Help me i am not able to understand Wowza modules i studied but in public void onAppStart(IApplicationInstance appInstance) { // String fullname = appInstance.getApplication().getName() + “/” + appInstance.getName(); // String clients = appInstance.toString(); // int playstreamcount = appInstance.getPlayStreamCount(fullname); // String path = appInstance.getStreamKeyPath(); // String streamtype = appInstance.getStreamType(); // String datestartes = appInstance.getDateStarted(); // // getLogger().info("onAppStart:Shiv++Rama " + fullname + clients + playstreamcount + path + streamtype + datestartes); ``` appInstance.setMediaListProvider(new MyMediaListProvider()); } ``` i make jar file and configure in Application.xml MyStreamingRecording MyStreamingRecording com.myapp.digivive.MyStreamingRecording but its not working when i use content streaming in VLC and see the log files its shows \*_Module class not found or could not be loaded. Check [install-dir]/conf/vod/Application.xml to be sure all Modules/Module/Class paths are correct:_ MyStreamingRecording please guide me so that i can make java customize API for my project… Aslo guide me to learn best way ---

> [@sheo\_choudhary](#): > > Module class not found or could not be loaded. Sure, we’d be happy to help, but it would require we have full access to your Engine files and logs so we can confirm that the package and classes were configured as expected. The “not found” message usually just means that it was not found defined in the correct location. Tech support doesn’t debug in forums so you’ll need to submit a ticket. But, yes we can help you and guide you. A wowza engineer will work with you directly until it’s working as you’d like… You can submit one here: [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket) ---

Stupid question; but did you copy the JAR file to the /lib folder? If so; please post the entire module code (as an attachment) ---

That post is a mess; better to provide code in proper code blocks or as an attachment. That will also prevent your code being altered by the forum editor (like changing asterisks `*` into _italic_) as happens for your import statements at the top. Check the compilation process; does it say that the module has been compiled successfully? In the code above there’s a missing curly bracket at the end.
