Can I use the approach of having all the files sitting on a single NFS file

Not to mention creating a single point of failure.
Alternatively, keep local copies on each server and use rsync to
maintain consistent images.
Not to mention possible inconsistencies between the different copies..

Imagine you have 4 balanced Tomcats, each of which has its own file
repository, and each of which can potentially run the next upload
request or download request. To/from where does the file get
uploaded/downladed ? (until all rsyncs have run). And if the file is
there twice, but different, which one is correct ? (how would rsync know ?)
There are probably more than one sensible configuration possible.
Choosing the best one would really depend on details of the application.
