Hi,
I'm one of the developers of DrJava. I'm not at all familiar with CodeRally, but I just tried to take a look at it.
1) One thing you definitely need is the osgi.core.jar file from this website:
http://osgi.org/osgi_technology/download_specs2.asp?section=2
You'll have to enter your information, and then you'll get an email with a download address. This OSGi code is apparently some kind of library that Eclipse uses and DrJava doesn't, so you need to get it separately.
2) In the DrJava Preferences, you should add the osgi.core.jar and the com.ibm.games_3.1.0.jar to the "Extra Classpath" (Preferences, Resource Locations; here's a link to the corresponding section in DrJava's Quick Start Guide: http://drjava.org/quickstartdocs/preferences.html#RESOURCELOCATIONS ).
3) You should probably also add the com.ibm.games.coderally_3.1.0.jar to the "Extra Classpath".
Steps 1 and 2 allow you to do the following:
4) Now you can type the following in the "Interactions Pane":
> java com.ibm.jgfw.Launcher
You'll get an error message from IBM's gaming software:
IBM Gaming v3.1.0
Usage:
java -jar games.jar
mode
where
mode is one of:
-spectate
path
-playlist
path

Since I have no idea what this project is even supposed to do, how it should be started in Eclipse, and since I don't have the source code from IBM, I cannot help you further. I'm sorry.
If you manage to get the instructions about how to run CodeRally outside of Eclipse (e.g. on the command line) from IBM, then I'm sure I or someone else on the DrJava development team can help you. In that case, please contact us directly at javaplt@rice.edu. I just stumbled across this post by accident.
Good luck!
Yours,
Mathias Ricken
