Issue with EBS–APEX Integration (Redirects to EBS Login Instead of APEX App)

Chandler BingSep 2 2025

I am working on integrating Oracle E-Business Suite (12.2) with Oracle APEX, following the document “Enabling Natural Language Query of Oracle E-Business Suite Release 12.2, Leveraging OCI Generative AI”.

I have completed all the setup steps, but I am facing the following issue:

  • When I click on the APEX menu entry in EBS, instead of opening the APEX application, it redirects me back to the EBS login page.
  • This leads to a nested login screen loop.
  • On the APEX side, authentication is created using the apps.fnd_apex.authentication function.
  • It seems that the EBS session is not being shared with APEX, but I cannot figure out why.

Has anyone faced this issue before? Could you please guide me on where to check or what might be causing this session/authentication problem?
