500 Internal Server Error : When Using ORDS 3.x and URL Mapping (Doc ID 2060089.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Application Express (formerly HTML DB) - Version 4.2 and later
Oracle REST Data Services - Version 3.0.1 and later
Information in this document applies to any platform.


Oracle REST Data Services (ORDS) has been set up to have an additional database connect using the URL Mapping feature. In trying to access the new URL Mapping, an "500 Internal Server Error" is given as shown in the following screenshot.

Furthermore, if ORDS is running standalone, then the following exception can be seen in the console window that started ORDS. 



Depending on which URL was accessed first, you could see the above Internal Server Error or a Spinning Browser wheel. That is, if the default APEX URL was accessed, then the Internal Server Error is shown. If after this you access the new mapped URL, you would see a browser with a spinning wheel.



 ORDS has been configured to have an additional database via URL Mapping as per the documentation.
