What does BlazeDS Livecycle Data Services do, that something like PyAMF or RubyAMF not do?

Question

I\'m doing a tech review and looking at AMF integration with various backends (Rails, Python, Grails etc).

Lots of options are out there, question is, what do the Ad

Answer 1

Adobe has two products: Livecycle Data Services ES (LCDS) and BlazeDS. BlazeDS contains a subset of LCDS features and was made open source. Unfortunately NIO channels (RTMP NIO/HTTP) and the DataManagement features are implemented only in LCDS, not BlazeDS.

BlazeDS can be used only to integrate Flex with Java backend. It offers not only remoting services using AMF serialization (as RubyAMF) but also messaging and collaboration features - take a look at this link (http://livedocs.adobe.com/blazeds/1/blazeds_devguide/help.html?content=lcoverview_3.html). Also I suppose that the support is better compared with RubyAMF/pyAMF.

If your backend is JAVA and you want to use only a free product you can also use GraniteDS or WebORB (BlazeDS competitors)
