Hi Andreas,
A simple example can be found here:
roslaunch pr2_examples_gazebo single_link.launch
roslaunch pr2_controller_manager controller_manager.launch
then you can see your link in rviz
rosrun rviz rviz
Set fixed and target frames to /world and try sending a command to the
controller by
rostopic pub /test_controller/command std_msgs/Float64 0.1
you should see the link approach target joint position in gazebo and in
rviz.
