Error when attempting private simulation
Posted: Oct 13, 2006 09:23:02 PM

We've been hving difficulties getting a private simulation to work. We've setup a new project the way that the Help file directed us. While viewing games.xml we add our team and a sample team. After hitting run the following error occurs "Could not find the main class. Program will exit.", followed by, "java.lang.NoClassDefFoundError: com/ibm/jgfw/Launcher - Exception in thread 'main'". We've yet to make any changes or additions to the MyShaceShip class. After we recieved the error the first time we added a sub-class to MySpaceShip public static void main () { }, just to see if the simulation would start. No dice... We're just beggining to build our MySpaceShip class but I don't see why the simulation wouldn't run with an "empty" MySpaceShip class. Help would be appreciated. :D

Hi,
i was wondering if you solved that problem, because i am having a similar problem with the private simulation:

The same Exception is thrown if i attempt to run a private simulation with other ships that came in the server snapshot.
If i run a private simulation with only the examples it works.
