ZIP problem on Netware
Below there is a program which updates an OpenOffice file, in fact a zip file.
It works fine on window but on Netware I receive an exception
java.util.zip.ZipException: invalid entry CRC-32
(expected oxffffffffc0f3d518 but got 0xc0f3d518)
Any ideas is great appreciated. Thanks!
(JDK 1.4.2 on both OS)
