CVS Question

Hi all,

I just downloaded the source, jar files for javacvs
and was successful in checking out a module from cvs
successfully.
Thanks a lot to all the people who made it possible.

If i want to commit a file using the javacvs classes
how do i do it. 
I am trying to build a simple web-based system thro
which people can download files from a cvs server to
their local machine. Also they can check-in files into
the cvs server. 
I am thinking of using javacvs for this. 
How do i use javacvs classes to commit and update from
the cvs server.

my simplest case is a web-user requests for a file and
from the appserver i get the file from the cvs
repository and stream it back to the web-user. The
user makes some changes to that file and checks-in the
file back into the cvs server.

If anybody can help that would be great.

regards
Ashok Madhavan
