Error Unable to fetch authentication_scheme

Question

I have imported a HTMLDB application into a new workspace.
When I try to run the application I get the error:
Error Unable to fetch authentication_scheme in application 100
I need to be able to use this application with other workspaces (the schemas are owned by different owners but are identical).
Please help ... Thank you, Rick

I don't know what APEX is?
What I have is one instance or SID called "smb"
I installed htmldb there.
I also have created 4 identical schemas there. (one for each of my developers)
I have created 4 htmldb workspaces (one for each schema).
I built the application (to edit some of the tables in the schema) in one of the workspaces.
All I want to do is get the application into the other workspaces so that the other developers can use it.
I used the export/import button at the application level to export the application:
File Format: UNIX
Owner Override: the schema of the new developer
Build Status Override: Run and Build Application
It created a file f114.sql
I then logged in to htmldb in the new workspace of the schema for the new developer.
I clicked on the "Create Application Button" then selected "From an Application Export File"; browsed for the exported file and opened it. This put its path in the Import File text box. I selected File Type: Application/Page Export.
I got:
The export file has been imported successfully. If you wish to use this file to install press Install:
I pressed Install and got:
Logged Into Workspace: KODIESMB1
Export File WorkspaceID: 633628732993759
Export File Application: 114
Export File Version: 2004.07.04
Export File Parse As Schema: KODIESMB1
Application Origin: This application was exported from another workspace.
Parse As Schema - Select Schema - KODIESMB1
Build Status - No Build Option - Run Application Only Run and Build Application
Install As Application Reuse Application ID 114 From Export File
Auto Assign New Application ID
Change Application ID
I pressed "Install Application" and got:
The application could not be installed because it already exists in different workspace. If you wish to install the application, please do the following:
Remove the existing application from the workspace it currently exists in.
OR
Change the application ID in your export file. An application ID that's currently available you can use is 101.
Upload the changed export file to the repository, and re-install your application.
It took me to the repository ... I selected the import and changed the ID to 101 and pressed install and got:
Application 101 installed
I pressed the Run button and got:
Error Unable to fetch authentication_scheme in application 101.
OK
I pressed OK and it took me back to the Post-App Install Utility Option.
I do not know what to do since I don't understand the Error?
Thanks,
Rick
