When it comes to using AEM JEE with AEM Adaptive forms, we have to ensure that all Adaptive form variables are mapped to the JEE processes correctly.
The AEM variables are outlined in the “Guide LiveCycle Process Locator and Invoker” bundle which can be viewed by navigating to your AEM instance’s Configuration Manager: http:<server>:<port>/system/console/configMgr

The variables are:
- dataxml : contains forms data
- fileAttachmentsList : List of file attachments submitted as part of the form submission
- documentOfRecord : flat PDF version of the form if setup on the AEM Adaptive form
Once the variables are mapped correctly in AEM JEE process, the data flows seamlessly between Adaptive forms and the JEE processes.

Feel free to reach out if you have any questions.
