与远程MySql服务器的{Hibernate连接

Question

我一直在尝试从局域网访问MySql服务器，它与＃34; localhost＆＃34; ，但无法从Hibernate远程访问服务器。

MySql querybrowser是一个能够访问远程服务器，Ping工作正常，浏览过SO和互联网的错误，我每次都会得到：

通讯链接错误 和 无法读取服务器的响应。预计读取4个字节，在连接意外丢失之前读取0个字节。

这是Hibernate.cfg.xml

<hibernate-configuration>
    <session-factory>
        <property name="connection.driver_class">
            com.mysql.jdbc.Driver
        </property>
        <property name="connection.url">
            jdbc:mysql://192.168.0.15:3306/emrp  
        </property>
        <property name="connection.username">username</property>
        <property name="connection.password">password</property>
        <property name="connection.pool_size">10</property>
        <property name="dialect">
            org.hibernate.dialect.MySQLDialect
        </property>
        <property name="current_session_context_class">thread</property>
        <property name="cache.provider_class">
            org.hibernate.cache.NoCacheProvider
        </property>
        <property name="show_sql">true</property>
        <property name="hbm2ddl.auto">update</property>
</hibernate-configuration>

连接超时，防火墙端口，权限授予，所有事情都已经过尝试但似乎错误。

这些是我们使用的工具和技术： 日食， 雄猫， 休眠4 Mysql 5 Struts 2

注意：Telnet 192.168.0.15 3306有效，能够从mysql查询浏览器连接，

请在这里指导我。
