Have you configured the server to support jmx remoting? Usually errors dealing with the RMI stub are due to jmx remote configuration issues. How are you starting weblogic? There should be a few env vars set in the startup script for weblogic that allow remote connections through the jmx protocol. Have you configured these?

Just an FYI: Most people check weblogic with wlsagent:

EDIT: I edited the thread subject so as to better reflect the nature of the question. I presume this may have been split off from another thread but it retained the old subject.

Hi,

Please let me know the which parameters required to configure as part of weblogic and also specify the environment variables need to set in the startup script of weblogic. Please help me to support nagios for weblogic environment.

Regards,
Siva

Did you read through the doc that abrist posted? It should be all you need for setting up wlsagent to check a weblogic installation.
