Can Java webstart dialog caption be overridden?

Question

I have an Angular web application as well as a client JavaFX program that I host on an IIS 7 web server. When user clicks on a link on a page in the web app, I construct the proper JNLP file and send it down to the browser. The client browser then opens the JNLP file and the app loads and then opens properly. No issues.

But the webstart dialog that appears after clicking on the link shows a progress bar as it downloads the java application from the server, and it's got a caption that says 'JavaFX Application Preview'. I'd much rather have it say the name of the software the user is downloading. Is this possible? If so, where should I start looking?

I hunted online and couldn't find a single mention of this, which I find really surprising. Surely this has come up before?

Answer 1

Create a custom Preloader and in the start method of the preloader, set the title of the preloader stage.
