一个由hbm.xml文件格式不正确引发的悲催

项目中运用了Hibernate3,报错如下：

ctionInfo -> demo_ST_MANAGESECTIONINFO

xml配置文件如下：

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

    </id>
   <property
        name="stationId"

        column="STATIONID"
        length="64"
    />
   <property

</class>
<query name="getPDAsByStationId">
	from PDA c
	where c.stationId = :stationId
</query>
<query name="getRecordCountByPDANo">
	select count(*) as recordCount from PDA c

</query>
<query name="deletePDAsByStationId">
	delete from PDA c
	where c.stationId = :stationId
</query>
</hibernate-mapping>

看不出错在哪里吧，哈哈，真正的错误原因就在xml文件的第一行是空行，去掉空行就正确了，看命令行错误提示“Error parsing XML”后，只知道是这个配置文件的问题，查看字段和hql,没有找到原因（能找到才怪 ），确实很悲催吧。。
