Symptoms

In Oracle Financial Services Analytical Applications (OFSAA), when you try to create an Excel-Entity Mapping, the screen where Excel spreadsheet data should appear never loads and remains empty.  You go to Excel Upload > Excel-Entity Mappings and click on the "Add" button.  You enter a Mapping name and Description and then select an Excel file.  When you click on the "Arrow" button, nothing happens.  The data from the Excel spreadsheet never loads.

If using Tomcat, the following error appears in the Tomcat server's catalina.out file:

DEBUG - Returning ssh-rsa

If using Weblogic, the error is slightly different:

DEBUG - Returning ssh-rsa
