Hi I am facing Module class not found or could not be loaded. Check [install-dir]/conf/Test/Application.xml to be sure all Modules/Module/Class paths are correct: Issue in when started implementing a test module using eclipse. I checked all the name, package name. I even restarted wowza after building the project. Jar is showing in respective folder and application XML has proper name and class name. I also checked with restarting the system. I am using latest mac version. Wowza is properly installed .Attached are some screenshots of application.xml and eclipse project module. Please let me know what I am missing or doing anything wrong. Thanks in advance ---

Hi Arun, Make sure that you [restart your Wowza services](https://www.wowza.com/docs/how-to-start-and-stop-wowza-streaming-engine-software) after making any changes to your jar file. If you continue to have issues, it is best then to [submit a support ticket](https://www.wowza.com/support/open-ticket) so that we can take a look. Michelle ---

I had the same issue and What I did to solve it: 1. Install a proper JDK version [https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine](https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine) ex) Wowza Engine 4.7.8 -\> JDK 9.0.4 1. eclipse: Right-click on your project and select `"Properties -> Java Compiler"`, check **“Enable project specific settings”** and select the same JDK Version from the **“Compiler compliance settings”** select box. 1. eclipse: Under `Window -> Preferences -> Java -> Compiler`, set Compiler compliance level to the same JDK Version. ---
