Running Topcoder arena on kubuntu 13.10
By pscs27, 10 years ago, In English

Hi everyone,

I want to run Topcoder arena application on Kubuntu 13.10. I used to use the following command from shell and it used to work fine until today :

javaws -Xignoreheaders -headless Downloads/ContestAppletProd.jnlp &

Today it gave the following error:

from browser: http://goo.gl/joo0Nw from command-line: http://goo.gl/nrqBcF

It would be great if someone could tell me how to run the arena on your Ubuntu system. It would be a great help :)

Thanks!

There was a version 7.1.3 of the Arena applet. It was used at SRM 631.

Now at SRM 632, TopCoder apparently rolled back to a previous 7.1.2 version, and 7.1.3 did not work. It was necessary to downgrade the version on client computers, too, and JavaWS & Arena are apparently unable to detect the problem and recover automatically. This can be done manually by clearing Java Web Start cache, and then re-downloading the Arena.
