A bit off-topic, but wanted to jump in and clear this up, as the Java
error messages are somewhat misleading.
If I write a class to open a read-only file with
java.io.FileOutputStream, I will see this stack trace
calder@stimpy:~/bin> ./jdk180-221/bin/java AccessDenied
java.io.FileNotFoundException: tester.txt (Permission denied)
at java.io.FileOutputStream.open0(Native Method)
...
calder@stimpy:~/bin> ls -l tester.txt
-r--r--r-- 1 calder users 0 Jun 9 10:12 tester.txt
FileOutputStream ctors and methods throw the FileNotFoundException and
the more specific error [in this case] is "Permission denied".
So yea, it's confusing.
If you check the source code for FileNotFoundException, we even see a
comment related to this
[quote]
This exception will be thrown by the {@link FileInputStream}, {@link
FileOutputStream}, and {@link RandomAccessFile} constructors when a file
with the specified pathname does not exist. It will also be thrown by these
constructors if the file does exist but for some reason is inaccessible, for
example when an attempt is made to open a read-only file for writing.
