Chuck, thanks for your response. It turns out that the auto-deploy switch
does affect the situation. New subdirs created after the auto-deploy is
turned off are no longer being treated as separate apps and getRealPath is
returning the path as I expected.
ServletContext.getResourceAsStream() is fine for accessing a file. In my
case, I need to list all the files under an image directory. Here is my
directory structure:
Approot/sub1/test.jsp
Approot/sub1/images/{image files}
test.jsp needs to present a list of all images in the sub1 dir, thus it
needs a File object representing "images". I tried to use
ServletContext.getResource("/sub1/images"), the resultant URL was converted
to an URI with .toURI() and fed to 'new File()'. It didn't work. File(URI)
requires an URI with the "file" scheme.

Using getRealPath() inside an app server of any kind is pretty much always a
Bad Idea. If you need to access a file from your webapp, use
ServletContext.getResourceAsStream(). If you need a place to store a file,
it certainly shouldn't be inside the webapp deployment area, which should be
treated as read-only.
