I'm currently using JFileChooser to save a file from my application, and would like to make sure the file name the user is giving does not already exist and does not contain any OS-disallowed filename characters. So far I have

The problem with this code, is that it does not check for bad filename characters (which I can't figure out how to do) and that if the file exists already, it won't take you back to the JFileChooser to correct it (like it will in most other applications ex. Notepad).
Any ideas?

Thanks a bunch,

It is sorta covered in the JavaRanch Style Guide.
