I have the following binding file in a folder called example 24

<binding xmlns:tns="ns" package="example24" name="binding"
trim-whitespace="true">
  <namespace uri="ns" default="elements" prefix="tns"/>

<mapping abstract="true" type-name="tns:item" class="example24.Item">
    <value style="attribute" name="id" get-method="getId"
set-method="setId"/>
    <value style="attribute" name="quantity" get-method="getQuantity"
set-method="setQuantity"/>
    <value style="attribute" name="price" get-method="getPrice"
set-method="setPrice"/>
  </mapping>
</binding>

and the code for Item (Item.java) is placed next to binding.xml
package example24;
public class Item
{
    private String id;
    private int quantity;
    private Float price;

    public String getId()
    { return id; }


    public void setId(String id)
    {  this.id = id;    }

    public int getQuantity()
    {  return quantity; }


    public void setQuantity(int quantity)
    {  this.quantity = quantity; }


    public Float getPrice()
    { return price; }

    public void setPrice(Float price)
    {   this.price = price;   }
}

And to generate the binding here is what i do and the output i get
C:\jibx\tutorial>java -jar C:\jibx\lib\jibx-bind.jar example24\binding.xml
Error: Cannot find information for class example24.Item; on mapping element
at (
line 4, col 71, in binding.xml)

Any suggestions ??
