Hi !! 
 
I am accessing custom mbeans of was 6.1 from my jmx client. 
I have 2 JREs to run this jmx client either from the 
A) WAS JRE 
B) SUN JRE 
 
If I run my jmx client with sun jre 5.x I am only able to access 
but can not modify the mbeans of WAS. 
 
this client is able to connect to was 6.1. 
No run time error is coming. 
Only the code used for accessing the mbeans are not executing.

Is there anything in the WAS logs?

BTW, if an error is thrown, your code will simply ignore it. You
probably need to put something in the catch() clause.

Looks like the call to getMBeanInfo is failing. You might ask in a Sun
JVM newsgroup.

According to this, it sounds like you need to use the IBM ORB in the SUN JRE, if you need to use the SUN JRE:
