есть файлик HibernateUtil, в котором прописано след.-ее: | Код |
static {
// Creating Path to database directory if it is not exists
String dbPath = javax.swing.filechooser.FileSystemView.getFileSystemView().getDefaultDirectory() + "/RS_Blog/RS_BlogDatabase";
Configuration conf = new Configuration();
conf.configure("hibernate.cfg.xml");
conf.setProperty("hibernate.connection.url", "jdbc:derby:" + dbPath + ";create=true");
conf.setProperty("connection.url", "jdbc:derby:" + dbPath + ";create=true");
sessionFactory = conf.buildSessionFactory();
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}

а в методе мэйн программы написано: | Код |
HibernateUtil.getSessionFactory();
|
Но, непонятно почему, ничего не создается. пишется ошибка: Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException at com.company.rs_blog.server.database.HibernateUtil.<clinit>(HibernateUtil.java:67) на строчку Configuration conf = new Configuration(); Кто-нибудь, подскажите, в чем дело?!  И как создать пустую базу???  |
