Tags not printed when outputting XML after XSLT transformation

Question

Hi!
I want my to perform an XSLT transformation on requests to my web service.
This is the style of a typical request:
<app:aRequest xmlns:app="http://myNamespace">
  <app:firstTag>value1</app:firstTag>
  <app:secondTag>value2</app:secondTag>
  <app:thirdTag>value3</app:thirdTag>
</app:aRequest>I want to transform it into something like this:
<app:aRequest xmlns:app="http://myNamespace">
  <app:firstTag>A hard coded, completely different value!</app:firstTag>
  <app:secondTag>value2</app:secondTag>
  <app:thirdTag>value3</app:thirdTag>
</app:aRequest>To do that, I use the following XSLT:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:app="http://myNamespace">
<xsl:template match="/">
<app:aRequest>
  <app:firstTag>A hard coded, completely different value!</app:firstTag>
  <app:secondTag><xsl:value-of select="app:aRequest/app:secondTag" /></app:secondTag>
  <app:thirdTag><xsl:value-of select="app:aRequest/app:thirdTag" /></app:thirdTag>
</app:aRequest>
</xsl:template>
</xsl:stylesheet>And I use the following code to execute the transformation:
public Object unmarshal(Source source) throws XmlMappingException, IOException {
  TransformerFactory factory = TransformerFactory.newInstance();
    // Does this factory support SAX features?
    if(factory.getFeature(SAXSource.FEATURE)) {
      SAXTransformerFactory saxTransformerFactory = (SAXTransformerFactory)factory;
    // Read xslt file.
    InputStream inputStream = getClass().getResourceAsStream("/META-INF/xsltTransformation.xsl");
    if(inputStream == null) {
      throw new RuntimeException("No XSLT transformation file present at " + location);
    Templates xsltOutputTemplate = saxTransformerFactory.newTemplates(new StreamSource(inputStream));
    Transformer transformer = xsltTemplate.newTransformer();
    // Perform transformation.
    StringWriter stringWriter = new StringWriter();
    StreamResult result = new StreamResult(stringWriter);
    transformer.transform(source, result);
    // Print result.
    String xmlString = stringWriter.toString();
    System.out.println(xmlString);
    // Proceed with unmarshalling.
    StringReader stringReader = new StringReader(xmlString);
    StreamSource transformedSource = new StreamSource(stringReader);
    return oxMapper.getUnmarshaller().unmarshal(transformedSource);
}However, the System.out.println(xmlString); produces the following result:
<?xml version="1.0" encoding="UTF-8"?>
  value1
  value2
  value3The tags are not printed and the hard coded value is not present.
What am I doing wrong? Please help!

Following up on what the good Dr said,
Are you sure that you are using the stylesheet that you think you are?
I tried your stylesheet and input and got more or less what you wanted and not what you actually got.
Note that I did not use your code.
