From source file:Hibernate.Util.HibernateUtil.java

private static org.w3c.dom.Document Configuracion(String dataBaseName, String userName, String password)
        throws FileNotFoundException, JDOMException, IOException {

    Document documentJDOM = new SAXBuilder().build(xmlFileURL);
    XPathExpression<Element> xPathExpression = XPathFactory.instance()
            .compile("/hibernate-configuration/session-factory/property", Filters.element());
    List<Element> elementList = xPathExpression.evaluate(documentJDOM);
    //Esto es relativo a en que posicin aparecen las lineas en el hibernate.cfg.xml
    elementList.get(2).setText(dataBaseName);
