Falied to load resource files of Oracle APEX plugin

Question

I've installed a plugin in APEX, but when I've tried to use it on a page, I've got some nasty errors and page not working properly.

The files are present in the plugin settings:

But, as you can see below, they are not being loaded for some reason. I get 404 errors instead.

I have ORDS running and APEX 19 installed on DB 19c XE.

What could be causing this? Wrong ORDS configuration maybe? How to fix it?

Answer 1

After APEX upgrade from one version to another you should recompile i.war by running java -jar ords.war validate --database apex. java -jar ords.war static could also be useful.

For debug it is convinient to edit ORDS config file defaults.xml with these strings:

<entry key="debug.debugger">true</entry>
<entry key="debug.printDebugToScreen">true</entry>

Don't forget to set them false on production.

Answer 2

I had the same problem. I checked the APEX and ORDS accounts, their passwords had expired. Once I fixed that, the problem was solved.
