I'm not aware that a servlet container, such as Tomcat,
makes any guarantee's about what:
curDir = new File("images");
is going to be relative too. As a result,:
filenames = curDir.list();
results in an empty array. You might use:
application.getRealPath("/images");
to get a full path in a portable way to pass
to your FileBean. I don't think the FileBean
can assume anything about relative paths. It
needs to be told by the caller.
Cheers,
Larry
