[Flash Islands] Flex communication, AMF (Action Message Format) ?

[guillaume-hrc]

Hi,

I was wondering how the communication between the Flex component and the server was handled (HTTPService, WebService, RemoteObject).

If it is through Remonting, is it using AMF (Action Message Format) which is supposed to reduce the size of network packets by 70% thanks to its binary format ?

-> Adobe offers tools (LC ou BlazeDS) for this

What about the same for the Web Dynpro ABAP.

Is there an ABAP -> AMF converter ?

Thanks in advance for feeding the debate.

Best regards,

Guillaume

Hi Guillaume,

I'm not sure whether I've got your question right, but if you are using FlashIslands, this means your Flash component is embedded in Web Dynpro, I assume, your FlashIsland doesn't communicate with the server at all, it communicates with Web Dynpro.

kind regards

Hi Stefanie,

Thanks for your answer and sorry for the delay.

I put a bit more of thought into this and if the Web Dynpro is performing this, does it mean :

- the Web Dynpro retains the context instead of the Flex component itself ?

- there is a round-trip with the server each time Flex needs to get new data ?

Thanks in advance.

Best regards,

Guillaume

Get the answers to these questions in the "Next Generation ABAP Development (2nd edition)" book, in pages 557-558 (§16.1.1)

Also, look at page 38 of this document:

Hi Guillaume,

in the meantime I've prepared a small example:

I hope this will explain a little bit the way it works!

Kind regards
