Dear fellow Java developers:

I have written some java code that creates an xml document, but I'm having trouble SAVING it on to my local pc as an xml file.  I thought it would be similar to writing a text file, but I am a bit off.  I have listed my code below, and I think I'm almost there, but not quite.  When I run my code, I get the following content within my document.xml file:

[#document: null]

Any help would be greatly appreciated.  Thanks to all who reply.

import java.io.*;

import javax.xml.parsers.*;

import javax.xml.transform.*;

import javax.xml.transform.dom.*;

import javax.xml.transform.stream.*;

import org.w3c.dom.*;

 

public class CreateXMLDoc {

	

	PrintWriter updates;

	

	public static void main(String[] args) throws Exception {

		String root = "transmission";

		DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();

        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

        Document document = documentBuilder.newDocument();

		Element rootElement = document.createElement(root);

        document.appendChild(rootElement);

		

		

			String element = "message";

			

			String data = "text";

			Element em = document.createElement(element);

			em.appendChild(document.createTextNode(data));

			rootElement.appendChild(em);

		

		TransformerFactory transformerFactory = TransformerFactory.newInstance();

        Transformer transformer = transformerFactory.newTransformer();

        DOMSource source = new DOMSource(document);

        StreamResult result =  new StreamResult(System.out);

        transformer.transform(source, result);

        

        CreateXMLDoc testCode = new CreateXMLDoc();

        testCode.fileWrite(document);

	}

        

        public void fileWrite(Document doc){

        

        try  

        {     

        	updates = new PrintWriter(new BufferedWriter(new FileWriter("c:\\document.xml")), true);

        }  

        catch(Exception e)

        {   e.printStackTrace();

             return;

        }

        updates.println(doc);

	}

I changed the following line in your code:
StreamResult result =  new StreamResult(new File("c:\\document.xml"));

And commented this call:
 //testCode.fileWrite(document);

Check the attached code:

import java.io.*;

import javax.xml.parsers.*;

import javax.xml.transform.*;

import javax.xml.transform.dom.*;

import javax.xml.transform.stream.*;

import org.w3c.dom.*;

 

public class CreateXMLDoc {

        

        PrintWriter updates;

        

        public static void main(String[] args) throws Exception {

                String root = "transmission";

                DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();

        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

        Document document = documentBuilder.newDocument();

                Element rootElement = document.createElement(root);

        document.appendChild(rootElement);

                

                

                        String element = "message";

                        

                        String data = "text";

                        Element em = document.createElement(element);

                        em.appendChild(document.createTextNode(data));

                        rootElement.appendChild(em);

                

                TransformerFactory transformerFactory = TransformerFactory.newInstance();

        Transformer transformer = transformerFactory.newTransformer();

        DOMSource source = new DOMSource(document);

        StreamResult result =  new StreamResult(new File("c:\\document.xml"));

        transformer.transform(source, result);

        

        CreateXMLDoc testCode = new CreateXMLDoc();

        //testCode.fileWrite(document);

        }

        

        public void fileWrite(Document doc){

        

        try  

        {     

                updates = new PrintWriter(new BufferedWriter(new FileWriter("c:\\document.xml")), true);

        }  

        catch(Exception e)

        {   e.printStackTrace();

             return;

        }

        updates.println(doc);

        }

 

}
