I have a problem when I try to unmarshal XML to Java.
I first created my java files throught a XML schema:

And then I used the objects to marshal data into xml.
Marshalling works fine but unmarshalling don't.

I use this object for unmarshalling:

package marshalling;

import java.rmi.MarshalException;

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

import addressBook.Global;
import addressBook.model.generated.ClientsList;

public class ConvertXMLToJava {

public ConvertXMLToJava()
throws FileNotFoundException, MarshalException,

JAXBContext jc = JAXBContext.newInstance( Global.JAXB_PACKAGE,

// Create the unmarshaller
Unmarshaller unmarshaller = jc.createUnmarshaller();

// Unmarshal the object
JAXBElement list = (JAXBElement) unmarshaller.unmarshal(getFileStream());

Marshaller m = jc.createMarshaller();
m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );
m.marshal( list, System.out );


private FileInputStream getFileStream(){
return new FileInputStream(Global.XML_OUTPUT_FILE);
}catch(FileNotFoundException e){
return null;

This is the only thing I get if I unmarshall the XML file:

Convert XML to Java!
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Can anybody help me please?

Thanks in advance

When you are suspecting a bug and posting long code/xml fragments like this, please consider using the issuetracker at

Between the stripping of indentation, use of emoticon, and etc, this forum isn't a good place to do a trouble-shooting.
