while executing Groupdocs with annotation, following error message popup is being dispayed.
we are using url as follows
Error : HTTPStatus 404 -/LoadFileBrowserTreeDataHandler
could you please help us.
Thank you for your inquiry.
Sorry, but from your request, it is not clear which our product you use. Because you described that you use the GroupDocs.Annotation for Java library , but the url that you mentioned "http://localhost:8080/document-viewer " is for our GroupDocs.Viewer for Java library.
With all our demo samples we have provided a documentation for how to correctly run the sample "README.md" file . So please investigate it and try again to run our library.
