File or XSLT issue?

Hi,

I've been trying to get an xslt working within java but with no luck.
What I'm trying to do is upload a file and execute an XSLT on it. I
don't have much experience with either File or XSLT but what I've
found happening is the data in the file is being completly deleted!?!

The error I'm getting back is:

ERROR: 'Premature end of file.'
ERROR:
'com.sun.org.apache.xml.internal.utils.WrappedRuntimeException:
Premature end of file.'

It could be the way I'm reading the file into the java and not to do
with xslt?

Thanks for your help,

Gaffer

This is code I have for the button listener:

saveb.addSelectionListener(new SelectionAdapter(){
                    public void widgetSelected(SelectionEvent e) {

                        try{

                            String fileNamePublish = qmediafile_loc.getText(); //file
slected at runtime

                            FileOutputStream fos = new
FileOutputStream(fileNamePublish);

                            File xmlFile = new File(fileNamePublish);

                            File xsltFile = new File("C:/test.xsl");

                            Source xmlSource = new StreamSource(xmlFile);
                            Source xsltSource = new StreamSource(xsltFile);

                            TransformerFactory transFact =
TransformerFactory.newInstance();

                            try{

                             Transformer trans =
transFact.newTransformer(xsltSource);

                             trans.transform(xmlSource, new
StreamResult(System.out));
                            }catch(TransformerException me ) {}

                            }catch(IOException ioe) {}

                    }
                });
