zipfile

I'm asking this here because googling this error only gives me hits on writing a zip file, while I'm only trying to read it. I have a unit test where I'm trying to test the following production code: Map<String, String> zipProps = new HashMap<>(); URI zipUri = URI.create("jar:file:" + itemZipPath.toString()); try (FileSystem zipfiles = FileSystems.newFileSystem(zipUri, zipProps)) { // do stuff... } catch (IOException e) { // log an error } However this fails on the line containing the try: java.util.zip.ZipError: zip END header not found at com.sun.nio.zipfs.ZipFileSystem.zerror(ZipFileSystem

I have a zip file whose contents are presented as byte[] but the original file object is not accessible . I want to read the contents of each of the entries. I am able to create a ZipInputStream from a ByteArrayInputStream of the bytes and can read the entries and their names. However I cannot see an easy way to extract the contents of each entry. (I have looked at Apache Commons but cannot see an easy way there either). UPDATE @Rich's code seems to solve the problem, thanks QUERY why do both examples have a multiplier of * 4 (128/512 and 1024*4) ? Rich Seller If you want to process nested zip

I have a buffer of bytes read from a library call and I would like to unzip the content which is a single text file. I tried with zlib , but I get this error: >>> import zlib >>> zlib.decompress(buffer) error: Error -3 while decompressing data: incorrect header check However with ZipFile it works, but I have to use a temporary file: import zipfile f = open('foo.zip', 'wb') f.write(buffer) f.close() z = ZipFile('foo.zip') z.extractall() z.close() with open('foo.txt', 'r') as f: uncompressed_buffer = f.read() Is it possible to use zlib and how can I avoid using a temporary file? Is it possible

I am using the latest version of ionic zip version 1.9.1.8.I have set the property of ionic zip ParallelDeflateThreshold = 0 . The zipping mechanism was working perfectly for the past two months.Suddenly this stopped working.The zipping thread just hangs,ionic zip just created the tmp file and failed to create the zip file. I could easily reproduce this issue even with small file size. My analysis for this issue is as follows The issue was with the latest version of ionic zip, in this case the ionic zip hanged while creating the zip files. We noticed that, a couple of other users who uses this
