Hi,
In the ideal world, the steps to download Java are:
1) Reimage the cRIO with the Java specific image.
2) Update Netbeans with the FRC plugins.
3) In Netbeans, in Tools>Options>Misc>FRC Configuration, update the Team Number.
4) Hit Run and cross your fingers
I assume all your networking is up and running properly (i.e., you should be able to ping the cRIO).
You can find more detailed information at

Hope that helps!
