proxool连接池与hibernate的问题求解?

[songfuqiang]

我才开始学习hibernate,使用JDBC时可正常使用,但是我加如了proxool连接池就发生以下错误:
%%%% Error Creating SessionFactory %%%%
org.hibernate.HibernateException: Unable to locate config file: proxoolconf.xml

我的配置文件如下:
<?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="dialect"></property>
<property name="proxool.pool_alias">SBPool</property>
<property name="jdbc.fetch_size">50</property>
<property name="proxool.xml">proxoolconf.xml</property>
<property name="connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider
</property>

<!--

-->
<mapping resource="com/hibernate/hbm/Employ.hbm.xml" />
</session-factory>
</hibernate-configuration>

使用注释的配置就能成功运行.
请问这是怎么回事?
