Receive AS3 objects in Java through sockets

[OmniNL]

How do i deserialize AMF data in Java that comes through a socket?

(I use Flash ide)

[OmniNL]

Nobody? This problem is keeping me busy for a week now. Getting desperate.

Ive read alot of pages but they all leave out the info that i seek!
for example: link

They leave out the part how they receive the data sent to java. which stream to use etc.. getting crazy.

I'm sure someone can help you here; I could, but I don't have any time to write any sort of explanation and won't for a while.

AS3 and Java both support (either natively or through some library) numerous forms of serialization. For example, SOAP, AMF, and JSON (although it's not really the same as serialization) can all be used to some extent to transfer objects between Java and Flash.

I know about the serialization part, i use AMF. I just don't know how receive them in Java and then edit them. Using:

PHP Code:

new BufferedReader(new InputStreamReader(socket.getInputStream())); 


Gives me the string, i can send it back just fine but i want to edit some variables server side and then send it back, it doesn't work that way though since then the serialization gets corrupted or something. (flash reads the input as undefined)

Say im sending 2 strings in flash (keeping it very simple, there is more to send)

PHP Code:

socket.writeInt( user_ID );
socket.writeUTFBytes( message ); 


Then i want to be able to access those 2 variables in Java, edit the message, keep the user_ID. And send it back to Flash.

So all i need to know is how to read the socket stream in java to be able to read/edit the variables

When I was talking about serialization support, I was also (implicitly) talking about deserialization, which is what you're having trouble with. Java's default object (de)serialization doesn't use AMF; that's why you're getting errors. You need to use some library (like BlazeDS) that knows how to handle AMF.

Ah thanks for giving me a direction, ill check it out
Edit: I use Adobe Flash CS4 and not flex, And BlazeDS seems to be only for flex. Can i still use it?

EDIT2: I read you need a servlet container or something like tomcat? Is this true?

You could embed jety or tomcat in your application and use as a servlet container. http://docs.codehaus.org/display/JETTY/Embedding+Jetty http://lacson.name/archives/2004/12/..._embed_to.html

Here's the specification for AMF should you fancy writing your own AMF (de)serializer:

I know that Zend Framework has a PHP AMF server -- you could look at how they do it.

Ah thanks, i shall read that when i have the time. I actually gave up trying but this should blow some new life in my projects again
