Hi, Chris, the auto-detection mechanism isn’t perfect and yes, it prefers Java EE over Jakarta EE 9. If you want to force deploying the application as a Jakarta EE 9 app, you can define the fish.payara.deployment.transform.namespace system property on the Payara Server and set it to true. See the documentation here: https://docs.payara.fish/community/docs/documentation/payara-server/system-properties.html
