missing run.py from rosjava_bootstrap

edit

Hi, I'm trying to do the "Getting started with NXT leJOS, using nxt_lejos_proxy" tutorial (http://www.ros.org/wiki/nxt_lejos_proxy/Tutorials/Getting%20Started#Create_a_Scratch_Package), but when i run "roslaunch proxy.launch" I get this error:

ERROR: cannot launch node of type [rosjava_bootstrap/run.py]: Cannot locate node of type [run.py] in package [rosjava_bootstrap].

Looking into my rosjava_bootstrap folder there isn't any run.py file. I've seen that this file is present in the rosjava electric-tag release (http://code.google.com/p/rosjava/source/browse/?name=electric-tag) but I don't know how to download it. Can someone give a tip?

Thank you in advance,

Camilla
