Description/symptom of problem:  
JR27104 resolves the following problem:

ERROR DESCRIPTION:                                              
There should be some checking to ensure that the                
deployment target where                                         
the Mbean is being called actually has a process/task container 
installed. Through WPS L3 investigation, the current problem    
with BPC is that when we try to stop a process through the admin
console, it cannot find "ProcessContainer" MBean in MBean       
registry.                                                       

LOCAL FIX:                                                      
N/A                                                             

PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server 6.0.2.x users.

PROBLEM DESCRIPTION:
When customers set up a WPS cluster
and install a http server on it.
They would be unable to stop business
process and human task from admin
console.

RECOMMENDATION:
None

BPC/HTM could not be stopped on cluster with http server.

PROBLEM CONCLUSION:                                             
This problem is related to WAS.webui.bpc component. During the  
stop action of business process or human task, WPS would look   
for "ProcessContainer" MBean on every server of cluster node.   
An error occurs as this MBean does not exist on web server.     
After installing this fix, it would first check the type of     
server so that it could stop buniness process or human task     
successfully.
