The filename or extension is too long!! When Passing XML file

I am reading an XML file from server and then parsing it to save as csv file. I am getting an error mentioned in the subject. Any idea how i can overcome this??

this is my code:

private void CreateXML2CSV(String inputStream) {
    try {
        File stylesheet = new File("src/main/resources/adv_cat.xsl");
        File xmlSource = new File(inputStream); // Error occurs here !!!. Inputstream is my xml string


        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document document = builder.parse(xmlSource);

        StreamSource stylesource = new StreamSource(stylesheet);
        Transformer transformer = TransformerFactory.newInstance()
                .newTransformer(stylesource);
        Source source = new DOMSource(document);
        Result outputTarget = new StreamResult(new File("src/main/resources/adv_cat.csv"));
        transformer.transform(source, outputTarget);
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (TransformerConfigurationException e) {
        e.printStackTrace();
    } catch (TransformerException e) {
        e.printStackTrace();
    }
    System.out.println("writeToFile Success!");
}

This is the error message:

java.io.FileNotFoundException: C:\Users\Lincube\workspace\Liverail\<?xml version="1.0" encoding="UTF-8"?><liverailapi requested=".....<\executiontime><\liverailapi> (<\executiontime><\liverailapi> (The filename or extension is too long))
