请问，如何使用Proxool配置JNDI数据源，急

目前的配置文件如下：
Proxool.xml<?xml version="1.0" encoding="UTF-8"?>
<something-else-entirely>
    <proxool>
        <alias>DBPool</alias>
        <driver-url>jdbc:oracle:thin:@127.0.0.16:1521:ora</driver-url>
        <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
        <driver-properties>
            <property name="user" value="test"/>
            <property name="password" value="1234"/>
        </driver-properties>        <maximum-connection-count>10</maximum-connection-count>
        <house-keeping-test-sql>select sysdate from dual</house-keeping-test-sql>        <jndi-name>jdbc/mydatasource</jndi-name>
        <jndi-java.naming.factory.initial>com.caucho.naming.InitialContextFactoryImpl</jndi-java.naming.factory.initial>
        <jndi-java.naming.provider.url>localhost:1099</jndi-java.naming.provider.url>
    </proxool>
</something-else-entirely>
在web.xml加入了
 <servlet>
      <servlet-name>proxoolServletConfigurator</servlet-name>
    <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
     <init-param>
       <param-name>xmlFile</param-name>
       <param-value>WEB-INF/src/proxool.xml</param-value>
     </init-param>
     <load-on-startup>1</load-on-startup>
   </servlet>启动Tomcat初始化Proxool时总是报如下错误：2007-03-12 14:00:11] [INFO ]  initialize Log4j over...
