Welcome to GroupDocs Forum!

We’ve reproduced this issue on our side. While these logs are printed to the console the app should work as expected and produce the output. We’ve created the issue in our internal bug-tracker with ID VIEWERJAVA-2753 and will update you as soon as we have any new information.

Thanks, yes it works. Is there any spring web example of how to send the HTML to the browser where all the pages are shown? I am trying to render docx in the browser with all the pages and thumbnails. Any examples of this are appreciated.


Thank you for your feedback.

Please check our Spring Demo - https://github.com/groupdocs-viewer/GroupDocs.Viewer-for-Java/tree/master/Demos/Spring.

After a brief investigation, we’ve got more information about An illegal reflective access operation has occurred. We’re using reflection in our code and the newer versions of Java log warnings. While these warnings should not affect documents rendering we’ll try resolving this issue at our side.
