {
return extraction;
}
public void setExtraction(String extraction) {
this.extraction = extraction;
}
#XmlElement(name = "groupExtraction")
public String getGroupExtraction() {
return groupExtraction;
}
public void setGroupExtraction(String groupExtraction) {
this.groupExtraction = groupExtraction;
}
#XmlElement(name = "route")
public String getRoute() {
return route;
}
public void setRoute(String route) {
this.route = route;
}
#XmlElement(name = "deliveryNote")
public String getDeliveryNote() {
return deliveryNote;
}
public void setDeliveryNote(String deliveryNote) {
this.deliveryNote = deliveryNote;
}
#XmlElement(name = "date")
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
#XmlElement(name = "reimprension")
public List<RePrint> getReprintList() {
return reprintList;
}
public void setReprintList(List<RePrint> reprintList) {
this.reprintList = reprintList;
}
}
This is the xml where there is a list of elements. I want to read "id" but i cannot.

Thank you
I'm new to JSF, and stuck in a problem.
I have a selectOneMenu for displaying the list of countries. When the user selects one of the country, there's another selectOneMenu having the cities (=regions in my case) should be auto-populated.
I tried several iterations for doing the same but didn't help.
Please let me know if anything else is also needed to help me. Would really appreciate it.
UPDATE:
Here's the code after adding listener:
<p:outputLabel for="countryRegistration">#{msg['country']}:</p:outputLabel>
<p:selectOneMenu id="countryRegistration" value="#{mbcActor.geoData.country}" style="width:120px;" >
<f:attribute name="country" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCountry']}" itemValue=""/>
<f:selectItems value="#{geoLists.countryList}" var="country" itemLabel="#{country.name}"/>
<p:ajax listener="#{mbcActor.geoData.updateRegions}" render="cityRegistration"/>
</p:selectOneMenu>
<p:message for="countryRegistration"/>
<p:outputLabel for="cityRegistration">#{msg['city']}:</p:outputLabel>
<p:selectOneMenu id="cityRegistration" value="#{mbcActor.geoData.region}" style="width:120px;">
<f:attribute name="regions" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCity']}" itemValue=""/>
<!--<f:selectItems value="#{geoLists.regionForCountry}" var="region" itemLabel="#{region.name}"/>-->
<f:selectItems value="#{geoLists.getRegionForCountry(country)}" var="region" itemLabel="#{region.description}"/>
</p:selectOneMenu>
<p:message for="cityRegistration"/>
But it says:
Oct 05, 2013 2:04:53 AM com.sun.faces.lifecycle.InvokeApplicationPhase execute

Your <p:ajax> tag uses the render attribute, which isn't predefined. The attribute you want is update.
supposing that registrationHelper.newActor is an instance of of a Managed Bean, I think it's probably not initialized. Why don't you make sure it is, by creating it on RegistrationHelper's PostConstruct, or even get it through a method like
public AbstractActor createNewActor() {
newActor = new AbstractActor();
return newActor;
}
<ui:param name="mbcActor" value="#{registrationHelper.createNewActor}"/>
Perhaps someone here can give me a tip where the error could be situated (JSF 2.2, Glassfish 4.0):
I have two entities with a manytomany relation (see example)
When I deploy my project in glassfish all tables (also the linking table) are generated correctly (create-tables enabled in persistence.xml): TAGUSERWISH, TAGUSERWISH_WISH (linking table), WISH
When I execute a persist (see example) entity "wish" and "tagUserWish" is persisted correctly, but nothing is written into the linking table when I look directly into the mysql table. But when I read "wish" out with JPA, the List<TagUserWish> is filled
As soon as a new session starts (redeploy) List<TagUserWish> is also empty when read out with JPA
Owner entity:
#Entity
public class Wish implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String subject;
private String abstractT;
#OneToOne

#ManyToMany(mappedBy = "wishes", cascade = {CascadeType.ALL} )
private List<TagUserWish> tags = new LinkedList<>();
public void addTag(TagUserWish tag){

return false;
}
return true;
}
#Override

}

How I persist it:
#javax.inject.Named
#SessionScoped
public class WishPM implements Serializable {
#EJB
private WishService wls;
public void commitEditWish(){
List<TagUserWish> selTags = new ArrayList<>();
selTags.add(new TagUserWish("Tag1"));
selTags.add(new TagUserWish("Tag2"));
currentWish = new Wish();
currentWish.setSubject("wishSubject");
currentWish.setAbstractT("wishAbstract");
currentWish.setTags(selTags);
wls.createWish(currentWish);
}
}
And the wish Service:
#Stateless
public class WishService implements Serializable{
#PersistenceContext(unitName = "WishlistPU")
private EntityManager em;
public void createWish(Wish entity){
em.persist(entity);
}
}
Relationships are persisted based to the owner side of relationship. Owner of the bidirectional relationship is one that is value of mappedBy in inverse side. In following case owner of the relationship is wishes field in TagUserWish entity
#ManyToMany(mappedBy = "wishes", cascade = {CascadeType.ALL} )
private List<TagUserWish> tags = new LinkedList<>();
Because instance of TagUserWish do have empty wishes collection, relationship is not persisted. Problem can be solved by adding related Wish to the instance of TagUserWish, for example as follows:
...
TagUserWish tuw1 = new TagUserWish("Tag1")
TagUserWish tuw2 = new TagUserWish("Tag2")
selTags.add(tuw1);
selTags.add(tuw2);
currentWish = new Wish();
tuw1.addWish(currentWish); //setting to owner side of relationship
tuw2.addWish(currentWish); //setting to owner side of relationship
...
