Does javax.xml.transform.Transfomer close its streams?

[Ziv Ben-Eliahu <zi...@wirexn.com>]

I have the following code:

{
	File outputFile = new File("out.xml");
	Result outputResult = new StreamResult(outputFile);
	
	
	File inputFile = new File("in.xml");
	Result inputSource = new StreamSource(inputFile);
	
         Transformer transformer = javax.xml.transform.TransformerFactory
              .newInstance().newTransformer("stylesheet.xsl");
	transformer.transform(inputSource, outputResult);
}

The default transformer instance is:
com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl

After this code runs, I cannot delete the created "out.xml" file while 
JVM is running. If I use FileOutputStream instead of File, and close the 
stream myself, then I can delete the file.
It seems to me that the Java-1.5 default Transformer opens a stream and 
does not close it.
Anyone knows if there is a different reason?
If no, do you know a non-default Transformer that closes the stream 
(rather than creating a stream myself).

Thanks, Ziv.

Hi Ziv,

  You're evaluation is correct. Fortunately, it appears that this has  
been fixed in XSLTC at Apache (I haven't tried it myself, but can  
tell by reading the source code). Please see [1] about downloading  
and installing the Apache version.

  Thanks.
