I'm thinking about buying your product (Annotation library).
I wanted to try it and downloaded the trial version.
I tried this example from GitHub (https://github.com/groupdocs-annotation/GroupDocs.Annotation-for-Java/tree/master/Showcase/GroupDocs.Annotation-for-Java-using-Servlets) but it failed with
Failed to load resource: the server responded with a status of 500 (Internal Server Error) document/info?file=candy.pdf.
Because of this feature is one of the most important things I'd like to get if I buy this library.
So I have to know for sure that it properly works.
