Chrome packaged app with a Java applet

Is it possible for a Chrome packaged app to contain a Java applet?

I'm attempting to integrate QZ-Print / jZebra into a packaged app, however the applet does not appear and JavaScript receives an error of applet / can't read method of undefined when attempting to call a function.

It will be an ad-hoc solution, but you can set "always allow" manually in chrome://plugins

No, you cannot use any (NPAPI) plugin in a Chrome app.

The documentation lists several Disabled Web Features. Flash and Non-sandboxed plugins are both listed, so they cannot be embedded in a Chrome app. Flash -as a (sandboxed) PPAPI plugin- could be embedded inside a <webview> tag, but Java is a non-sandboxed NPAPI plugin, so it cannot be used in a <webview> tag.

And you cannot use Java applets within a legacy packaged app either, because Java does not support Chrome extensions. You might have more luck if you try to embed the Java applet from a http(s) site.

Note that both Java applets and legacy packaged apps are deprecated and going to be removed from Chrome in the future (announcement for Java plugins, announcement for packaged apps), so you should try to look for alternatives such as native messaging.
