When you create extensions to Oracle E-Business Suite OA Framework pages, you must use the version of Oracle JDeveloper shipped by the Oracle E-Business Suite product team.
The version of Oracle JDeveloper is specific to the Oracle E-Business Suite Applications Technology patch level, so there is a new version of Oracle JDeveloper with each new release of the Oracle E-Business Suite Applications Technology patchset.
The Oracle Applications (OA) Extensions for JDeveloper 10g are now available for E-Business Suite Release 12.2.4. For details, see:
The same Note also lists the latest OA Extension updates for EBS 11i, 12.0, 12.1, as well as 12.2.
