Primary Note for ActionLookupFailedException Occurring in WebLogic Portal (WLP) Environment
(Doc ID 1447577.1)
Last updated on APRIL 16, 2021
Oracle WebLogic Portal - Version 9.2.0 and later Information in this document applies to any platform.
This Primary Note addresses the ActionLookupFailedException that sometimes occurs while running a WebLogic Portal (WLP) Application. The exception is unrecoverable and normally requires a reboot of the server(s). In some cases the exception may still exist even after rebooting the server(s).
Although the ActionLookupFailedException manifests itself during run-time of a WLP Application, normally inside of a pageflow portlet, the underlying root cause of the exception may be a WLP, WebLogic Server (WLS), WebLogic Workshop (WLW) or Oracle Enterprise Pack for Eclipse (OEPE) issue. There are various causes to this issue. The ActionLookupFailedException is a generic wrapper exception so all ActionLookupFailedException issues are not the same. It happens in a variety of different ways within WLP applications and has been observed across all WLP versions.
Note: Some of the patches referenced in this document that resolve the ActionLookupFailedException are not WLP patches, but WLS, WLW and OEPE patches.
This Primary Note is set up in the following format. Since there are different ActionLookupFailedException issues that all have a unique symptom, cause and solution, each known issue will be listed separately with its own Symptom, Cause and Solution. If you are encountering an ActionLookupFailedException issue that is not resolved by any of the patches mentioned in this note then you might be running into an unknown issue for which a new root cause analysis must be performed by Oracle Support. In this case please open a Service Request with Oracle Support.
Note: A few key points about applying the recommended patches:
After applying any of the recommended patches below make sure you clear the server caches to ensure there are no conflicts between the original and patched libraries. Please see the Clearing Server Caches section at the end of this document.
When searching for patches from the MOS Patch Download page, if you use the bug number you do not need to know the product, it will find the patch and display the bug number. It is therefore easier to just search by bug number. However, if you do not use the bug number but instead use the patch ID to search for the bug then you'll need to select the correct product when searching for the patch. All patches in this document will list the product (WLP/WLS/WLW/OEPE) the patch is for.
