Problem Loading Java Code

I'm starting to get pretty stumped.

EDIT: It also tells me when I'm loading code:


[cRIO] Information: No user-supplied RobotMain()

Is this possibly a problem?

OK so, now I have a slightly different problem:

I fixed the aforementioned issue (thanks to all who confirmed that that's what it was) and have (as far as I know) successfully loaded code onto the robot. However, there's a minor issue: nothing happens.

I'm still working on troubleshooting this issue, and I'm not by any means tapped out, but if anyone has any suggestions, I would very much appreciate them. A few facts:

1. I have communication established between robot and DS.
2. The code is supposed to be tank-drive - I essentially copied the code in the doc.
3. Nothing happens when I activate the joysticks.

EDIT: One problem was that I had two projects running. One was blank and selected as the main project; the other had the code in it and was NOT selected as the main project. However fixing this did NOT solve the problem (frowny face).


Here's my code:

From your post I believe it is that your tela operated function is not being called/running correctly, so why don't you try a line of code that does not require feedback, to see if that is the problem, you could just have the robot drive strait for a few seconds to test the function

for instance you could try

 
 public void operatorControl() 
    {
        
            drivetrain.Drive(1, 0);
            Timer.delay(0.005);
 
    }
