You’d think this would be a bad file error, but it wasn’t. Turned out the portalDataSource connection pool had gone bad, preventing the desktop from being found or loaded. Again, you’d think that a restart of the server would fix that, but it didn’t. I had to un-deploy and re-deploy the connection pool before things started working again.
This was on WebLogic Portal 10.3.2. I haven’t seen it before, but that doesn’t necessarily mean it is restricted to that version.
