# How to remap service? commit button during camera_calibration doesn't work

Hi, I didn't find accurate answer to this question

I would like to remap service from /set_camera_info to /camera/set_camera_info

according to this instructions: http://wiki.ros.org/Remapping%20Argum... I tried:

```
przemek@przem:~$ rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.025 image:=/image_raw set_camera_info:=/camera/set_camera_info
```

but after pushing on commit button I get: raise ServiceException("service [%s] unavailable"%self.resolved_name) rospy.service.ServiceException: service [/camera/set_camera_info] unavailable

so my camera is calibrated or not?

details from calibration:

```
rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.025 image:=/image_raw set_camera_info:=/camera/set_camera_info

Are you sure that's what your camera's set_camera_info service is called? What do you see when you run

`rosservice list`

?
