Hi Derek,

I've tried this but nothing has changed. I guess then I have not constructed my mapping file in the proper way(?).

Thanks a lot,

Christos

Looks like you're not using the mapping file, try:

Mapping map=new Mapping();

map.loadMapping("mapping.xml");

File file = new File("qosProfile.xml");

Writer writer = new FileWriter(file);

Marshaller marshaller=new Marshaller(writer);

marshaller.setMapping(map);

marshaller.marshal(qp); // CHANGE MADE HERE.

Hi,

I'm using Castor 0.9.5.2 and I'm facing the following problem:

I try to export to an XML file an object named QosProfile which is a collection of objects named UmtsQos:

QosProfile:

public class QosProfile {
//
private ArrayList listUmtsQos;
//
public QosProfile()
{
  listUmtsQos = new ArrayList();
}
//
public ArrayList getUmtsQos(){

  return listUmtsQos;
}
//
public void add(UmtsQos umts){
//
  listUmtsQos.add(umts);
}
//
  public void remove(UmtsQos umts){
//
  listUmtsQos.remove(umts);
}
//
}

where UmtsQos is a simple class with a simple constructor and setXXX / getXXX methods containing the following attributes :

public int trafficClass;
public int maxBer;

The mapping I use is the following :

<!DOCTYPE databases PUBLIC
"-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"mapping.dtd">
<mapping>
<description>QosProfile mapping example</description>
   <class name="QosProfile">
    <field name="umtsqos" type="UmtsQos" collection="collection">
      <bind-xml name="umtsqos"/>
    </field>
    </class>
<class name="UmtsQos" auto-complete="true">
       <field name="trafficClass">
         <bind-xml name="trafficClass" node="attribute"/>
     </field>
      <field name="maxBer">
         <bind-xml name="maxBer" node="attribute"/>
     </field>

</class>
</mapping>

and the test program :

public class TestQosProfileXML
{
    public static void main(String[] argv) {

// build a test bean based on QosProfile class
    QosProfile qp=new QosProfile();

  UmtsQos umts = new UmtsQos();
  umts.setMaxBer(5);

  umts.setTrafficClass(2);

UmtsQos umts2 = new UmtsQos();
  umts2.setMaxBer(15);

  umts.setTrafficClass(12);

  qp.add(umts);
  qp.add(umts2);

  try {

   // write it out as XML

   Mapping map=new Mapping();
   map.loadMapping("mapping.xml");
   File file = new File("qosProfile.xml");

    Writer writer = new FileWriter(file);
   Marshaller marshaller=new Marshaller(writer);
   marshaller.setMapping(map);
   Marshaller.marshal(qp,writer);



    } catch (FileNotFoundException ex) {
            ex.printStackTrace(System.err);
    } catch (IOException ex) {
            ex.printStackTrace(System.err);
    } catch (MarshalException ex) {
            ex.printStackTrace(System.err);
        } catch (MappingException ex) {
            ex.printStackTrace(System.err);
        }catch (ValidationException ex) {
            ex.printStackTrace(System.err);
  }
   }
}

When I run the test program I get several errors:

org.exolab.castor.mapping.MappingException: Could not find the class QosProfile

at gr.uoa.di.cnl.test.TestQosProfileXML.main(TestQosProfileXML.java:69) ---------------------------> marshaller.setMapping(map);

        Any directions would be of great help .

        Thank you,
