Hi! I am a beginner of JAXB too. I have tried changing your program and got results. I am printing the program changes and corresponding output below. Hope this helps you. (Bold text in the program indicates changes)1) First I made the changes as below./////////////////////////////////////JAVA PROGRAMimport java.io.FileInputStream;import java.io.FileOutputStream;import java.io.File;import java.io.IOException;import java.util.Iterator;import java.util.List;import java.math.*;import javax.xml.bind.JAXBContext;import javax.xml.bind.JAXBException;import javax.xml.bind.Unmarshaller;import javax.xml.bind.Marshaller;import test.jaxb.*;public class New{public static void main( String[] args ){try{JAXBContext jc = JAXBContext.newInstance( "test.jaxb" );ObjectFactory objFactory = new ObjectFactory();Marshaller mar = jc.createMarshaller();mar.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT ,new Boolean(true));CollectionType ctype = objFactory.createCollectionType();Collection cc = objFacto
ry.createCollection();List lst1 = ctype.getChoice();ChoiceType chtype = objFactory.createChoiceType();Choice ch1 = objFactory.createChoice();ch1.setSnumber(1);ch1.setAnswerchoice("Old");lst1.add(ch1);mar.marshal(ctype, System.out);}catch( JAXBException je ){je.printStackTrace();}catch( Exception ioe ){ioe.printStackTrace();}}}OUTPUT:<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Choice snumber="1"><answerchoice>Old</answerchoice></Choice>2) Then, I have tried this./////////////////////////////////////JAVA PROGRAMimport java.io.FileInputStream;import java.io.FileOutputStream;import java.io.File;import java.io.IOException;import java.util.Iterator;import java.util.List;import java.math.*;import javax.xml.bind.JAXBContext;import javax.xml.bind.JAXBException;import javax.xml.bind.Unmarshaller;import javax.xml.bind.Marshaller;import test.jaxb.*;public class New{public static void main( String[] args ){try{JAXBContext jc = JAXBContext.newInst

Added a property to marshaller.

import javax.xml.bind.JAXBContext;import javax.xml.bind.JAXBException;import javax.xml.bind.Unmarshaller;import javax.xml.bind.Marshaller;
import test.jaxb.*;
public class New{public static void main( String[] args ){try{JAXBContext jc = JAXBContext.newInstance( "test.jaxb" );ObjectFactory objFactory = new ObjectFactory();
Marshaller mar = jc.createMarshaller();mar.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT ,new Boolean(true));
CollectionType ctype = objFactory.createCollectionType();Collection cc = objFactory.createCollection();
List lst1 = cc.getChoice();
ChoiceType chtype = objFactory.createChoiceType();Choice ch1 = objFactory.createChoice();ch1.setSnumber(1);ch1.setAnswerchoice("Old");
lst1.add(ch1);mar.setProperty(Marshaller.JAXB_NO_NAMESPACE_SCHEMA_LOCATION , "c:jaxb1.0binTest.xsd");mar.marshal(cc, System.out);
}catch( JAXBException je ){je.printStackTrace();}catch( Exception ioe ){ioe.printStackTrace();}}}
OUTPUT:

I am trying to create a content tree by using the following java code below. Before creating the content tree, I have parsed the XML Schema and got the JAXB classes. I have to genetate the following content tree, but my program below doesnot do that. Please check this piece of code and tell me where I am making a mistake? Is the Schema wrong or the Java Program I have written is wrong.
