How to configure tomcat to read files on mapped network drive

If I run the file reader of S:\test.txt as an application out side of TOM cat is fine. If I run it in tomcat through JSP page, it says "Path not found" Can some one help?

Thanks

Inside of a web application you need to absolute paths, not relative paths like "test.txt", because a web app has no notion of a default directory. Or are you actually using "S:\\test.xt" as path? You could investigate by having the JSP print out the full path.

Thanks for replying. I did use the absolute path "s:\\test.txt" . If I put the file on my local drive and I put "C:\test.txt" in FileReader(), it works. If I put the file to S drive which is a mapped network drive and put "S:\test.txt" in FileReader(), it does not work.

There are something related to Tomcat login user permission. Do you think so?

I'm not all that familiar with using Windows network drives in Java, but you can try using the UNC naming convention, i.e. "\\server\share\file_path" instead.
