JAXB map to object insteadof string - java

I have the following XML:
<game name="m1itskow" sourcefile="maygay1bsw.c" ismechanical="yes" cloneof="m1itsko" romof="m1itsko">
<description>It's A Knockout (Maygay) (M1A/B) (set 24)</description>
<year>199?</year>
<manufacturer>Maygay</manufacturer>
</game>
Today I have manufacturer as a String inside Game class, but I need to map to a Manufacturer class, how should I do it? Is it possible? thanks.
edit: The XML cannot be changed because this is a generated file by a 3rd party tool.

Get elements as list

I have this JAXB component which I would like to get as a list:
#XmlRootElement(name = "payment")
#XmlAccessorType(XmlAccessType.FIELD)
public class Transaction {
#XmlElement(name = "transaction_types")
public TransactionTypes transactionTypes;
}
public class TransactionTypes {
#XmlElement(name = "transaction_type")
public String transaction_type;
#XmlAttribute
public String name;
public String getTransaction_type() {
return transaction_type;
}
public void setTransaction_type(String transaction_type) {
this.transaction_type = transaction_type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
XML structure:
<payment>
<transaction_types>
<transaction_type name="type1"/>
<transaction_type name="type2"/>
<transaction_type name="type3"/>
</transaction_types>
</payment>
The question is how I can get all transaction types as a list?
Can you give me some idea how should I modify the JAXB Object?
EDIT:
I tried this
#XmlRootElement(name = "payment")
#XmlAccessorType(XmlAccessType.FIELD)
public class Transaction {
#XmlElementWrapper(name = "transaction_types")
public List<TransactionTypes> transactionTypes;
}
Inner object which will hold the list:
public class TransactionTypes {
#XmlElement(name = "transaction_type")
public String transaction_type;
#XmlAttribute
public String name;
public String getTransaction_type() {
return transaction_type;
}
public void setTransaction_type(String transaction_type) {
this.transaction_type = transaction_type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

To get all the transaction_type as a list, I have somewhat modified your code. I have introduced a new class TransactionList which will contain the list of transaction_type
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement(name = "payment")
#XmlAccessorType(XmlAccessType.FIELD)
public class Transaction {
#XmlElement(name = "transaction_types")
public TransactionList transactionList;
public Transaction() {
super();
}
#Override
public String toString() {
return "Transaction [TransactionList=" + transactionList + "]";
}
}
TransactionList class
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
#XmlAccessorType(XmlAccessType.FIELD)
public class TransactionList {
#XmlElement(name = "transaction_type")
public List<TransactionType> transactionType;
public TransactionList(List<TransactionType> transactionTypes) {
transactionType = transactionTypes;
}
public TransactionList() {
super();
}
#Override
public String toString() {
StringBuilder sb = new StringBuilder();
for (TransactionType transactionType : transactionType) {
sb.append(transactionType + "\n");
}
return sb.toString();
}
}
TransactionType class
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
#XmlAccessorType(XmlAccessType.FIELD)
public class TransactionType {
#XmlElement(name = "transaction_type")
private String transaction_type;
#XmlAttribute
private String name;
public TransactionType(String transaction_type, String name) {
this.transaction_type = transaction_type;
this.name = name;
}
public TransactionType() {
}
public String getTransaction_type() {
return transaction_type;
}
public void setTransaction_type(String transaction_type) {
this.transaction_type = transaction_type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Override
public String toString() {
return "TransactionTypes [transaction_type=" + transaction_type + ", name=" + name + "]";
}
}
main method
public static void main(String[] args) throws Exception {
JAXBContext context = JAXBContext.newInstance(Transaction.class);
Unmarshaller um = context.createUnmarshaller();
Transaction transaction = (Transaction) um.unmarshal(new FileReader(FILE));
System.out.println(transaction);
}
You can also check the output by directly changing the variable transactionType to List in Transaction table and assigning XMLElementWrapper annotation to it
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement(name = "payment")
#XmlAccessorType(XmlAccessType.FIELD)
public class Transaction {
#XmlElementWrapper(name = "transaction_types")
public List<TransactionType> transactionType;
public Transaction() {
}
}

Not able to extract only selected Tag values using Jaxb in Java

I've a very big XML string. Im posting here only part of the XML object. I'm trying to convert this XML to Java object. My first question is, should I need to create Java object of total XML tag values or can I have create the Java object of only selected inner XML objects? Please find my XML string.

