title: How to read XML document with JiBX?
body: <p>I try to do example code </p>
  
  <pre><code>public class xml_class {

       * Unmarshal the sample document from a file, compute and set order total, then
       * marshal it back out to another file.

                  total += item.getPrice() * item.getQuantity();
              }
              order.setTotal(new Float(total));
  
              // marshal object back out to file (with nice indentation, as UTF-8)

  <p>And get an error:</p>
  
  <pre><code>Unable to access binding information for class test.Order

  <p>What is binding? And how to use it?</p>
