The way I always think about it is the stripe on the diode is the | from the schematic symbol ->|-
Which would also be the opposite of what Tom said, I believe he meant the + comes out of the stripe side. But the stripe side is the cathode (-) and the arrow side is the anode (+). So remember my mnemonic device so you don't get confused: in the symbol ->|- the arrow points in the conventional direction of electricity flow from + to - (not the actual direction in physics, which is backwards O_o [but don't think about that]) and the stripe on the diode is the vertical line |.
