Hi,
excuse me, you're right in one aspect. I realized it later that
I didn't read the whole question. I just thought: OH AGAIN. But
this doesn't make the answer wrong.
If you're in a servlet, no matter where, you can get the
ServletContext by getServletContext(). From it you can have for
instance getResourceAsStream("/WEB-INF/file.properties"). If
this doesn't work you might have done something wrong, maybe
with the slashes or so?
If you're not in a servlet, make sure you pass a ServletContext
from a servlet to where you want to have it.
FileIO can be used, but it's not compatible with the spec. The
servlet spec says you are not guarantied to have FileIO other
than the temp directory and temp files. But also this has been
said many times.
However, if you know there is a file system, you can use normal
File IO. What you need is the right path. You could pass it as
an init param in web.xml. From the servlet's init() you can get
the param with getInitParameter("nameOfParam").
What do you mean by starting a standalone application?
