Create xml string for java jaxb bean with Root class & inner classes having different name spaces

Question

I have a Root Class called Employee, which has two elements empid and name and another jaxb class called Address. Below is the sample snippet.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Request",propOrder = {
    "header",
    "body",
    "signature"
})
@XmlRootElement(name="Employee")
public class Employee
    implements Serializable
{

 @XmlElement(name = "Header", required = true)
    protected String empId;
    @XmlElement(name = "Body", required = true)
    protected String empName;
    @XmlElement(name = "Address", required = true)
    protected Address address;

.. setters and getters
}


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Address", propOrder = {
    "streetLine1",
    "streetLine2",
})
@XmlRootElement(name="Address",namespace= "http://www.w3.org/2000/09/xmldsig#")
public class Employee
    implements Serializable
{

    private final static long serialVersionUID = 100L;
    @XmlElement(name = "addressLine1", required = true)
    protected String addressLine1;
    @XmlElement(name = "addressLine2", required = true)
    protected String addressLine2;

//Setters and getters

}

Now when I generate the XML string with jaxb marshalling I want the expected result like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<Employee xmlns="http://www.test.com">

   <empId>124</empId>
   <empName>name</empName>

   <Address xmlns:ns2="http://www.w3.org/2000/09/xmldsig#">
       <ns2:streetLine1 Id="line1"/>
       <ns2:streetLine2 Id="Line2"/>
   </Address>
</Request>

Please suggest. Thanks in Advance.

There are some problems with your JAXB classes, I think you have copy pasted and changed some names wrongly. The following elements inside @XMLType must be defined as @XMLElement.

@XmlType(name = "Request",propOrder = {
    "header",
    "body",
    "signature"
})

Anyways assuming the classes are right. You will need 2 changes to generate XML that has elements referred in different namespace.

Move the namespace to package level using @XMLSchema. i.e Add package-info.java at the package level to specify the namespaces.
Provide Address element with its own namespace in Employee class. Each element if not in parent namespace, must be overridden at this level.

package-info.java

@XmlSchema(
        namespace = "http://www.test.com",
        elementFormDefault = XmlNsForm.QUALIFIED)
package int1.d;

import javax.xml.bind.annotation.*;

Employee.java

package int1.d;

import java.io.Serializable;

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

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Request",propOrder = {
        "header",
        "body",
        "signature"
    })
@XmlRootElement(name="Employee")
public class Employee
    implements Serializable
{

    private static final long serialVersionUID = 8293193254658211943L;

    @XmlElement(name = "Header", required = true)
    protected String empId;
    @XmlElement(name = "Body", required = true)
    protected String empName;
    @XmlElement(name = "Address", namespace="http://www.w3.org/2000/09/xmldsig#", required = true )
    protected Address address;
    public String getEmpId() {
        return empId;
    }
    public void setEmpId(String empId) {
        this.empId = empId;
    }
    public String getEmpName() {
        return empName;
    }
    public void setEmpName(String empName) {
        this.empName = empName;
    }
    public Address getAddress() {
        return address;
    }
    public void setAddress(Address address) {
        this.address = address;
    }
}

package-info.java

@XmlSchema(
        namespace = "http://www.w3.org/2000/09/xmldsig#",
        elementFormDefault=XmlNsForm.QUALIFIED )    
package int1.d2;

import javax.xml.bind.annotation.*;

Address.java

package int1.d2;

import java.io.Serializable;

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

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Address", propOrder = {
        "streetLine1",
        "streetLine2",
    })
@XmlRootElement(name="Address")
public class Address
    implements Serializable
{

    private final static long serialVersionUID = 100L;
    @XmlElement(name = "addressLine1", required = true)
    protected String addressLine1;
    @XmlElement(name = "addressLine2", required = true)
    protected String addressLine2;

    public String getAddressLine1() {
        return addressLine1;
    }
    public void setAddressLine1(String addressLine1) {
        this.addressLine1 = addressLine1;
    }
    public String getAddressLine2() {
        return addressLine2;
    }
    public void setAddressLine2(String addressLine2) {
        this.addressLine2 = addressLine2;
    }


}

output generated by JAXB

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Employee xmlns="http://www.test.com" xmlns:ns2="http://www.w3.org/2000/09/xmldsig#">
    <Header>124</Header>
    <Body>bae</Body>
    <ns2:Address>
        <ns2:addressLine1>line1</ns2:addressLine1>
        <ns2:addressLine2>line2</ns2:addressLine2>
    </ns2:Address>
</Employee>
