Answer
Hi,
You may want to look into a trainer or instructor for guidance and support.  You're probably going to have to start at the beginning if he doesn't have a solid jumping background-- he needs to develop confidence and technique.  If you want to start training yourself, this is my advice:
Start lunging your horse over groundrails if he is already comfortable with walking over poles himself.  Longe on a large 20m circle, and when the horse gets up to the jump, urge him forward and cluck/kiss.  One exercise is to set up 4 heavyweight groundrails about 2 human strides apart around where you usually longe your horse.  Lead him through at the walk first.  Then, when he's comfortable, lead him through at a trot.  If he does well, leave it at that.
The next time you work with him, quickly review this exercise.  Then, longe him over the poles in both directions at the walk, then at the trot.
Next training session, lunge him through the 4 poles at a walk and trot each direction.  Then, make the last pole a little jump.  You can set up cavaletti or just use tiny crossrails propped up with a wood block or something.  Longe him through at a walk and encourage him at the last fence (he should be able to step over it).  The next time, ask for a trot a little before the fence.  If he's good, stop for the day.  If not, go over it again.
Next session, recap for a bit and then reverse the placement of the jump and have him go over it in the other direction.
All of these steps, though they may sound pointless and too time-consuming, are essential to create a good jumper.  
Next, either make the crosspole higher, or remove the poles.  Don't do both at once-- pick one, then when he's comfortable with the new step, do the other one.
To get the jumps higher, use the poles in front of the crosspole-- just raise the crosspole to the height you want it.  Soon, he'll start to actually jump over the fences.  When he begins to canter over them, adust the poles for canter strides.
When he's REALLY balanced over 2' jumps, you can start to ride him over crossrails.  It's very important not to jump him too soon or else he won't be able to deal with balancing both himself and you.  That could be very dangerous.  Take care when you're riding.
Later, take away the groundpoles until there is just one left before the jump.  When he's doing well, you can take that away too.  
When you ride your horse up to the jump, stay seated until right when he jumps.  When horses are just learning to jump, if you get into two-point position early, they can feel abandonned and bail out.  Ride firm but gentle up to the jump, then when you get to it, smoothly rise up into jumping  postion, squeeze your legs, and you can kiss if you want.  You may want to grab a handful of mane.  On the landing, make sure that you don't hit the horse in the mouth by letting your hands be jarred by the momentum.  Sit up quickly and calmly, squeeze your legs and ride on.
I hope this helped you.  If you have any other questions, feel free to respond.  Make sure not to rush your horse, but have fun! :)
