Why doesn't this java work

[splatter]

Hey all,

This is from the proxomitron webpage that says you can pass url commands
directly to the proxy and get back a source or debugged information for the
page your viewing. Unfortunately I can't get it to work and was hoping
someone could tell me why.

javascript:document.nolocation="http://src//"+document.nolocation.href.sub
string(7);

Thanks in advance

DP
