JMX error when deploying Petclinic on Tomcat 4.1.23

Hi,

I am trying to deploy the Petclinic sample on Tomcat and am getting the error below. I checked that the JMX class should be on Tomcat's classpath. Any idea on what needs to be configured?

GRAVE: Context initialization failed
org.springframework.beans.factory.BeanDefinitionSt oreException: Error registerin

ext-jdbc.xml]: Class that bean class [org.springframework.jmx.export.assembler.I

Thanks for any input

It looks like you dont have a JMX implementation on your class path. Check out http://mx4j.sourceforge.net.
