What is Topcoder Arena

How do I run ContestAppletProd.jnlp?

I've seen a lot of people face similar problems. The Topcoder arena just doesn't start and shows a Java exception. Here is the list of solutions that might help you.

Before trying this, I would recommend that you check that you have the latest version of Java installed.

Solution 1:

It doesn't matter if you are using Windows, Linux or Mac, go to Terminal / CMD and run the command

Javaws viewer

(without quotation marks). When you run this command you will be taken to the Java applet cache windows. Delete the application that appears there and restart your arena. For the most part, you should be able to start your arena. If you can't start your arena yet, try solution 2

Solution 2:

Sometimes the Topcoder Arena applet takes a long time to run, which can exceed the Javaws timeout value. Fortunately, javaws gives us a command line option to change the timeout value. Run this command to start the Topcoder arena with increased timeout:

javaws -J-Dcom.topcoder.net.httptunnel.client.connect.timeout = X http://www.topcoder.com/contest/arena/ContestAppletProd.jnlp

I hope it helps. :) :)
