Why is my entire XML file all on one line?

Question

I am createing a XML file using DOM. The file is started as a new document and I add child nodes using the appendChild() function. I am also using the transformer class to write the file. The file output is as follows:
<?xml version="1.0" encoding="UTF-8"?><TestSystems><department>Tape<program>T10000A</program></department></TestSystems>
and I want it to be:
<?xml version="1.0" encoding="UTF-8"?>
<TestSystems>
<department>Tape
<program>T10000A</program>
</department>
</TestSystems>
How can I get a nicely formated file?
Here is my code:
import java.io.*;
import javax.xml.parsers.*;
import javax.xml.xpath.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.dom.DOMSource;
public class XMLTestClass {
    DocumentBuilderFactory domFactory;
    DocumentBuilder domBuilder;
    Document xmlDoc;
    String xmlFile = "c:\\test.xml";
    /** Creates a new instance of XMLTestClass */
    public XMLTestClass() {
        try{
            domFactory = DocumentBuilderFactory.newInstance();
            domBuilder = domFactory.newDocumentBuilder();
            //xmlDoc = domBuilder.parse(new File(xmlFile));
        //    xpath = XPathFactory.newInstance().newXPath();
        }//try
        catch (ParserConfigurationException e) {
            System.err.println("ParserConfigurationException caught...");
            e.printStackTrace();
    public void run(){
        System.out.println("Test");
        xmlDoc = domBuilder.newDocument();
        Element rootElement = xmlDoc.createElement("TestSystems");
        xmlDoc.appendChild(rootElement);
        Element deptElement = xmlDoc.createElement("department");
        deptElement.appendChild(xmlDoc.createTextNode("Tape"));
        rootElement.appendChild(deptElement);
        Element progElement = xmlDoc.createElement("program");
        progElement.appendChild(xmlDoc.createTextNode("T10000A"));      
        deptElement.appendChild(progElement);   
        try{
            TransformerFactory tf = TransformerFactory.newInstance();
            Transformer transform = tf.newTransformer();
            Source src = new DOMSource(xmlDoc);
            Result dest = new StreamResult(new File(xmlFile));
            transform.transform(src, dest);
        catch(Exception exp){}
    public static void main(String[] args){
        XMLTestClass xml = new XMLTestClass();
        xml.run();
}

Thanks for the tip. The code sort of works now but the funny thing is that the file output does not indent, but is no longer on one line. The out put is now (no indents):
<?xml version="1.0" encoding="UTF-8"?>
<TestSystems>
<department>Tape<program>T10000A</program>
</department>
</TestSystems>
Also the line
transform.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
[\code]
does not seem to have any affect.
