Which version of WinZip is compatible with java.util.zip?
[*] You need WinZip version 6.2 or later. Version 6.1 or earlier is not good enough. WinZip can be downloaded from http://www.winzip.com/download.cgi. The pkzip software works fine. Infozip is better than WinZip because it lacks the winzip “feature” of failing to recreate directories unless given a special option. Use Infozip.
