Running Topcoder arena in fedora

I hope everybody who is very interested in doing topcoder matches , must have tried to run the applet in Fedora ( as in ubuntu it works out of box )
This is small tutorial kind of to run the applet .. in fedora .. hope u all guys enjoy this ...and start participating in the topcoder matches

Download the following from the sun site :-

1) jre
2) jdk

Then follow the steps properly :-

Code:



$ sudo cp <path to jre from sun > /opt/
$ sudo cp <path to jdk from sun > /opt/
$ sudo chmod u+x jre* jdk*
$ sudo ./jdk* && ./jre*
Then accept the following conditons and press enter untill u encounter
yes or no option
Then press yes to continue or no to abort

// Find the configuration of java
$ sudo /usr/sbin/update-alternatives --config java
Then
$ sudo /usr/sbin/update-alternatives --install /usr/bin/java java /opt/sunjre/bin/java  3 ( give the proper name to jre ..ie jre1.6..)
$ java -version
 
The o/p should be :-
[code]
java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)
[/code]

Similarly do the above for javac ( u shld get this after the execution of sun jdk ..)
and for javaws ( java web start )..

All Glories to Sri Guru and Gauranga !!

The above method / way is configuring sun java by default .. in fedora rather that open-jdk ...

is it necessary to change to sun jdk?

It didn't not start ..for me...
I hope this might not be the case with others..
