Unfortunately your horse doesn't have as much training as you think, running at jumps and over jumping are big big indicators of a greenie over fences. Did YOU train him to jump, or did this "training" come with your horse? Are you currently working with a trainer, and how high are you jumping? Are you jumping lines, courses or single fences?
It's hard to help if we don't have answers to the above- right off the bat I'd recommend lots of circles, lots of trotting to jumps and trotting away, halting after the fences, grid work, cross rails, heck start at poles on the ground and start moving back up again.
