TOMCAT4.1下配置JNDI数据源的问题

我在TOMCAT下配置oracle的JNDI数据源在运行时遇到以下问题:
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context

........
........





看到这异常我知道是我的JNDI好象没有配置对
于是我又查看了一下server.xml
下面是我配置的文件:

<Context className="org.apache.catalina.core.StandardContext" cachingAllowed="true" charsetMapperClass="org.apache.catalina.util.CharsetMapper" cookies="true" crossContext="false" debug="0" displayName="Welcome to Tomcat" docBase="D:\Tomcat 4.1\webapps\ROOT" mapperClass="org.apache.catalina.core.StandardContextMapper" path="" privileged="false" reloadable="false" swallowOutput="false" useNaming="true" workDir="work\Standalone\localhost\_" wrapperClass="org.apache.catalina.core.StandardWrapper">
<Resource name="jdbc/OracleDB" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/OracleDB">
<parameter>
<name>maxWait</name>
<value>5000</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>2000</value>
</parameter>
<parameter>
<name>password</name>
<value>*****12</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:thin@192.168.18.200:1521:cqlove2</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>2</value>
</parameter>
<parameter>
<name>username</name>
<value>cqlove</value>
</parameter>
</ResourceParams>
</Context>




以上代码参数配置都是正确的~
但是却报出了异常~
请高手给出解决方法~
