ORDS, SODA & JSON in the Database

I'm trying to install ORDS with Tomcat in a container deployment to OpenShift but getting an error about the ords.war file being corrupt.

ORDS version: 24.4.0.345.1601.

Tomcat version: 9.0.105.

Java version: openjdk 21.0.7 2025-04-15 LTS.

These versions appear compatible, according to the installation checklist, although Tomcat images are only built with Temurin or Corretto Java and this has not been a problem with previous versions of ORDS (<22). https://docs.oracle.com/en/database/oracle/oracle-rest-data-services/24.4/ordig/installing-REST-data-services.html

Truncated Dockerfile, to show the commands causing the error:

Error: Invalid or corrupt jarfile /u01/ords/ords.war

What does that even mean? I can open the ords.war file in 7-Zip, so it does not appear to be corrupt.

ORDS 24.4 was downloaded from https://www.oracle.com/technologies/appdev/rest-data-services-downloads-244.html

I can see there is a My Oracle Support article that covers this error for ORDS 24 but or team is not associated with a support identifier to read it: https://support.oracle.com/knowledge/Middleware/3063870_1.html.

The --verbose flag doesn't seem to do anything? How else can we debug this?

Thanks.
