file.lastmodified

[Steve Rainbird]

Why on my Windows Vista box does file.lastmodified() always return zero but
on my Linux box it returns the correct value?

Why on my Windows Vista box does file.lastmodified()

Did you mean the File.lastModified() method?
I have not heard of the other one and cannot
comment on it.

.. always return zero but
on my Linux box it returns the correct value?

What does this print on the Vista box?

<sscce>
public class LastModified {

public static void main(String[] args) {
java.io.File file = new
java.io.File("LastModified.java");
System.out.println( file.lastModified() );
}
}
<sscce>

BTW - did you read the JavaDocs for that method?
There are two reasons listed, as to why the method
may return '0'.

Andrew,

Thanks ,that displays the correct result. I think it must be a permissions
problem. I will look into it further.

Does the file exit? Has an I/O error occurred?

Fixed it.

I was getting a directory listing and then trying to find out the
LastModified of those files. But I forgot to add the path onto the
beginning of the file name.

Linux worked because I was looking for files in the current directory.

DOH!

Works fine on my Vista box. Have you an sscce to prove the bug.

Do you have permission to look at the file in question?
