Question

我是eclipse的新手。我正在尝试使用Hibernate。 Java ee IDE版本Juno和Hibernate Tools版本3.5.1。在IDE的数据库开发中，我创建了一个数据源，并测试了连接，它工作正常。然后我创建了一个Hibernate配置文件hibernate.cfg.xml 然后我创建了一个Hibernate控制台配置当我尝试刷新控制台配置或当我尝试创建逆向工程文件时，我有错误“在发生内部错误：获取TestHiber01的子项。插件org.eclipse.core.jobs。所有错误日志都是：

eclipse.buildId=M20120914-1800

An internal error occurred during: "Fetching children of TestHiber01".

hibernate.cfg文件是：

<session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">XXXXX</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydb</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>

这是什么意思？为什么无法连接到数据库？

Hibernate Tools 3.5.1依赖于Eclipse Indigo。您遇到了兼容性问题。

当我使用JBoss Juno update site时，我看到可以安装此版本的Hibernate Tools：Hibernate Tools 3.6.0.Alpha1-v20120910-1507-H32。这是相应的JBoss issue。
