Are you seeing an error like below when you try to unzip a file which was zipped using the java.util.zip.ZipOutputStream
If the answer is YES, then check how you are closing the ZipOutputStream in your code. The ZipOutputStream should be closed before calling the toByteArray() of your ByteArrayOutputStream
The documentation of ByteArrayOutputStream says
https://docs.oracle.com/javase/8/docs/api/java/io/ByteArrayOutputStream.html
Or are you seeing an error like below when you unzip from Linux
unzip myfile.zip
Archive: myfile.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of
myfile.zip or
myfile.zip.zip, and cannot find
myfile.ZIP, period.If the answer is YES, then check how you are closing the ZipOutputStream in your code. The ZipOutputStream should be closed before calling the toByteArray() of your ByteArrayOutputStream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try(ZipOutputStream zos = new ZipOutputStream(baos);) {
zip(zos, incidentDir, incidentDir);
zos.flush();
baos.flush();
}
catch (Exception e) {
throw new Exception("Unable to Zip the folder");
}
byte[] result = baos.toByteArray();
The documentation of ByteArrayOutputStream says
The methods in this class can be called after the stream has been closed without generating an IOException.
