By the way the java version is 1.4.2_12

I may be going out on a limb, here... but have you considered the possibility that "archiveDirectory" may be null?

An excerpt from the JavaDoc... for the particular constructor being called.

File

public File(String pathname)-- Creates a new File instance by converting the given pathname string into an abstract pathname. If the given string is the empty string, then the result is the empty abstract pathname.

Parameters:
pathname - A pathname string

Throws:
NullPointerException - If the pathname argument is null
