Re: [Springframework-developer] JMX Documentation or Sample

[Scott B. <sco...@ru...>]

Just in case any one else is looking at the example Michael provided, 
not only is JmxMBeanAdapter renamed to MBeanExporter, the 
MBeanServerFactoryBean is located under support not factory (found that 
out the hard way ;-))

Michael, Thomas or Rob.  Have you guys seen this error in relation to 
the JMX support?:

I got this on Tomcat 5.0.27 and 5.0.30-beta.  I tried to connect using 
jconsole in JDK 5 and connecting to a remote server of localhost:9876 (I 
also tried on port 10,000)
