A class called AMFConnection is available in BlazeDS from build 3.1.0.2602, written by Mete Atamel, one of the engineers working on BlazeDS. The basic purpose of this class is to allow a Java application to talk to a remoting destination. It can serialize/deserialize AMF messages using the BlazeDS classes.

Here is the spec : link text

I hope this helps.
