Hi.

I was installed wowza streaming engine(developer license) inside docker container.

And wrote java code exactly same with this page [https://www.wowza.com/docs/how-to-use-imediastreamactionnotify3-interface-to-listen-for-rtmp-stream-events-includes-codec-info](https://www.wowza.com/docs/how-to-use-imediastreamactionnotify3-interface-to-listen-for-rtmp-stream-events-includes-codec-info).

And Use export function of Eclipse, made .jar file. and copy to (install dir)/lib/\*.jar

and restart wowza streaming engine, GoCoder connected with wowza streaming engine.

But, I can’t checking processing or not.

In example, System.out.println(~~~). Maybe, result of this function will be showing to docker logs.

What is wrong in my process…

Answer please.

Thank you.
