Lost the source Luke

I more than likely have to reverse engineer one of our applications
(see the subject line). I have been looking at Jad and JCavaj and the
like. I was wondering what percentage (roughly) of the source I would
get back running it through one of those. Any experience?

In my experience with FrontEnd Plus\Jad is that it you get all back.
Some code is returned not in its original form but with different api's.
Naturally you do not get the original comments. Just try it to see
what you get in return.

Thanks, I am trying that one now. That you get it *all* back it is
good news. I realized the comments thing because comments don't get
compiled down. Ah me for ugly projects.

You will get all the source back. What's missing are comments,
Javadoc, local variable names, expressions used to compute constants
known an compile time.

see http://mindprod.com/bgloss/backup.html

Nowadays there is no excuse for not backing up everything. You can do
it with only a few seconds of effort. The main way you get nailed is
by not taking a backup offsite and somebody steals the works or you
have a fire or flood.
