Use this form to send your jrobots in the arena. First you need an account. Then you can upload the Java class file that includes the algorithms of your robot. If the robot is a new one it is uploaded in the CADETS' arena.
If you want to update an old robot, simply send the new version in a file with the same name. The old file will be overwritten, but the results of the old robot will be retained. That works for both CADETS and VETERANS.
Remember that the class name must begin with two underscores and end with one (e.g. '__MyRobot_') and files must not exceed 20 Kb (20480 bytes).
If you use the compiler of the Java 2 JDK 1.4 or higher, remember to set the -target 1.1 -source 1.2 options, because the class version produced by that compiler is incompatible with the JVM of some old Internet Explorer browsers and a number of on-line matches will not be recorded. For example, to compile a robot you can write the line "javac -g:none -O -target 1.1 -source 1.2 __MyRobot_.java".
