Tomcat6下部署BTM的问题

主要参考http://docs.codehaus.org/display/BTM/Tomcat2x进行配置，可是出现了下面的错误：2012-9-10 10:12:13 org.apache.catalina.core.NamingContextListener addResource
警告: Failed to register in JMX: javax.naming.NamingException: no resource registered with uniqueName 'jdbc/MYSQL', available resources: []下面是我的tomcat配置:
btm-config.properties：bitronix.tm.serverId=tomcat-btm-node0
bitronix.tm.journal.disk.logPart1Filename=${btm.root}/work/btm1.tlog
bitronix.tm.journal.disk.logPart2Filename=${btm.root}/work/btm2.tlog
