Failing to access a folder by InputStream

Question

I'm trying to access a created folder by FileInputStream, but Tomcat returned an exception.

java.io.FileNotFoundException:(directoy path) access denied.

Here's the code which creates the folder.

String dirname = "Myfolder";
File dir = new File( dirname );
dir.mkdirs();

My problem is that I cannot access this folder by InputStream.

"access denied" - check folder permissions and verify the user running your process can access the folder ... — Markus, Dec 15 '15 at 08:33

You can't access a directory with FileInputStream. You can read a file in the directory, or you can list the contents of the directory with e.g. new File(directory).listFiles().

Print out absolute path of this directory and make sure you are in the right place.

log.debug(">>> " + dir.getAbsolutePath());

And then check if user running JVM has access to that directory or even if it exists.

You can't open a directory with FileInputStream. To copy a directory, you can use the Files.copy(Path, Path, CopyOption...) method from JDK7:

String dirname = "Myfolder";
File dir = new File(dirname);
dir.mkdirs();
// ...
Files.copy(dir.toPath(), Paths.get("/target"), StandardCopyOption.REPLACE_EXISTING);

See this page from the Java Tutorial for more information: http://docs.oracle.com/javase/tutorial/essential/io/copy.html
