Getting "java.nio.file.AccessDeniedException" when trying to write to a folder
access-denied, file-io, io, java
Solution
Ok it turns out I was doing something stupid. I hadn't appended the new file name to the path.
I had
rootDirectory = "C:\\safesite_documents"
but it should have been
rootDirectory = "C:\\safesite_documents\\newFile.jpg"
Sorry it was a stupid mistake as always.
Problem
For some reason I keep getting `java.nio.file.AccessDeniedException` every time I try to write to a folder on my computer using a java webapp on Tomcat. This folder has permissions set to full control for everyone on my computer (Windows). Does anybody know why I get this exception? Here's my code: ``` public void saveDocument(String name, String siteID, byte doc[]) { try { Path path = Paths.get(rootDirectory + siteID); if (Files.exists(path)) { System.out.println("Exists: " + path.toString()); Files.write(path, doc); } else { System.out.println("DOesn't exist"); throw new Exception("Directory for Site with ID " + siteID + "doesn't exist"); } } catch (FileSystemException e) { System.out.println("Exception: " + e); e.printStackTrace(); } catch (IOException e ) { System.out.println("Exception: " + e); e.printStackTrace(); } catch (Exception e) { System.out.println("Exception: " + e); e.printStackTrace(); } ``` And here is the error: Exception: java.nio.file.AccessDeniedException: C:\safesite_documents\site1 java.nio.file.AccessDeniedException: C:\safesite_documents\site1 at sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:83) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:97) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:102) at sun.nio.fs.WindowsFileSystemProvider.newByteChannel(WindowsFileSystemProvider.java:230) at java.nio.file.spi.FileSystemProvider.newOutputStream(FileSystemProvider.java:430) at java.nio.file.Files.newOutputStream(Files.java:172) at java.nio.file.Files.write(Files.java:3092) Possible reason why: See my post on supersuser about how I can't uncheck 'Read Only' for any of my folders on windows 7. Even though all the folders aren't read only to anything but java.
