I’ve tried a variety of modules and keep getting errors like this:

```auto
loadModFunctions[live/_definst_]: Module class not found or could not be loaded. Check [install-dir]/conf/live/Application.xml to be sure all Modules/Module/Class paths are correct: name:ModuleAVMix class:com.wowza.wms.plugin.avmix.ModuleAVMix

```

At first I tried creating my own in Eclipse, but when that didn’t work I went here to try some that were already compiled: [https://www.wowza.com/docs/utility-modules-for-wowza-streaming-engine-media-server-software](https://www.wowza.com/docs/utility-modules-for-wowza-streaming-engine-media-server-software).

All of the errors are the same. I uploaded the jar into the /lib folder of the Wowza installation.

Could it be that I am running the AWS hosted version or one with a developer trial key?

Not quite sure what else it could be at this point.

Restarting the entire server, not just the application did the trick.

Hi,

It does just seem to suggest that the module is not there or the module has a different class name (was it recompiled or rebuilt from the example provided [here](https://www.wowza.com/docs/how-to-start-and-stop-live-stream-recordings-programmatically-livestreamrecordautorecord-example%28LiveStreamRecordAutoRecord-example%29))?

It would be easiest to troubleshoot this via a ticket. Please open a [support ticket](https://www.wowza.com/support/open-ticket) and include a zip of your /conf and /logs plus the jar file for this module, plus any source if it has changed, and we can take a closer look.

Regards,

Paul

Hi,

I am seeing this error in the wowzastreamingengine\_error.log

loadModFunctions[MyAxisCamera/_definst_]: Module class not found or could not be loaded. Check [install-dir]/conf/MyAxisCamera/Application.xml to be sure all Modules/Module/Class paths are correct: name:ModuleAutoRecordAdvancedExample class:com.wowza.wms.plugin.livestreamrecord.module.ModuleAutoRecordAdvancedExample

I have restarted the Wowza Server. I have restarted the stream, and restarted the mac where I have Wowza installed. All the permissions, owner on the jar are the same as other jar in the install-dir/lib

I am adding my Application.xml

I’m now running into this issue as well. Any resolution? I have the trial version.
