hibernated.cfg.xml报错问题，快崩溃了。。。
两个hibernate.cfg.xml文件一模一样，可是一个总是报错，另外一个就没报错可以正常运行，我把两个文件一个单词一个单词的对照实在是照找不出错误，求大神帮忙看下。
文件A
<?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"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password"></property> <property name="hibernate.connection.url"> <![CDATA[ jdbc:mysql://localhost:3306/webdata?useUnicode=true&characterEncoding=utf8 ]]> </property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="show_sql">true</property> <property name="hbm2ddl.auto">update</property> <mapping resource="com/bart/entity/Seller.hbm.xml"/> <mapping resource="com/bart/entity/Student.hbm.xml"/> </session-factory> </hibernate-configuration>
文件B：
<?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" > <hibernate-configuration> <session-factory> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password"></property> <property name="hibernate.connection.url"> <![CDATA[ jdbc:mysql://localhost:3306/webdata?useUnicode=true&characterEncoding=utf8 ]]> </property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="show_sql">true</property> <property name="hbm2ddl.auto">update</property> <!-- 指定映射文件的路径 --> <mapping resource="com/bart/entity/Student.hbm.xml"/> </session-factory> </hibernate-configuration>
这时A和B的内容，A一直报错，我全选A文件删除然后粘贴为B文件就不报错了。太奇怪了。。。开发环境是MyEclipse 10，Hibernate包是4.3的
