Steps to Reproduce



Start the is-web from the WebLogic console


Root Cause



The cdm.vbd.url in the database has a "null" value, which prevents the application from starting up.
This can be verified by executing the following SQL query:
select * from IS_VBD_CONFIGURATION


Resolution



The issue is resolved through the following local change:
Change the value of the cdm.vbd.url in the database to "/vbd" (without quotes), commit, then restart the server.
