XML Exception on saving the data

[Sultan Khadar]

Hi All,

I am using DOM parser to read and write XML data.
Whenever data is modified, the save() method from the Bean class is called by the handler class, to save the modified data.
It is working fine for the first time. But from the second time onwards, it is giving the following exceptio.

Please find the details below.

  
protected  synchronized void save(Document document) {

		try {
			URI uri = XPathBean.class.getResource(inputSourcePath).toURI();
			StringBuffer sb = new StringBuffer();
			sb.append(inputSourcePath);
			
			System.out.println("inputSourcePath:  " + inputSourcePath);
			System.out.println("Saving file.." + uri);
           
           
			// print
			OutputFormat format = new OutputFormat(document);
			format.setIndenting(true);

			// to generate output to console use this serializer
			// XMLSerializer serializer = new XMLSerializer(System.out, format);

			// to generate a file output use fileoutputstream instead of
			// system.out
			XMLSerializer serializer = new XMLSerializer(new FileOutputStream(
					new File(uri)), format);

			serializer.serialize(document);

		} catch (URISyntaxException uriSyntaxException) {
			uriSyntaxException.printStackTrace();
		} catch (IOException ie) {
			ie.printStackTrace();
		}
	}
