It looks as if the jedi is a prestige class specializing in unarmed combatant, very hard to hit & elusive, great movement, with limited "mind powers" & focuses most of his combat with a specialty melee weapon unique to their order. There would be different powers for good jedi vs evil.
to best emulate a jedi's ability I would think Psion fits the bill more than any other
powers: precog defense, psionic suggestion, attaction, aversion, mind thrust, missive, energy adaption, inflict pain, body adjustment, energytk force, tk thrust, aura sight, touchsight, tk mnvr, psychic crush, true seeing, aura alteration, mind blank, shadow body, Psionic Revivify, hustle, energy current, burst, Sensitivity to Psychic Impressions,Clairvoyant Sense,Object Reading, mindlink, crises of breathe, read thoughts, conceal thoughts, lions charge
combination of the monk/psion/kensia/fighter classes.
The weapon they use is not a self generated weapon it is manufactured and would be something their order would provide. All jedi weapons dont have to be the same but they all look as if they would be brialliant energy weapons
