<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   -->

Answer 2

一个XML文档的DOCTYPE描述信息中指定的根元素名称必须和实际文档中的根元素名称相同 
而你现在的是:
描述中定义:hibernate-configuration 
实际根元素:hibernate-mapping所以你的描述信息需要写成如下:
<!DOCTYPE hibernate-mapping PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

Answer 3

就是用hibernate3.0连接数据库呀，那个是我的配制文件，就是那个配制文件有问题，我不知道怎么改

Answer 4

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--

<hibernate-mapping>
    <class name="com.oa.pojos.Users" table="users" schema="dbo" catalog="OASystem">
        <id name="uid" type="java.lang.Integer">
            <column name="uid" />
            <generator class="native" />
        </id>

<!DOCTYPE hibernate-mapping PUBLIC
      "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping package="hibernate_tier">        <class name="hibernate_tier.Train"  table="TRAIN">
                
                <id name="id" >
                        <generator class="increment"/>
                </id>         <property name="trainCode" column="train_code" type="string"/>
        <property name="startStation" column="start_station" type="string"/>
<property name="startTime" column="start_time" type="time"/>
