    Default Cannot read files while running program from JAR-file

    Hello!

    I have a program that is a XML-parser, and it works fine when I'm running it from NetBeans. But when I create a JAR-file and run the very same program, it cannot find the xml file. Consider this small program that addresses my problem:

    import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.IOException;
    import java.io.InputStream;
    import javax.xml.parsers.DocumentBuilder;
    import javax.xml.parsers.DocumentBuilderFactory;
    import javax.xml.parsers.ParserConfigurationException;
    import org.w3c.dom.Document;
    import org.xml.sax.SAXException;
     
    public class XMLTest {
     
            Document d;
     
            public XMLTest() throws ParserConfigurationException, FileNotFoundException, IOException, SAXException {
     
                String docString = "C:\\someXML.xml";
                DocumentBuilderFactory dbf;
                dbf = DocumentBuilderFactory.newInstance();
     
                dbf.setValidating(true);
                dbf.setIgnoringElementContentWhitespace(true);
     
                DocumentBuilder db = dbf.newDocumentBuilder();
     
                InputStream in = new FileInputStream(docString);
     
                d = db.parse(in);
            }
     
     
        public static void main(String[] args) throws ParserConfigurationException, FileNotFoundException, IOException, SAXException {
     
            XMLTest t = new XMLTest();
        }
    }

    But when I create a JAR-file and run the very same program, it cannot find the xml file.
    I presume the code throws an exception? Please post the full error message/stack trace.
