Karakun Support Forums

I've been struggling with this one for days and can't find out why it's not working. The website I'm using is https://efiling.uscourts.cavc.gov/#webstart . If I follow all the instructions it looks like it's starting but then everything closes immediately. When I looked through the logs (even with debug on) nothing stands out as an issue, it doesn't even give a real error.

Note this works just fine with Oracle Java, just not the Open Web Start. Unfortunately Oracle's maintenance agreement makes it impossible to use.

I've attached the JSP file (I had to rename it as .txt) and the log, does anyone have any ideas what to try?

Your Jnlp file specifies that your Java application is an applet : <applet-desc...

OWS does not support applet. Browsers have stopped supporting Java plugin that would run applets.

You say the it is working with Oracle Java. In which browser are you running the applet?

It works in both Edge and Chrome. Unfortunately the appeals court requires everyone to use it (Until October at least).

I had a look at https://www.uscourts.cavc.gov/documents ... -Win10.pdf.

The applet does not run in a browser (Edge or Chrome). In the browser you can download the k2ajnlp.jsp which is associated with Oracle Java Web Start to run the applet as a stand alone Java application using AppletViewer. The AppletViewer itself was removed since Java 10. Unfortunately, OWS does not support applets.

I can see that the application is provided by the government. They will need to migrate the application from Java Applet to a Java Application since Java Web Start is no longer supported in versions of Java greater than 1.8. You could try https://docs.azul.com/core/icedteaweb/installation for now but it has limitations.
