I have a Web Service in JAX-WS and the maven goal('ws-jwsc') in pom.xml generates the WSDL file along with the input and output XSD.
I want to change the mapping of java class' attributes to WSDL/XSD schema in a different manner, as shown below:
I have two classes 1) Customer 2) Location
1. Customer - Customer specific info
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
public class Customer {
public Customer() {
super();
}
public Customer(CustomerType customerType) {
this.customerType = customerType;
}
public enum CustomerType {
B, S, C
}
private CustomerType customerType;
private String name;
private Long accountNumber;
private Location location;
// getter/setter for properties
}
2. Location - Location object to contain addr1/addr2/city/state/zip/country
#XmlRootElement
#XmlAccessorType(XmlAccessType.FIELD)
public class Location {
private String address1;
private String address2;
private String city;
private String state;
private String zip;
private String country;
/**
* #return the city
*/`enter code here`
public String getCity() {
return city;
}
//getter/setter for properties
}
Now My question is at runtime there can be 3 values('B','C','S') of 'customerType' attribute in Customer class
So,
For example if the runTime value of customerType is 'S'.
then the code shall generate the Location object properties as 'ShipperAddress1', 'ShipperAddress2', 'ShipperCity', 'ShipperState', 'ShipperZip', 'ShipperCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country'properties respectively in the SOAP response XML.
example2: if the runTime value of customerType is 'C'.
then the code shall generate the Location object properties as 'ConsigneeAddress1', 'ConsigneeAddress2', 'ConsigneeCity', 'ConsigneeState', 'ConsigneeZip', 'ConsigneeCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country' properties respectively in the SOAP response XML.
I need to know whether it is possible to do that, If yes then How?
All the help is greatly appreciated.
You can very well do it, usning #XmlElementRef and then using "inheritence of Location.
Have a base class for Location, or AbstractLocation, and then "create" instance of Location for Customer Type shipper or consignee and Override the element name in child classes. I have an example below to demonstrate where I am showing it for one field Address1. You can overrride all required fields similarly.
Note that instead of having a Field Access type, I have made it Property so that we override only methods and fields remain "private" in base class. You can adapt that also, if you think field can be protected..
Example
In example I have just used LocationC and LocationS. You can add LocationB.

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() {
}
}
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:

Also, inside the same "test" package the jaxb.index file with:
DataPacket
ConsumerProfile
ConsumerDetails
IdDetails
Then, when testing with this Test class:
package test;
import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
public class Test {
public static void main(String[] args) {
try{
JAXBContext jc = JAXBContext.newInstance(DataPacket.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("input2.xml");
DataPacket dp = (DataPacket) unmarshaller.unmarshal(xml);
Body body = dp.getBODY();
ConsumerProfile profile = body.getProfile();
ConsumerDetails consumerDetail = profile.getCONSUMER_DETAILS2();
IdDetails idDetails = profile.getID_DETAILS2();
System.out.println("ConsumerDetails name:"+consumerDetail.getNAME()+
" date of birth:"+consumerDetail.getDATE_OF_BIRTH()+
" gender:"+consumerDetail.getGENDER()+
"IdDetails SLNO:"+idDetails.getSLNO()+
" SOURCE_ID:"+idDetails.getSOURCE_ID()+
" ID_VALUE:"+idDetails.getID_VALUE()+
" EXP_DATE:"+idDetails.getEXP_DATE());
}
catch(JAXBException e){
System.out.println(e.getMessage());
e.printStackTrace();
}
}
}
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.
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.
Made changes in xml structure
