Hello, I have problem calling my defined functions inside a module, while all other methods are called as you can see from out, I cant call “ping” method. Here is a part of java code : … public void ping(IClient client, RequestFunction function, AMFDataList params) { getLogger().info( client.getClientId() + “: [Custom module] ping”); sendResult(client, params, “pong”); } public void onAppStart(IApplicationInstance appInstance) { getLogger().info("[Custom module] onAppStart "); } public void onAppStop(IApplicationInstance appInstance) { getLogger().info("[Custom module] onAppStop "); } public void onConnect(IClient client, RequestFunction function, AMFDataList params) { getLogger().info("[Custom module] onConnect: " + client.getClientId()); } … Here is the console output: INFO server comment - [Custom module] onAppStart INFO application app-start _definst_ vod/_definst_ INFO session connect-pending 127.0.0.1 - INFO server comment - [Custom module] onConnect: 76184548 INFO session connect 127.0.0.1 - INFO server comment - [Custom module] onConnectAccept: 76184548 INFO server comment - [Custom module] onStreamCreate: 1 INFO stream create - - WARN server comment - Missing function: ping INFO stream destroy - - INFO session disconnect 76184548 - INFO server comment - [Custom module] onDisconnect: 76184548 Anyone have any idea what the problem might be ? (I rechecked config file and doesnt seem to be any problem there). Thanks for your help ---

I think the problem is that “ping” exists already. It is a method of IClient. ```auto public int ping(IModulePingResult pingResult) ``` Richard ---

Usually means that the Module is not references in the Application.xml or the jar file is not in lib. But you have are calling other functions in this module? Richard ---

You are compiling this in Wowza IDE? Does this file exist?: [wowza-install-dir]/lib/YourProjectName.jar What is the package path and name of the Module? Show the Application.xml Richard ---

First, my earlier idea is wrong, there is no problem with the function name “ping”. Sorry for the mislead. Your problem is something simple, a typo maybe, wrong package path, or wrong location of Application.xml Here’s a very minimal example: ```auto package com.wowza.wms.example.module; import com.wowza.wms.amf.*; import com.wowza.wms.application.*; import com.wowza.wms.client.*; import com.wowza.wms.module.*; import com.wowza.wms.request.*; public class ModulePingExample extends ModuleBase { public void ping(IClient client, RequestFunction function, AMFDataList params) { getLogger().info("ping"); } } ``` The Application.xml Module: ```auto Ping ping com.wowza.wms.example.module.ModulePingExample ``` Client-side call: ```auto netconnection.call("ping",null); ``` Check everything over. Check the location of the Application.xml. Should be: / **conf** /[pingApp]/Application.xml Check the connection: rtmp://[wowza-address]/[pingApp] Richard ---

public void pingCustom(IClient client, RequestFunction function, AMFDataList params) { getLogger().info( client.getClientId() + “: [Custom module] ping”); sendResult(client, params, “pong”); } INFO server comment - [Custom module] onConnect: 1200403944 INFO session connect 127.0.0.1 - INFO server comment - [Custom module] onConnectAccept: 1200403944 INFO server comment - [Custom module] onStreamCreate: 1 INFO stream create - - WARN server comment - Missing function: pingCustom still getting the same error, and dont have any clue why would it happen. ---

all those [custom module] calls are in the same module, and I rechecked Application.xml in my conf/app folder. The problem is while all the “predefined” methods are working like a charm the only method I wrote inside the module gives a “missing function” warning and does’nt work. I am pretty much confused about this. The thing I suspect is there are other classes (Modules extends from ModuleBase) in jar file, but I only gave reference to this specific Dummy Module. I am gonna start a new empty project and give it another try. ---
