Camera

[2869Robotics]

When I try and run this code, I get the following exception. I am programming in Java, so why does my exception include something relating to WindRiver? I'm trying to store an image on the cRIO and then I plan to retrieve the images using FTP.

AxisCamera cam = AxisCamera.getInstance("192.168.0.90");
cam.getImage().write("image.jpg");
