we're upgrading from CF10 to CF2021 (not married to 2021, coudl revert) but have a legacy air app that leverages AMF/flex2gateway. I'm 99% sure this is the flex remoting feature listed as retired https://helpx.adobe.com/coldfusion/deprecated-features.html but wondering if it MAY be the "flex integration" listed as removed. 2 questions: 1. does anyone know what these features are or where they are described (Google has failed me) so i can know which one i need for flex2gateway 2. does anyone know of a doc/article that describes how to unretire flex2gateway in recent CF versions?

IF it's still there, you'd likely need to re-add the web.xml servlet mappings.

yeah i can def try to hack it, i was more looking for the official docs

I don't know that it's "hacking it" per se. I assume any official docs are just going to tell you to uncomment stuff as well. I just don't know where any official docs would be. I'd say this is a great question for @priyank_adobe or @Mark Takata (Adobe) to help out with 🙂

taking hacks at parts of the problem till you knock it down is hacking it

Right, which is why I told you to go look in that file. The web.xml has historically had comment blocks explaining certain functionality that may be off by default. I figured it would be a good starting place.

ah, didn't realize you were saying theird be comment blocks with direction. i went through web.xml but didnt' see anything re remoting or integration . only mention of flex was CF Monitoring filter mappings

Got it, well it was worth a look. perhaps it's 100% gone now? Hopefully Priyank or Mark can shed some light. There's a not many people still using them these days.

yeah that's what part 1 was about. it says flex integratoion is removed, but flex remoting is just retired. i'm not even sure which one AMF really falls under...i thought it was remoting
