我必须使用Hibernate来制作我的项目。问题是我无法找到解决问题的方法。我无法编译我的程序，因为我遇到了一些问题（我在输出控制台下面复制了）
hibernate.cfg.xml中：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:hsql://localhost</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<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> -->
<mapping resource="events/Event.hbm.xml"/>
</session-factory>
</hibernate-configuration>
我的主要课很简单：
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Event theEvent = new Event();
theEvent.settitle(title);
theEvent.setdate(theDate);
session.save(theEvent);
session.getTransaction().commit();
当我尝试编译我的程序时，我得到的是这样的东西：

我该如何解决这个问题？
提前致谢！
编辑： 嗨！ 我再次更改了meskobalazs（在hibernate.cfg.xml中）提到的内容。 该程序继续运行，但仍然遇到一些错误和错误：
