Java SE (Java Platform, Standard Edition)

Hi everyone,
I would like to say thanks to all who participate in this forum because it is one of the most important part of the java community.

I am having some problems with a desktop application that am workin on at this time. Having a small window that allows the user of the application to use a JFileChooser to choose a directory (Directory only option enabled) where they want to store there file and also a JTextField that allows the user to enter the file name they wish the file to be called, I am having problem when the user enters a file name with characters that are not allowed in a file.

I was wondering if there is a standard way of validating file names across several platform or does anybody have any tips and tricks for getting around this problem.

Thanks in advance
