That simple example looks good to me. Can you try this procedure?
1. Deploy that simple example with "run as java deploy". Make sure it deploys correctly by watching the output window in eclipse. DS should go to "No Robot Code" for a moment and then back to "Disable".
2. Teleop-Enable the DS.
3. Check for DS errors in the DS messages view, make sure it's empty.
4. Look at Talon SRs connected to PWM channel 0 and PWM channel 1 since that's what the example uses. Are they both blinking orange? Or just one is blinking orange?
5. Disable robot and replace PWM cable with a fresh one. Re-teleop-enable. Still blinking orange?
Make sure the black wire on the PWM cable is on the correct side marked 'B' on the Talon housing.
Also make sure the PWM connector is seated all the way down in the Talon side.
Double check the PWM connector on the RIO side. Make sure the black wire is the outside of the RIO.
6. Disable robot and replace Talon with another Talon. Or if you are only using one Talon, move it from PWM0 to PWM1. Re-teleop-enable. Still blinking orange?

This should rule out Talon, PWM cable, and bad contacts.
