there is a belief in an afterlife in Judaism, tho judaism doesn't make it the main focus of its faith.
as to reincarnation, there are those who believe in it as a part of Tikkun Olam, fixing the world, that we are reincarnated so that we can accomplish what we were meant to accomplish.
since there is not much on the afterlife there is alot of room for different views, i think.
