XML binding using JiBX

JiBX is a XML binding framework which binds XML to your java class.
XML binding is a 2 phase process:
1. JiBX uses binding definition to define the rule how conversion wil happen and modifies byte code of the class.
2. In phase 2 JiBX runtime does marshalling and un-marshalling of java objects to populate XML to java and java 2 XML.

Algorithm

• Add following jar files to your lib directory from JiBX distribution
1. bcel.jar (Byte Code Engineering Library used to change bytecode for the class)
2. jibx-bind.jar (1,2 are used in phase I)
3. jibx-run.jar
4. jibx-extras.jar
5. xpp3.jar (3,4,5 are used in phase II)
• Modify java class using binding compiler (java -jar ../lib/jibx-bind.jar binding.xml)
• Write code for marshalling and unmarshalling of java object

Example:

public void XML2Java2XML() {
  try {
   IBindingFactory bfact = BindingDirectory.getFactory(Customer.class);   
   IUnmarshallingContext uctx = bfact.createUnmarshallingContext();

   Object obj = uctx.unmarshalDocument
        (new FileInputStream("customer.xml"), null);
   Customer customer = (Customer)obj;
   System.out.print(customer.toString());
   
   IMarshallingContext mctx = bfact.createMarshallingContext();
      mctx.setIndent(4);
      mctx.marshalDocument(obj, "UTF-8", null,
          new FileOutputStream("customer2.xml"));
      
  } catch (FileNotFoundException e) {   
   e.printStackTrace();
  } catch (JiBXException e) { 
   e.printStackTrace();
  }
 }
