Action Message Format (AMF) is a binary format used to serialize object graphs such as Adobe Systems published the AMF binary data protocol specification in December and announced that it will support the developer community to . Adobe open-sourced their FDS (Flex Data Services) product today, and along with it published the AMF3 spec (this time without NDA!). FDS.

Support for AMF Protocol | LoadComplete Documentation
Currently I’m propably simply going to use wireshark and the BlazeDS code to somehow reverse-engineer a Protocol description for me, but I don’t know why not a single valid spec is availble.
Fortunately I managed to find out how the protocol works. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed.
If you’re using Flex RemoteObject, there are some additional wrapper objects that Flex uses in the messaging. AcknowledgeMessageExt As for other objects implementing the IExternalizable interface, LoadComplete does not parse them and does not support modifying data in them. Then I came across this gem:. This is the way the web server codes protocol version and data types in AMF anf3. But then I came across this: Articles needing additional references amf December All articles needing additional references.
I tried other charsets and each one would change some range of bytes. Target URI – the name of the method that must be used on the client side to handle an appropriate response. As someone who has built a library that can parse AMF and make RPC calls RocketAMF a,f3, I would advise that you use one of the existing libraries rather than write your own if you just need remoting support.
The parameter type and the protocol version in which this type is defined declaration of some types can be different in different protocol versions. Below is a brief description of the service parameters received from the server:. Header name – the remote operation or header name that will be used to handle an appropriate header.
Values can be of any type including other objects and whole object graphs can aamf3 serialized in this way. It is not necessary aamf3 install spdc new classes!
The format is often used in conjunction with Adobe’s RTMP to establish connections and control commands for the delivery of streaming media. This page was last edited on 1 Octoberat Well on the one side I simply wanted to understand the protocol. If there are several such parameters on the same tree level, they are reported as Unnamed 2Unnamed 3 and so on.
Applies to LoadComplete 4. This page is no longer in use. Before I get into the gory details of how this works, check out some developer eye candy: Here one can see an array in turquoise as a value of the ‘data’ key which has one member. XML is supported as a native type. I used one from adamia.
This may be another point that trips people up at first when looking at basic AMF serialization versus NetConnection based communication. If a parameter of the String type is empty, LoadComplete will not display anything in the cell.
LoadComplete does not change the request structure. In the latest releases there is an int and a uint which are included in AMF3 as separate types.
LoadComplete obtains the parameter name from the AMF stream. Amr3 path to the parameter in the parameter tree, starting from the root element. Response URI – the name of the operation that will be used to match the response to the client invocation. But there was a problem.

LoadComplete supports only some of these objects, namely:. ArrayList DSK shorthand version of flex. For more information on the parameters described above, refer to the Adobe web site. The information contained on the page should NOT be seen as relevant or reliable. Unfortunately both don’t specify the actual message format Header, Body, I am trying to create an adapter that specc on J2ME Byte arrays, whose size exceeds 50 bytes, are displayed as strings.
The entire procedure is very simple:.
