While on a clustered environment running wildfly 8.2.1 with mod_JK, when trying to View users, groups, organizations, etc. you receive the following error 



12.6 SP6 or SP7 
Wildfly 8.2.1


1)This error is displayed on the UI due to the version of mod_JK that is being used.

2)configuration errors inside files. 


1) please upgrade the version of mod_JK you are using. If the version is out dated this will cause the error displayed above. A working version of mod_JK that works with wildfly 8.2.1 is 1.2.40. 

2) Update the worker.worker1 to match the node_name on the standalone.bat file.

On the standalone.bat file it will say "set "NODE_NAME=iamnode0"" copy the node_name and replace worker1 with the node name to look like worker.iamnode0. 


Afterwards restarts the clustered environment and the issue should no longer be present.
