Zipfile not recognizing source

Question

i have a wierd problem. my very simple app sometimes recognizes a .zip file and sometimes throws an unknown source error. the error seems to occur when the zip file was originally created on a mac-- although stuffit can recognize and open these files without any problem. furthermore, when i open one of these files, then rezip it on my windows box, java recognizes the file.
most of the time this does nothing, correctly. other times, it will not recognize the file. i run this with the file in the same directory, and with the same name, so i'm pretty sure it's not a file not found issue.
here's the code:
import java.util.*;
import java.util.zip.*;
public class tester {
public static void main (String[] args) {
new tester().tester1(args[0]);
public void tester1 (String zipName) {
try{
ZipFile zip = new ZipFile(zipName);
} catch (Exception ex) {
System.out.println(ex);
ex.printStackTrace();
the error:
java.util.zip.ZipException: error in opening zip file
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(Unknown Source)
at java.util.zip.ZipFile.<init>(Unknown Source)
at tester.tester1(tester.java:16)
at tester.main(tester.java:10)
thank you

Do your files have special characters, like �, �, �, etc?
