I have an Marshalling problem using reference IDREFs.
Context:
I have 2 object "b" and "c" which references the same object "a",
and the object "d" which contains "b" and "c".
When i marshal the object "d", the xml data contains "d", "b" and "c"
but the referenced object "a" is missing, i don't understand why ?
My simple source code:
public class A
{
private int m_reference;
private String m_name;
public void setReference(int _reference) {
m_reference = _reference;
}
public int getReference(){
return m_reference;
}
public void setName(String _name) {
m_name = _name;
}
public String getName() {
return m_name;
}
public A() {
}
}
public class B
{
private String m_type;
private A m_a;
public void setType(String _type) {
m_type = _type;
}
public String getType() {
return m_type;
}
public void setA(A _a) {
m_a = _a;
}
public A getA() {
return m_a;
}
public B() {
}
}
public class C
{
private String m_category;
private A m_a;
public void setCategory(String _category) {
m_category = _category;
}
public String getCategory() {
return m_category;
}
public void setA(A _a) {
m_a = _a;
}
public A getA() {
return m_a;
}
public C() {
}
}
public class D
{
private int m_number;
private B m_b;
private C m_c;
public void setNumber(int _number) {
m_number = _number;
}
public int getNumber() {
return m_number;
}
public void setB(B _b) {
m_b = _b;
}
public B getB() {
return m_b;
}
public void setC(C _c) {
m_c = _c;
}
public C getC() {
return m_c;
}
public D() {
}
}
package test;
import test.server.*;
import java.io.*;
import org.exolab.castor.xml.*;
import org.exolab.castor.mapping.*;
public class OnServerSide
{
private Mapping m_mapping = XMappingLoader.Load("Mapping.xml");
private D m_d;
public OnServerSide()
{
A a = new A();
a.setReference(15);
a.setName("TOTO");
B b = new B();
b.setType("XX25");
b.setA(a);
C c = new C();
c.setCategory("C3");
c.setA(a);
m_d = new D();
m_d.setNumber(123);
m_d.setB(b);
m_d.setC(c);
}
public void marshall()
{
byte[] xmlData = null;
try
{
// Create a byte array output stream.
ByteArrayOutputStream baos = new ByteArrayOutputStream();
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(baos);
// Create a new castor marshaller.
Marshaller marshaller = new Marshaller(outputStreamWriter);
// Note the resolver must be set before the mapping, otherwise
// the mapping will be ignored.
if (m_mapping != null)
{
marshaller.setMapping(m_mapping);
}
marshaller.marshal(m_d);
xmlData = baos.toByteArray();
baos.flush();
baos.close();
// Trace:
System.out.println("*** Marshalling completed successfully ***");
System.out.println(new String(xmlData));
}
catch (Exception e)
{
System.out.println("Marshalling failed !");
}
}
public static void main(String args[])
{
OnServerSide tester = new OnServerSide();
tester.marshall();
}
}
My simple mapping file:
<?xml version="1.0"?>
<!DOCTYPE databases PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.exolab.org/mapping.dtd";>
<mapping>
<class name="test.server.A" auto-complete="true" identity="reference">
<map-to xml="A"/>
<field name="reference" type="int">
<bind-xml node="attribute" />
</field>
</class>
<class name="test.server.B" auto-complete="true">
<map-to xml="B"/>
<field name="a" type="test.server.A">
<bind-xml name="REF_A" reference="true" node="attribute" />
</field>
</class>
<class name="test.server.C" auto-complete="true">
<map-to xml="C"/>
<field name="a" type="test.server.A">
<bind-xml name="REF_A" reference="true" node="attribute" />
</field>
</class>
<class name="test.server.D" auto-complete="true">
<map-to xml="D"/>
</class>
</mapping>
The result of the marshalling where the object a is missing:
<?xml version="1.0" encoding="UTF-8"?>
<D>
<b REF_A="15">
<type>XX25</type>
</b>
<number>123</number>
<c REF_A="15">
<category>C3</category>
</c>
</D>
Do you have any suggestion about my problem ?
