In NetBeans, under the files tab, navigate to "resources\META-INF" and open the file called "MANIFEST.MF", you should see something like this:
Code:
MIDlet-Name: Dev Robot Code (2-5-11)
MIDlet-Version: 1.0.0
MIDlet-Vendor: FIRST
MIDlet-1: RobotMain, , edu.wpi.first.wpilibj.templates.RobotMain
MicroEdition-Profile: IMP-1.0
MicroEdition-Configuration: CLDC-1.1
Can you verify that the line that starts "MIDlet-1" is present? If it is, make sure it lists the right class and package. If it is not there, add it, putting the name of your main robot class and package as shown above.
Hope that helps!
