Indentation issues with Staxmate API

I am using Staxmate API to generate XML file. After reading the tutorial: http://staxmate.codehaus.org/Tutorial I tried making the changes in my code. At last I added the call

doc.setIndentation("\n  ", 1, 1);

Which causes the newly generated XML file to be empty! Without this method call entire XML file gets generated as expected.

Suspecting something fishy in in project setup, I created a Test class in the same package with the code given in tutorial:

package ch.synlogic.iaf.export;

import java.io.File;

import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamException;

import org.codehaus.staxmate.SMOutputFactory;
import org.codehaus.staxmate.out.SMOutputDo开发者_运维知识库cument;
import org.codehaus.staxmate.out.SMOutputElement;

public class Test {

public static void main(String[] args) {
 main("c:\\tmp\\empl.xml");
}

public static void main(String fname)
{
 // 1: need output factory
 SMOutputFactory outf = new SMOutputFactory(XMLOutputFactory.newInstance());
 SMOutputDocument doc;
 try {
  doc = outf.createOutputDocument(new File(fname));

 // (optional) 3: enable indentation (note spaces after backslash!)
 doc.setIndentation("\n  ", 1, 1);
 // 4. comment regarding generation time
 doc.addComment(" generated: "+new java.util.Date().toString());
 SMOutputElement empl = doc.addElement("employee");
 empl.addAttribute(/*namespace*/ null, "id", 123);
 SMOutputElement name = empl.addElement("name");
 name.addElement("first").addCharacters("Tatu");
 name.addElement("last").addCharacters("Saloranta");
 // 10. close the document to close elements, flush output
 doc.closeRoot();
 } catch (XMLStreamException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
}
}

Now when I invoke the main(String) method from my code the problem still persists whereas if I just run class Test as it is it works smoothly! My code involves database initializations and some other product specific actions.

I am lost, any thoughts on how should I proceed with this?


Indentation works with Woodstox API

WstxOutputFactory factory = new WstxOutputFactory();
factory.setProperty(WstxOutputFactory.P_AUTOMATIC_EMPTY_ELEMENTS, true);
SMOutputFactory outf = new SMOutputFactory(factory);
doc = outf.createOutputDocument(fout);
doc.setIndentation("\n  ", 1, 1);


Below works for me - context.setIndentation("\r\n\t\t\t\t\t\t\t\t", 2, 1); // indent by windows lf and 1 tab per level
