Oracle Applications (12.1.3) not cooperating

I am trying to use basic automations on an Oracle Applications that I open from a link within a browser. I am able to sign in (browser based), and when the Java application opens, I am able to shift focus to that application window.

However, when trying to replicate any user action (click, type into, set text), no matter how I do it, nothing happens. When using recorders or UI Explorer, all I can select is the entire Java application window - I am NOT able to select individual user interface elements.

I have installede the Java extensions in UI Path Studio, but it doesn’t help much.

Any ideas or experiences??
