JavaFX/Webview not loading Stone web viewer

[Charles Waweru]

Hi all,

Our team is trying to load the Stone Web Viewer via JavaFX/Webview/WebEngine. The Webview component loads the Orthanic explorer succesfully and allows us to select a patient and the target study. However, the Stone Web Viewer starts to load but does not dispaly the images. The images can be viewed successfully on regular browsers.

We have noticed that Orthanc Web Browser loads the static images successfully. I have attached snapshots of the screens that we are getting.

Can the JavaFX/Webview component work for us that way?

Thank you,

Charles

Hello,

From what you describe, it looks like JavaFX/WebView does *not* support WebAssembly, upon which the Stone Web viewer is built:

https://caniuse.com/wasm

Get in touch with the support team of JavaFX for a confirmation.
