Launch webstart without downloading...?

I have made a Java webstart application, and created an HTML page with the link to launch it. The problem is, in Google Chrome, there is no option to just 'Open' a file without saving it. I want to make an HTML page that can automatically launch a JNLP file without having to save it. Or rather, without the user having to open their file explorer to launch it) Is this possible?

Solution

  • Launch the JNLP using an embedded applet deployed using web start.

    1. Start with a Swing based JApplet that accepts an image path (icon) and a string for the button. Deploy the applet (embedded in the web page, where the link would be) using JWS.
    2. When the user clicks the button, use the BasicService.showDocument(URL) method to launch the JWS (frame based) app. As I note in the demo. of the BasicService..

      ..In Java 6+, a call to show another web start launch file (e.g. BasiceService.showDocument(another.jnlp)) will be handed directly to JavaWS, with no browser window appearing.
