Using binded classes in your code - JIBX

Question

I managed to bind the files generated through an XSD successfully and i got the following files in my dir

C:\jibx\tutorial\example25>dir
Volume in drive C is WINDOWS
Volume Serial Number is 1C8F-663E

Directory of C:\jibx\tutorial\example25

05/06/2012  07:12 PM    <DIR>          .

           2 Dir(s)  160,023,375,872 bytes free

Now i copied these files into a newly created JAVA project in eclipse , created a package called example25 in that project and pasted those files there I then used the following code and ran it in the debug mode

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.util.Iterator;

import org.jibx.runtime.BindingDirectory;
import org.jibx.runtime.IBindingFactory;
import org.jibx.runtime.IMarshallingContext;
import org.jibx.runtime.IUnmarshallingContext;
import org.jibx.runtime.JiBXException;
import example25.*;


public class Test
{

public static void main(String[] args)
{

        try
        {

            // unmarshal customer information from file
            IBindingFactory bfact = BindingDirectory.getFactory(Order.class);
            IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
            FileInputStream in = new FileInputStream("D:\\Java Libraries\\jibx\\dwcode2\\starter.xml");
            Order order = (Order)uctx.unmarshalDocument(in, null);

            // compute the total amount of the order
            float total = 0.0f;
            for (Iterator<Item> iter = order.getItemList().iterator(); iter.hasNext();)
            {
                Item item = iter.next();
                total += item.getPrice() * item.getQuantity();
            }
            order.setTotal(new Float(total));

            // marshal object back out to file (with nice indentation, as UTF-8)
            IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(2);
            FileOutputStream out = new FileOutputStream("c:\\out.xml");
            mctx.setOutput(out, null);
            mctx.marshalDocument(order);
            System.out.println("Processed order with " +  order.getItemList().size() + " items and total value " + total);

        }
        catch (FileNotFoundException e)
        {
            e.printStackTrace();
            System.exit(1);
        } catch (JiBXException e)
        {
            e.printStackTrace();
            System.exit(1);
        }
    }

}//end main

I get the following error after the execution of the first statement

Unable to access binding information for class example25.Order
Make sure the binding has been compiled
java.lang.NoSuchFieldException: JiBX_bindingList

Rajesh,

The files that you show in that directory mean you did everything correctly!

The mistake you made was to use eclipse, since eclipse automatically compiles the source code files again (without the binding information you added in the binding step)

Try running the Test.class file with the class files you generated in the first step.

Your java command should be something like this:

java -cp C:\directorywithtestclass;C:\jibx\tutorial Test
