org.apache.commons.compress.archivers.ArchiveStreamFactory

Factory to create Archive[In|Out]putStreams from names or the first bytes of the InputStream. In order to add other implementations, you should extend ArchiveStreamFactory and override the appropriate methods (and call their implementation from super of course). Compressing a ZIP-File:

 final OutputStream out = new FileOutputStream(output);  ArchiveOutputStream os = new ArchiveStreamFactory().createArchiveOutputStream(ArchiveStreamFactory.ZIP, out); os.putArchiveEntry(new ZipArchiveEntry("testdata/test1.xml")); IOUtils.copy(new FileInputStream(file1), os); os.closeArchiveEntry(); os.putArchiveEntry(new ZipArchiveEntry("testdata/test2.xml")); IOUtils.copy(new FileInputStream(file2), os); os.closeArchiveEntry(); os.close();

Decompressing a ZIP-File:

 final InputStream is = new FileInputStream(input);  ArchiveInputStream in = new ArchiveStreamFactory().createArchiveInputStream(ArchiveStreamFactory.ZIP, is); ZipArchiveEntry entry = (ZipArchiveEntry)in.getNextEntry(); OutputStream out = new FileOutputStream(new File(dir, entry.getName())); IOUtils.copy(in, out); out.close(); in.close();

            new Pack200CompressorOutputStream(new FileOutputStream(output),
                                              mode);
        try {

                .createArchiveOutputStream("jar", out);


            os.putArchiveEntry(new ZipArchiveEntry("testdata/test1.xml"));

            os.closeArchiveEntry();


            os.putArchiveEntry(new ZipArchiveEntry("testdata/test2.xml"));
            IOUtils.copy(new FileInputStream(file2), os);
            os.closeArchiveEntry();


            os.close();
        } finally {
