Я следую Java Hibernate учебник пример с YouTube. Все выглядит отлично, пока я не попытаюсь запустить код, который должен создать таблицу Employee на сервере Apache Derby. Сначала я попытался использовать SQL-сервер (2008), и я получил ту же ошибку.
Не удалось проанализировать конфигурацию: hibernate.cfg.xml , также существует ошибка тайм-аута . Я ценю любую помощь. Спасибо.
Вот ошибка, которую я получаю:

Вот мой файл hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>
<property name="connection.url">jdbc:derby://localhost:1527/HibernateDb;create=true</property>
<property name="connection.username">user</property>
<property name="connection.password">password</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">2</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.DerbyDialect</property>
<!-- Enable Hibernate's current session context -->
<property name="current_session_context_class">thread</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
</session-factory>
</hibernate-configuration>
И вот код, который я запускаю:
package com.hibernate.chapter1;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class TestEmployee {
public static void main(String[] args) {
AnnotationConfiguration config = new AnnotationConfiguration();
config.addAnnotatedClass(Employee.class);
config.configure("hibernate.cfg.xml");
new SchemaExport(config).create(true, true);
}
}
Что я сделал не так?
