Greetings to the codeforces community,

I have added an Arch User Repository (AUR) package topcoder-applet to make the installation of TopCoder applet on arch and arch derived Linux distributions easier using just a single command.

The main advantages over following the steps provided by TopCoder officially at INSTALLING TOPCODER'S VINTAGE ARENA are:

No need to find the right version of javaws to run the applet. The package installs the right java dependencies.
Adds an icon to desktop and application launcher allowing users to run the applet with just one click. The package installs itself as any other GUI application.

Installation

Installation with AUR package manager

The package can be installed using your favorite package manager. If you are using yay then the command is:

yay -S topcoder-applet

Installation without AUR package manager

The package can be installed using the following commands:

git clone https://aur.archlinux.org/topcoder-applet.git
cd topcoder-applet
makepkg -si

Note: Since the package is available on AUR any software store with AUR support will have this package listed.

FAQs

Applet launches but says 'Application Blocked by Java Security

Topcoder suggests adding some URLs to java's security exception list. I tried to make the installer add the exception list file directly to the correct directory but that did not work. For the time being, users need to add the exception sites to the list manually. To get past this, open jcontrol using the following command:

/usr/lib/jvm/java-8-jre/jre/bin/jcontrol

Go to the Security tab and add the following URLs to the exception list under Exception Site List:

http://www.topcoder.com
https://www.topcoder.com
http://arena.topcoder.com
https://arena.topcoder.com
https://topcoder.com,
http://topcoder.com

This has been officially mentioned at INSTALLING TOPCODER'S VINTAGE ARENA. Having the installer take care of this step is on the top of the to-do list.
