Question

import java.io.File;
public class Main {
    public static void main(String[] args) {
        File file = new File(args[0]);
        System.out.println("exec:" + file.canExecute());
        System.out.println("read:" + file.canRead());
        System.out.println("write:" + file.canWrite());
      System.out.println(file.setLastModified(System.currentTimeMillis()));
} Compile it to ~. In ~ create file aaa.txt. Next

false setLastModified return false and modification time of file remain the same. Why?

Answer 1

Can you see if the file is getting to the webserver's (not
ColdFusion)
temp file directory?
When a file is uploaded from the browser the
webserver(IIS|Apache|etc)
upload it to a temp location, then all CFFile does is copy
the file
from the temp directory to where ever specified.
So you can see if the problem is failing before or after this
point.
