Thanks for your inquiry. We have successfully reproduced your reported issue at our end. This issue occurs when application is unable to find file/s in storage directory of the application. And it can be resolved by putting some file/document of supported format in GroupDocs.Annotation-for-Java\Showcase\GroupDocs.Annotation-for-Java-using-Servlets\storage.

Furthermore, we’d recommend you to use this showcase project in order to explore GroupDocs.Annotation for Java API. We shall appreciate your cooperation in this regard.

Thanks for your reply. I clone new project that you recommended me, but still got the same Exception.
