Hello
Malcolm and Geoff, thanks for your advices.
After a few failed attempts I did as you suggested, and now, flash-client is
able to communicate via XML-RPC with Tapestry.
I took the the ActionLink-Component and ActionService as base, sticked all
the URL-serviceContext (which is expected from my ActionService-derivate)
into the flash client request, added the flash-request-evaluation and
method-invocation to the service and thats'it !!!
This appoach did not work with Flash-Remoting, which Macromedia sells for $
1000 per CPU and which works different than XML-RPC and seems only to be
useful for pure flash applications.
If there is interest, I can povide details.
I will put some of my stuff on sourceforge soon, then maybe, if Howard likes
that kind of flash-interoperabbility, the flashService and the
FlashComponent could be added to the mainstream build, its just a few lines
of code, the Apache XML-RPC-jar is also very small (on the other hand, I
don't like blown-up frameworks, if I do not need the particular feature)
regards
Roberto
