JAXB Complex子XmlRootElement

Question

i need the below format output using JAXB

<?xml version="1.0" encoding="UTF-8"?>
<tata-sky>
    <change-package-request>
        <sub-no>1064781105</sub-no>
        <ivr-id>ubona_7301341344310891411101430133</ivr-id>
        <date-time>05/29/2013 00:16:13</date-time>
        <package-list>
            <package-ref>Punjabi Regional Free Pack</package-ref>
            <action-code>Delete</action-code>
        </package-list>
    </change-package-request>
</tata-sky>

The output Iam getting

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tata-sky>
    <change-package-request>
        <sub-no>1064781105</sub-no>
        <ivr-id>ubona_7301341344310891411101430133</ivr-id>
        <date-time>05/29/2013 00:16:13</date-time>
    </change-package-request>
    <package-ref>
        <package-ref>Punjabi Regional Free Pack</package-ref>
        <action-code>Delete</action-code>
    </package-ref>
</tata-sky>

('package-ref' should be child of 'change-package-request'.Below is my Code)

ChangePackage .java

package com.tsg.flow;

/**

import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(name = "tata-sky")
public class ChangePackage {

    //@XmlElement(name = "change-package-request", required = true)
    private ChangepackageRequest changePReq;


    public void setChangePReq(ChangepackageRequest changePReq) {
        this.changePReq = changePReq;
    }
  @XmlElement(name = "change-package-request")
    public ChangepackageRequest getChangePReq() {
        return changePReq;
    }
 private PackageRef packageList;


    public void setPackageList(PackageRef packageList) {
        this.packageList = packageList;
    }
@XmlElement(name = "package-ref")
    public PackageRef getPackageList() {
        return packageList;
    }

    public ChangePackage() {
    }
}

     }*/
    //@XmlElementWrapper(name = "change-package-request")    
    @XmlElement(name = "sub-no")
    public String getSub_no() {

Main Method: ChangePackageService.java

package com.tsg.flow;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

/** 
 *
 * @author Shafiq

public class ChangePackageService {

    public static void main(String... args) {
        // public String createXMLString() {
        ChangePackage objCP = new ChangePackage();
        ChangepackageRequest cr = new ChangepackageRequest();

        cr.setSub_no("1064781105");
        cr.setIvr_id("ubona_7301341344310891411101430133");
        cr.setDate_time("05/29/2013 00:16:13");
        PackageRef pl = new PackageRef();
        pl.setPackage_ref("Punjabi Regional Free Pack");
        pl.setAction_code("Delete");
        objCP.setPackageList(pl);
        objCP.setChangePReq(cr);


        // create JAXB context and instantiate marshaller
        JAXBContext context = null;
        Marshaller m = null;
        try {
            context = JAXBContext.newInstance(ChangePackage.class);
            m = context.createMarshaller();
            m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            // Write to System.out
            //m.marshal(cs, System.out);
            // Write to File
            m.marshal(objCP, System.out);
        } catch (JAXBException ex) {
            System.out.println("Error XML Generation" + ex.getMessage());
            // System.out.println("Exception Occured during marshalling: " + ex.getMessage());

        }

        //  return "";
        //  }
    }
}

Please All do reply the solution at the earliest.Thanks

Answer 1

It looks like you have commented out part of the code in ChangepackageRequest that tells JAXB that package-list is a child of change-package-request ie

@XmlElement(name = "package-ref")
public PackageList getPackageList() {`

What you would need to do is

• Uncomment that code
• Update it to use the PackageRef class instead of PackageList
• Remove any reference to PackageRef from ChangePackage

Answer 2

I found the solution...

in ChangePakageRequest.java

"added @XmlType(propOrder = {""}))"

so @XmlType(propOrder = {"", "date_time", "ivr_id", "sub_no"}) hence it assume that package-ref is a child of change-package-request.
