General J2EE: Class to process zip files

  1. Class to process zip files (7 messages)

    Hi Is there an open source library that can help me unzip an InputStream that contains a zip doument and obtain an InputStream for each file inside the zip?.

    Why not use java.util.zip.ZipInputStream from the JDK?

    Thanks for the reply But I'm having problems with this approach. If I do: input = new ZipInputStream (file.getInputStream ()); while ((entry = input.getNextEntry ()) != null) { content = new byte [(int) entry.getSize ()]; input.read (content); output = new FileOutputStream (file.getName ()); output.write (content); output.close (); } I'm not getting the same files

    It seems that you have to use ZipInputStream in a very specific way to make it work. Also there is a bug since JDK 1.4 that the class will throw an exception if it finds UTF character in the file names.

    here's an example that shows how to read from a zip entry: ================================= jarFile = new JarFile("file.zip"); JarEntry jarEntry = jarFile.getJarEntry("file/in/archive.txt"); InputStream is = jarFile.getInputStream(jarEntry); ================================= if you read from the input you'll get the right content. hope this helps.

  6. this example uses JarFile, but you can use ZipFile/ZipEntry instead, it works exactly the same. Emil.

    I usually use for work with zip files different tools.But once some important zip archives were damaged.And no one of these tools couldn't help me.And a friend recommended to me-[url=http://www.recoverytoolbox.com/recovery_zip_files.html]corrupt zip files recovery software[/url].Software solved my problem easy and for free.

    Or perhaps Jakarta Commons Compress? http://jakarta.apache.org/commons/sandbox/compress/ It is sandbox though, so the first suggestion is probably better? Ben http://www.benwilcock.net
