Jax Pavan 479,333,495 was one of the 582,797,754 Human males named Jax Pavan on Coruscant. He was a nighttime security guard for Chancellor Palpatine, but he didn't do his job...or anything for that matter. Often he would fall asleep or play with the Chancellor's Sith lightsabers (Chancellor Palpatine a Sith? How shocking!). Palpy still liked him and gave him promotions. His colleagues despised him and called him "Lax Jax".
After Palpatine became Emperor, Jax was "let go," whereupon he moved to Nabooboo and joined the security forces there. Back on Coruscant, his former co-workers referre to him as "Ex-Lax Jax."
