Sounds like there is an issue with the client-side sync method.

I don’t think you will be able to do that, because there are sharedObjects and the many to many audio/video streaming.

You could have an application where users watched a live video on one netconnection from edge servers, and synced with sharedObjects using another netconnection connected to a dedicated sharedObject server. But many to many chat, everyone has to connected to the same server, application and application instance per session.

If you connect like this, with a username:

```auto
netconnection.connect("rtmp://[wowza-address]:1935/[appName] "richard");

```

You can extract the username and attach it to the client in a property, like this:

```auto
package com.wowza.wms.example.module;
import com.wowza.wms.amf.*;
import com.wowza.wms.client.*;
import com.wowza.wms.module.*;
import com.wowza.wms.request.*;
public class ModuleTrackUserData extends ModuleBase {
	
	public void onConnect(IClient client, RequestFunction function,
			AMFDataList params) {
		getLogger().info("onConnect: " + client.getClientId());		
		String user = getParamString(params, PARAM1);
		client.getProperties().setProperty("username", user);
	}
	public void onConnectAccept(IClient client) {
		String username = client.getProperties().getPropertyStr("username");
		getLogger().info("onConnectAccept username: " + username + " ID: " + client.getClientId());
		
	}
}

```

Take a look at this Flex example that does that:

Oh, sorry, that’s the thread we are in. I’m not sure what to tell you. These are the examples we have. You have to work with this.

No, it’s not doing that. As you can see, the Flash interface has no input for username. On the server-side, clients are distinguished by clientid, the identifier generated by Wowza. You have to modify the Flash interface to accept a username, and the server-side to use it like the example I showed earlier.

The path has changed, but functionally TEA.as is the same. You just have to reconcile the path. You can change it in Flex if you are building the source. Or change it i TEA.as, change this to old path:

```auto
package com.wowza.encryptionAS3 {

```

And you have to change the folder structure to match.

This is a Flex (SDK 3.5) application. The source is [here](http://dotnet.lakesidetechnical.com/wowza/avchat/avchat.zip)

Flex (Flash Builder) uses text files with .as and .mxml extensions for source code. There is no .fla

You will have to learn how to use Flex.

Do you want a Flex developer to help with this? We have a list of independent consultants. Send email to support@wowza.com to request if you do.

Combining these two examples should be fairly easy.You could use two NetConnections if that makes it easier.

I appended clientID in that simple example to avoid name collisions or having a real authentication system. It’s a fairly accessible example, good starting place for Flex and Wowza.

This example includes a jar file that needs to be copied to Wowza /lib folder, then Wowza must be restarted.

If you running Wowza as a server, stop the service then run Wowza in stand-alone mode: /bin/startup.bat, so you can see Wowza log output while you test. It is very helpful.

Previous post was to wrong thread.

This is the issue:

> ERROR server comment - loadModFunctions: java.lang.ClassNotFoundException: com.w
> 
> owza.wms.example.module.AVChat

This means the jar is not in the Wowza lib folder or you didn’t restart Wowza after adding it.

You can ignore those Warnings. Or change to:

```auto
for (var p:Number = n-1; p >= 0; p--) 

```

Yes, it is at least 75% the VideoChat example that ships with Wowza. Please trace these functions to see what they do. It’s a starting place.

Try setting the project to use SDK 3.5 in the Project Properties, Actionscript Compiler tab.

There is a .jar file included with this example. Make sure you have have copied that to your Wowza /lib folder, and added the Module to the Application.xml, and re-started Wowza. Then each user should see the stream the other has published.
