Symptoms

In Oracle Financial Services Data Integration Hub (DIH) 8.0.x, for an environment with Weblogic, the Connectors screen is not opening.  It shows the progress bar continuously.  Also, the connectors are not listed on the Publish/Unpublish screen.

The following error exists in the web layer DIH.log:
