Applies to:

Oracle Internet Directory - Version 11.1.1 and later
Information in this document applies to any platform.

Symptoms

Unable to access Oracle Services Directory Manager (ODSM) website from wls_ods1 WebLogic (WLS) Managed Server listening on default port 7005.

ODSM does not render. Seeing a spinning icon and page does not render. Or getting a blank screen while accessing ODSM. It gives the impression that page is loading but it never comes back up.

The WLS Managed Server log originally shows:

<Error> <oracle.adfinternal.controller.application.AdfcExceptionHandler> <ADFC-50018> <ADFc: No exception handler was found for an application exception.


Cleaned out files under tmp directories as per Document 1900379.1, but same problem continues.

Also tried redeploying the odsm.ear file.

Afterwards, the log error shown is:

<Watch 'UncheckedException' with severity 'Notice' on server 'wls_ods1' has triggered at Jun 24, 2016 2:05:52 PM CDT. Notification details:
