You need to deploy the jar to your robot. I think you can do this in Eclipse with the WPILib plugins by right clicking on the project then Run As > WPILib Java Deploy.

Alternatively, you can run 'ant deploy' on the command line in your source directory.

I am trying to run the toast api simulation, which involves changing the run configuration to include the argument "-sim 'my main class'". So I do need to run it on my computer.
