java.util.zip.ZipException: invalid CEN header (bad signature)

Question

I\'m getting this error when doing this (relatively simple) piece of code:

    ZipFile zf = new ZipFile(fn);
    Enumeration eze =          


        

Answer 1

7z l -slt output provided in your comment is quite useful:

Type = zip 64-bit

gives a hint, that it's ZIP64 (version 4.5 of ZIP specification). However, though Java7 supports it, this support is not backported to Java6 at the moment and you will have to resort to external library such as Apache Compress.

P.S. For reference, file test.zip would output something like

test.zip: Zip archive data, at least v4.5 to extract
