How to generate a pojo class ( in jvm) from a xml?

Question

I have a xml :

<Employee>
   <name>xyz</name>
   <age>50</age>
   <salary>111</salary>
</Employee>

now how can I create a class dynamically in jvm from this xml ?? How to create setter/getter for this class ?

NOTE:: In future these xml elements can increase.

Here is an example to parse your XML file with JDOM2

import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.input.SAXBuilder;

public class Test {

  public static void main(String[] args) throws Exception {
    Document document = new SAXBuilder().build(Test.class.getResourceAsStream("test.xml"));

    for(Element elt :document.getRootElement().getChildren()) {
      System.out.println("tag : "+elt.getName());
      System.out.println("value : " + elt.getText()+"\n");
    }
  }
}

Output :

tag : name
value : xyz

tag : age
value : 50

tag : salary
value : 111

After that, you can

• Store the values in a Map OR
• Generate a .java file (I suggest to do it via Freemarker) and compile it.
