Problems when switching to java from labview

We decided we will switch to java from labview but when we wrote an example program and tried to put it on the robot, Nothing worked (sidecar showed 1-4 relay ports on for some reason) Yes, we formatted, we tried in safemode also. It is an 8 slot CRIO-I. We tried switching cables between the CRIO and the sidecar, nothing worked. Help?

What was the program supposed to do? Can you post the code?
