I'm trying to write a simple GUI file renamer using Netbeans 6.8 on Windows. I am having problems getting the renameTo() method to work.

Can anyone see what I am doing wrong?

It did actually work when I ran it using java -jar from the dist directory in a DOS command window and the file was in the same directory. I'm wondering if it is a permissions problem.

What happens if you use the fullpath of the file, instead of just the filename ?

This line:

File tempFile = new File(file.getName());

discards all the information about the file's path, keeping only the name. Java will therefore be looking for a file by that name in the current directory. If that's where the file is, then the code will work, but if it's anywhere else, it won't. Just don't do this "tempFile" thing -- use the File object you get from the chooser directly.

Thanks, that did it. I can see why now.

I agree. Here's the link:
