Hi, I am not able to use the applet. It gives the following message:

net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report.

I am using OpenWebStart after facing some errors (I don't remember exactly, there are just too much errors). Therefore I don't know how to execute javaws/browser since it doesn't work. I tried many versions of ContestAppletProd.jnlp and nothing worked.

Can anyone help?

And if this is an universal error, could you update the "How to Compete guide"?

    I can download and open the current version so it must be your settings. I know I had to tinker with settings a lot to get it working.

    What's your JDK version? update-alternatives --config java

        Oh you're on mac? I have no idea if anything works significantly different there.

        I have the same OpenJDK version (1.8.0) so that won't be the problem.

        Try this? Or some equivalent for your JNLP opener — go to settings and try to get stuff validated.

    I don't know if you already resolved this issue, but today I got the same error and found the fix.
