you should be able to receive your object parameters on Server side of RED5 like this

public void updateObjectData(Object[] params)
{
boolean firstVaraible = (Boolean)params[0];
String secondVariable =  (String)params[1];
} 

Hello! Thanks for the response. However, I am not actually receiving those as parameters. Instead, the only thing I get on the java server is:

params[0] = org.red5.core.ObjectTypee@1a76be4

When I try casting any of the parameters to strings or boolean or ints, they throw errors obviously. Below is my class in java, and I will then show you my class in AS3. They are of type LobbyType. Thank you so much for you help on this thus far, I have been stuck on this for so long!

This is the error I get from the server:

[ERROR] [NioProcessor-1] org.red5.server.service.ServiceInvoker - Error executing call: Service: null Method: updateObjectData Num Params: 1 0: org.red5.core.LobbyType@18fad4b
[ERROR] [NioProcessor-1] org.red5.server.service.ServiceInvoker - Service invocation error
java.lang.reflect.InvocationTargetException: null

it seems you are not parsing the object the right way , if you want to get parameters out of your object you need to use
param0= org.red5.core.ObjectTypee@1a76be4[0]
param1 = org.red5.core.ObjectTypee@1a76be4[1]

it might also be possible that ObjectTypee@1a76be4[0] is also object further so casting wont work. try ObjectTypee@1a76be4[0][0] also.

org.red5.core.LobbyType@18fad4b is a class org.red5.core.LobbyType, If I am right ? I don't think you can send a class to server side and then extract its properties. Only objects are supported. You can cast the Object org.red5.core.LobbyType@18fad4b to class LobbyType and then you might be able to access the properties.

you mentioned that you are making call (nc.call("updateObjectData",null, myObject);) from actionscript but I cant see any call used in the code you posted.

I am so sorry for the confusion. I was using 'ObjectType' as an example, but my actual object is 'LobbyType'.

@Indier - You are correct. I am currently trying to cast the object to type LobbyType, but it is not working. Below I will demonstrate exactly what is happening:

1) The client code on AS3 has created an object called testObject and is of type LobbyType. It makes a call through the net connection using the following:

public function sendSomething():void
{
testObject = o as LobbyType;
// setters omitted to save space, I just filled the object with random data
testObject.registerObject();
ncLobby.call("updateLobbyType",null, testObject);
}

2) The red5 server successfully receives a net connection call to the following function:

ps: I used the getClass() function to show that it does in fact belong to type LobbyType

public void updateLobbyType(Object params)
{
LobbyType temp = new LobbyType();
System.out.println("It is: " + params.getClass().toString());

// It is: org.red5.core.LobbyType
}

It should be noted that I have tried implementing Rayan's idea by casting the object but to no avail...

public void updateLobbyType(Object params)
{
LobbyType temp = new LobbyType();
params.getClass().cast(temp);
System.out.println("It is: " + temp.getUid()); // getUid() is just a getter in the class

// It is: org.red5.core.LobbyType@11da1d1
}

But it doesn't seem to allow me to access any of the member values. I have also tried what you mentioned by doing:

public void updateLobbyType(Object[] params)
{

LobbyType temp = new LobbyType();    	
 	String red5User = (String) params[0];
    	int uid=Integer.parseInt(params[1].toString());
    	String fname = (String) params[2];
    	String pic = (String) params[3];
    	Boolean inttbl = (Boolean) params[4];
    	int t=Integer.parseInt(params[5].toString());
    	int s=Integer.parseInt(params[6].toString());
}

but only params[0] contains data which is just 'org.red5.core.LobbyType@11da1d1', the other objects in the array do not exist. I guess my question is how do I send an object from AS3 to the Java server and access the members of that object class??

I got it! There was two things that I did.

1) I removed the IExternalizable function because I am only sending simple data types, I figured I would remove that..

2) After doing that, I went back to how I originally wrote the function which was like this and it worked:

public void updateLobbyChat(LobbyType params)
{
someStringType = params.getFname();
}

Thanks again for all your help. It is so awesome to think complete strangers are willing to help others. :)

Hi john, As far as I know sending anything other than simple data types is not supported by AMF (ActionScript Media Format). I have not tried it with RED5 but I have tried something similar to this in one of my FMS Application. I tried to send bitmap object (byte Stream Object to server) through server call by passing as parameter. The server will receive the Object but the actual type is lost. So finally after lot of study I found that Flash when communicating with server side cannot send or receive complex data types, like class , Bitmap data, Array collection etc.

When you pass a class from client its very unlikely that its members can be accessed from server and that too in java because its as3 class. How ever I will try to find if anything similar could be found and will post you back. Please do share if you found any solution to you problem.

cool this is great. you are welcome, Knowledge is for sharing and we gain always by sharing it. Like I just Gained :)
