警告未能在JMX中注册：javax.naming.NamingException-tomcat dbcp2

我正在使用apache-tomcat-6.0.35并将DB池Jar升级为commons-dbcp2-2.1.1.Jar和commons-pool2-2.4.2.Jar 我在apache-tomcat-6.0.35/conf/context.xml文件中做了以下更改

<Resource auth="Container"
description="ebook DB Connection"
driverClassName="oracle.jdbc.OracleDriver"
name="jdbc/ebookDS"
username="username"
password="password"
factory="org.apache.commons.dbcp2.BasicDataSourceFactory"
type="javax.sql.DataSource"
url="jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = cluster-b3-10)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = eb11dc) ))"
maxTotal="100"
maxIdle="20"
maxWaitMillis="30000"
accessToUnderlyingConnectionAllowed="true" />

任何关于这里发生的事情的信息都将不胜感激
