Can I get your 2 cents?
I sent this yesterday. I am hoping someone can let me know as why this
is occurring or maybe give me some ideas of things to look at. Any help
would be greatly appreciated!
I am running Apache 2.0.52, jk2 2.0.4, and Tomcat 5.0.28. Recently I
changed the version of Java that Tomcat is using from IBM jdk 1.4.1 to
Sun jdk 1.6. Since then I get the following messages in the
catalina.out file every 5 minutes or so:
Mar 20, 2007 11:59:46 AM org.apache.commons.modeler.Registry

Thanks for the response. I will pass this along to the developers. I
am only the administrator of this application. Wish I knew more about it!

I'll assume you're not using reflection to acquire the bean object and If you dont mind a code solution
I found this wrapper class for JMX which performs all the necessary functions for the Java Management Bean

From what I have read in a Tomcat book this is related to JMX. If I
understand it correctly JMX is optional. Anyone know how to turn it off?

The error is:
Caused by: java.lang.IllegalArgumentException: Object name cannot be null
This error occurs when you use Java Reflection to reference an obj. Are you
using some frameworks that are based on Reflection such as Struts, Spring,
Hibernate etc? Or have your own Reflection code?
Someone else has reported a similar problem:
http://mail-archives.apache.org/mod_mbox/tomcat-users/200411.mbox/%3C5684A7E6FB10504393A2806C1F4C021003B0E725@orion.qas.com%3E
Did you debug your app to see where this error could be occurring?
After debugging your app, if you think it's a Tomcat error you could report
a bug here:
http://tomcat.apache.org/bugreport.html
