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

[Santiago Pericas-Geertsen]

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.

I have the following code:

        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.