P.S
I've used DocumentBuilder and I'm able to fetch the values using it. But, I want to extract using Jaxb.

You can't annotate as #XmlRootElement the Java class mirroring the XML element that you're interested on. You have to mirror in Java all the XML elements from the topmost element in the XML file (DATAPACKET) to the lowest ones (CONSUMER_DETAILS2 and ID_DETAILS2) in the path that you're interested, even if you're only interested in some of them.
I assume that the operator isn't interested in RUID (because the class CONSUMER_DETAILS2 doesn't include a field for this XML element), and also that the field NATIONALITY is not going to be loaded from this XML.
If the input XML of the question were in a file named input2.xml, then I'd have the following Java classes:

Unable to get attribute value using JAXB ( For attribute in Parent class)

I am trying to read one xml using JAXB.
I am facing one weird issue where attribute of parent is not being read,but attributes of child classes are read.
I have referenced forums, but this seems to be a strange one.
Can anyone please let me know what is the mistake i am doing.

As you can see the exchangeName is null despite mentioning XMLAttribute annotation for field.
Thanks,

You've declared the exchangeName attribute in the PhoneDirectory class but your XML has this attribute in the Exchange element.
So instead of
private String exchange;
private String exchangeName;
you'll need a class like Exchange with #XmlAttribute exchangeName and #XmlValue exchange.

Reading XML files from java

I am trying to read an XML file from java program. I am able to read its contents.I am posting the XML file from which i am reading contents.
<?xml version="1.0" encoding="UTF-8" ?>
<customer id="100">
<age>29</age>
<name>lucifer</name>
</customer>
i am able to write its contents through java program i am posting my code..
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Customer {
String name;
int age;
int id;
public String getName() {
return name;
}
#XmlElement
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
#XmlElement
public void setAge(int age) {
this.age = age;
}
public int getId() {
return id;
}
#XmlAttribute
public void setId(int id) {
this.id = id;
}
}
public class CheckClass {
public static void main(String[] args) {
try {
File file = new File("./file/NewFile.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(file);
System.out.println(customer.age);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
But i have to read values from this XML file which i can not.This is my XML file
<?xml version="1.0" encoding="UTF-8"?>
<DBConfig ID="1" Name ="" DriverName="" HostName="localhost" PortName="" DBName="" ServiceName="" User="" PassWord="" sid="">
<TableConfig ID= "1" TableName="">
</TableConfig>
</DBConfig>
When i am trying to access this xml values through java class i am getting this error..

DBConf db = (DBConf) jaxbUnmarshaller.unmarshal(file);
System.out.println(db.HostName);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
can anyone help

Note that you are annotating Attribute as Element. Fix that.
Even after that if problem occurs -
Try using - #XmlAccessorType(XmlAccessType.FIELD)
Move #XmlAttribute(name = "HostName") annotations to fields instead of accessor methods.
I am not sure if this is your problem. I faced a similar problem and this helped me. I wont guarantee that it will solve your problem but prima facie, it appears that above can fix it.

dbName, sid are Attributes, but you have annotated them #XmlElement. change all the attributes to #XmlAttribute.

Why don't you use
Xstream library
Example:
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
#XStreamAlias("Cat")
class Cat {
#XStreamAsAttribute
int age;
String name;
}
public class XStreamDemo {
public static void main(String[] args) {
XStream xstream = new XStream();
xstream.processAnnotations(Cat.class);
String xml = "<Cat age='4' ><name>Garfield</name></Cat>";
Cat cat = (Cat) xstream.fromXML(xml);
System.out.println("name -> " + cat.name);
System.out.println("age -> " + cat.age);
}
}
You need to add Xstream jar files in to classpath.

Use these classes.
