If you want independent control of mecanum FWD/REV, strafe Left/Right, and rotate (turn) CW/CCW, then you need three inputs.
Arcade drive is for skid steer and does not take 3 inputs.
A 2-axis joystick does not produce 3 outputs (unless you want to use the throttle for the 3rd output).
The mecanumDrive_Cartesian() method in the RobotDrive.java file in WPILib takes three inputs.
You need a DI (Driver Interface) that gives the driver three controls: one each for fwd/rev, strafe left/right, and rotate CW/CCW.
So your DI could be this:
Y axis of Joystick1 is FWD/REV
X axis of Joystick1 is Strafe Right/Left
X axis of Joystick2 is Rotate CW/CCW.
... and just feed those three outputs into the appropriate 3 inputs of the mecanumDrive_Cartesian() method.
