Formatted output with JAXB

Question

Hi, Please help me with the formatting of output XML file using JAXB. This is my client program that marshals xml content into xml file. This program is creating XML file with no indentation at all. I commented out the line
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
still getting same xml file with no indentation. Am I doing anything wrong?
Thanks in advance.
try {
// create a Validator
Validator v = jc.createValidator();
// validate the content tree
boolean valid = v.validate( root );
//logger.info("XML File Validated Successfully" );
     Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://mydomain.com/Schemas/data DT.xsd");
DataWriter writer = new DataWriter(
new OutputStreamWriter(new FileOutputStream(fileName),"UTF-8"),
"UTF-8" );
m.setProperty("com.sun.xml.bind.namespacePrefixMapper",new NamespacePrefixMapperImpl());
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
m.marshal(root, writer);
}catch( ValidationException ue ) {
logger.error( "Caught ValidationException"+ue ); throw new SdarsDBException("Validation Exception "+ue);
} catch( JAXBException je ) {
je.printStackTrace();
} catch( IOException ioe ) {
ioe.printStackTrace();

Hi,
try writing to the FileOutputStream directly.
I get formatted output this way.
maybe the DataWriter is doinfg some translatiopn for you?
