I have try wowza module, but i have one question. That is why I can’t use my custom module.

I have already add .jar to lib folder and add the config to the [Wowza]/conf/[Application]/Application.xml file.

And I have been checked that i was not type wrong and restart server.

Hi,

Have you restarted Wowza after adding the file to the Wowza /lib directory? If so and it’s still not working then check that the class path matches what you’ve set in Wowza - e.g. by doing unzip -l [jarfile]

Regards,

Paul

Hi Arun,  
Make sure that your jar file exists in the [wowzaInstallDir]/lib/ folder and has the correct permissions. Use the fully qualified name in the module class parameter (packageName+className). Restart your Wowza server after making any changes to the package/class.
