Decryption Help

[GoogleCodeExporter]

Hi, I'm new on this and I don't konw very much about this project jet
(haven't take look at the source code), I'm trying to decrypt a protected
zip file and I'm getting the following exception:

java.util.zip.ZipException: expected 'extra field header ID' (0x9901) not
neither found in central directory nor local file header

    at com.ghr.test.zip.UnzipTest.unzipFile(UnzipTest.java:28)
    at com.ghr.test.zip.UnzipTest.main(UnzipTest.java:42)

by now I only want to list the zip entries with the following code:

  itEntries = decrypter.getEntryList().iterator();

  while(itEntries.hasNext()) {
    entry = itEntries.next();
    System.out.println("Entry: " + entry.getName());
  }

The password is: moco

Which program did you use to create the zip file?

The sample provided was "encrypted" with the unsecure Zip 2.0 compatible
"encryption". This library is intended for the safer 256-Bit AES encryption 
mode.
