Why can't I activate pistons with this layout? [duplicate]

Question

How can I get my redstone to activate adjacent pistons?

I have 4 pistons with the following layout:

  T====
   PPPP

 P: piston
 =: restone wire
 T: redstone torch

When I put the redstone torch the pistons fail to activate and remain still. However if do the following:

   T
   PPPP

The first piston on the left activates as normal.

Shouldn't the redstone wire be enough for activating pistons?

I'm using version 1.2.5 SMP vanilla.

You need to power a block next to the repeater or create a direct input.

To fix that you either need redstone torches or repeaters:

t====
 rrrr
 pppp

or

t====
 tttt
 pppp

or

t====
bbbbb <redstone on top of the blocks
 pppp

 t <t=torch and redstone
pb <from the side

Ah so the redstore wire brings power only along one direction instead of affecting all adiacent cells, like a torch does

Yup, redstone wire only powers in the direction it is pointing.
