utility to generate xsd from java class

Question

I want to generate xsd for the following class

public class Node{
  private String value;
  private List<Node> childrens;

}

What is the best utility to generate xsd schema for such code

In general I want to implement simple tree. I'm already using jaxb for generating the classes from schema.

Answer 1

You can use the generateSchema API on JAXBContext to generate an XML schema:

import java.io.IOException;
import javax.xml.bind.*;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamResult;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Node.class);   
        jc.generateSchema(new SchemaOutputResolver() {

            @Override
            public Result createOutput(String namespaceURI, String suggestedFileName)
                throws IOException {
                return new StreamResult(suggestedFileName);
            }

        });

    }

}
