Need help in formatting JAXB output

Question

I have some objects let\'s say two, A and B. These objects from the same class. I need to marshal these objects using JAXB and the output XML should be in this form:

Answer 1

Try this:

import java.io.StringWriter;
import javax.xml.bind.Marshaller;

...

Object requestObject = ...  // This is the object that needs to be printed with indentation
Marshaller marshaller = ...
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
StringWriter stringWriter = new StringWriter();
marshaller.marshal(requestObject, stringWriter);

System.out.println(stringWriter.toString());
