TopCoder Arena launcher in Ubuntu

well..

that took me some time to create the launcher :D

first i'm running on Ubuntu 9.04, all what i wanted is a launcher to start the Arena without the need to digg into folders for it so i made the icon, put it in the Application launcher and added the command wich was

javaws %ArenaPath%/ContestAppletProd.jnlp

and when i click it, nothing happens

and when running that command in a terminal it outputs:

after some searching i found that this was because of the version of JAVA i use, the default 1.6 but "OpenJDK" so when i used the command

/usr/lib/jvm/java-6-sun/bin/javaws   %ArenaPath%/ContestAppletProd.jnlp

It ran correctly and i added the "-Xnosplash" to the command before the Arena path to disable the JAVA web start splash screen :D

i hope that helps some body like me :)

and for 64-bit users as Mohamad Abd El Fattah said: Let me add for 64-bit users. I like to use (K)Ubuntu 64-bit releases. As the SUN 64-bit JRE doesn't contain javaws or javaw. You have two solutions: 1) sudo apt-get install ia32-sun-java6-bin This will install the 32-bit JRE (including javaws to your linux. Thus, the javaws command will be the sun 32-bit JRE javaws. ... Read More 2) For the second solution, you don't even need the 32-bit SUN Java. Install (actually, extract the 64-bit SUN JRE in your home folder). Then, this bash file will make the 64-bit java run the arena ######################### #!/bin/bash rm ~/ContestApplet.jar # Remove the old jar file wget http://www.topcoder.com/contest/classes/ContestApplet.jar -O ~/ContestApplet.jar # Update it with the new one ~/%PATH_TO_JRE%/bin/java -jar ~/ContestApplet.jar www.topcoder.com 5001 http://tunnel1.topcoder.com/tunnel\?dummy TopCoder # Run the jar file, the arguments needed a little bit search, but they work as is for the current version of the Arena. #########################
You can change the default JRE permanently using the command: update-alternatives --config java 3ashan te5las men el aflam bta3et OpenJDK di 5ales
قشطة انا ان شاء الله قريب أوى هرمى الويندوز, أدعيلى بس ربنا يثبتنى
