unwar and unjar an application

["Mihamina Rakotomandimby (R12y)" <mi...@lab.vectoris.fr>]

Hi,
A developer gave me just a .war file to deploy on a tomcat.
I read [w|j]ar files are just zipped.
The .war contains some .jar...

I would like to "explode" all the .war (and the contained jars) and have 
the full code source. I could do it manually. But then there are two 
questions:

- How to jar and war the exploded code back (to get it all archived it 
it was)?
- if I unarchive some .jar, they dont unarchive in a subdir but directly 
in the current dir. How to manage that (when unarchiving _and_ 
re-archiving)?

Well, the developper used some environment, I want to
- put the code under SVN
- edit it with Emacs/JDE

That's why I need to get it all clear.
Thank you for any advice.

Java classes in a .jar or .war file are normally compiled .class files 
(java byte code), not .java source.  A .war file may also contain .jsp 
files, which typically do have the page source in them, which is then 
compiled by the servlet engine (tomcat).  .Jars and particularly .war's 
get big because they often contain all the dependencies as well, and 
because a complex program takes a lot of code whether it's in source or 
compiled form.

Often the following will unpack a jar or war (both):

jar -xf <the war or jar>

To deplay the application, they usually put the WAR into the webapp 
directory and they it runs: I concluded the source code is in there.

In case the war dont contain the source code:
- Where is the application code?
- Why do they need to upload that big file (1.1Mo big in my case)?

The last section of my post was to explain the goal, so that people 
could understand my request. Obviously I did not expect some indication 
about that.

Are you sure that the WAR and its contained JARs actually have source 
code? They don't by default (and I've never seen one that does)...

These aren't really Tomcat-specific questions at all :( I'd advise 
taking each question and finding its answer via your favorite search engine.
