Hi,

I'm not aware of special modes for e.g. java log files (although I do
read them very often), but there are certainly some handy general
things:

1) `auto-revert-tail-mode' - see its doc for the description.  Great for
looking at a growing log.  In fact, you don't need `less' or `tail -f'
with it any more.  See also `auto-revert-remote-files' variable.  You
might also want to set `auto-revert-verbose' to nil.

2) `vlf' package (View Large Files).  See its description.  Very
convenient for huge log files.  I use it quite rarely, though.

3) Combined with Tramp (and grep :) these provide enough functionality
for me.
