This kind of error indicates the compiled jar file is not in the lib/ folder of your Wowza Streaming Engine install, or possibly anything it may rely on to work correctly.

What I would do is strip down the module to a bare minimum and get that working then add back any code to see if/how/when it fails.

Thanks for answer!

the jar 100% is in lib folder! And some time it working

I think may be it from asynhron calls… the code is very simple

package com.wowza.wms.example;
import com.wowza.wms.httpstreamer.model.IHTTPStreamerSession;
import com.wowza.wms.module.*;
import com.wowza.wms.application.*;
public class ModuleAccessControlHTTPStreaming extends ModuleBase
{
	public void onHTTPSessionCreate(IHTTPStreamerSession httpSession)
	{
		boolean isGood = true;
		String ipAddressClient = "";
		String ipAddressServer = "";
		String queryStr = "";
		String referrer = "";
		String cookieStr= "";
		String userAgent= "";		
		
try {	
  	        userAgent = httpSession.getUserAgent();    
	        ipAddressClient = httpSession.getIpAddress();
		queryStr = httpSession.getQueryStr();
		referrer = httpSession.getReferrer();
		cookieStr = httpSession.getCookieStr();		
		ipAddressServer = httpSession.getServerIp();
			
        final String YYY = "xxx";
        referrer = referrer.trim();
        String[] array = {"ForkPlayer", "Chrome", "LibVLC","MXPlayer","Winamp"};
      
        
        if (referrer != null && !referrer.isEmpty()) {
            isGood = checkReferrer(referrer, YYY);
	    if(!isGood){
            isGood = checkReferrer(referrer, "zzzzzzzzz.zz");}
            if(!isGood){
                isGood = checkReferrer(referrer, "xxxxxxx");}
            if(!isGood){
            isGood = referrer.contains("xxxxxx"); 
            } 
           
        } else if (userAgent != null && !userAgent.isEmpty()) {
            if (checkReferrerArray(userAgent, array)) {
                isGood = false;
            }
        }
        
             
		if (!isGood) {
			 httpSession.redirectSession("http://xxx.xxx.xxx.xxx:xxxx/vod/mp4:BUY_ITV.mp4/playlist.m3u8");
		       }
        
		}catch (Exception e) { 
			getLogger().info("Errorr!!! accept:"+isGood+" ipAddressClient:"+ipAddressClient+" queryStr:"+queryStr+" referrer:"+referrer+"	useragent:"+userAgent);
			httpSession.redirectSession("http://xxx.xxx.xxx.xxx:xxxx/vod/mp4:BUY_ITV.mp4/playlist.m3u8");			
			
		}
        finally  
		{
			getLogger().info("EModuleAccessControlHTTPStreaming.onHTTPSessionCreate[ ]: accept:"+isGood+" ipAddressClient:"+ipAddressClient+" queryStr:"+queryStr+" referrer:"+referrer+"	useragent:"+userAgent);		
		}
		
				
	}     
    
    private static boolean checkReferrer(String whom, String withWhom) {
        return whom.contains(withWhom);
    }
    private static boolean checkReferrerArray(String referrer, String[] parameters) {
        for (String item : parameters) {
            if (referrer.contains(item)) {
                return true;
            }
        }
        return false;
    }

Have you added the VM Arguments to your IDE?

In Eclipse, right click on the project in the left menu and choose “properties”

Next, click on the Run/Debug settings on the left, highlight the launch configuration and click Edit

Under the “arguments” tab, add the following line to the output in “VM Arguments”

On Windows:

-Dcom.wowza.wms.native.base="win"

On Mac:

-Dcom.wowza.wms.native.base="osx"

Hi ,

This may be caused due to Exception declaration in onHTTPSessionCreate. I think after the removal of exception it will work.
