If your Express Server is running but you do not see your catalogs, make sure your copy of Express Server is licensed. Licensing information is listed below the server status information. For more information see Licensing.
If your Express Server is running and your license is valid but you still cannot see your catalogs, open and examine the Error log and other log files listed below the server and license status information. For more information see Accessing and Using Log Files. You can also open these log files manually. By default they are located in the directory <Express Server installation directory>/ImageServer/var/log,
If problems with the catalog configuration file are reported, examine the file "catalogs.xml" and look for missing brackets, bad path names or any other errors.
If errors creating image or item objects are reported, run the following script to diagnose potential problems:
ImageServer/modules/regall.bat (Windows)
ImageServer/modules/regall.sh (Unix)
