Java Games Won't Work!

Hello,
I created a website quite some time ago and I have put online games on it.
But when I put Adobe Flash Player games they work very well, but when I put a Java game it didn't work.
Here is the link to the game in question:

Even though I enabled Java, it shows me an error and here are the details of the error that you can check yourself on the site:
