I agree that this is unacceptable.  But I have deployed many hot fixes,
similar to the one line oopsie you mention, and have never had to tear WAS
or Tomcat down to do it.  Nor did I have to use a 3rd party tool to deploy:
I wrote simple CL commands to MOV the objects from hither to yon.  It could
also be done with DOS batch files or a *nix or QSH script.

As you have mentioned in the past, one DOES need to understand the directory
structure used by J2EE, which seems to be identical for WAS 4+ and Tomcat
4+.  Discovering the file structure is not at all difficult in my opinion,
even without looking at any documentation.  I advise beginners to create a
teeny-tiny application, WAR it up and deploy it, then look at the results in
the file system.

Should you be FORCED to do this?  Well, I'm on the fence on how to answer
that.  On the one hand, I'm a programmer, and it's my livelyhood to
understand as much about my little computing universe as I possibly can.  On
the other hand, I realise that not all programmers share my personal view on
the matter.  Today, it seems to me that the web universe is still pretty
young, and people who want to play here should be more propellerhead than
the proverbial average programmer.
