Archivers and Compressors Commons Compress calls all formats that compress a single stream of data compressor formats while all formats that collect multiple entries inside a single (potentially compressed) archive are archiver formats. The compressor formats supported are gzip, bzip2, xz, lzma, Pack200, DEFLATE, Brotli, DEFLATE64, ZStandard and Z, the archiver formats are 7z, ar, arj, cpio, dump, tar and zip.

Pack200 is a special case as it can only compress JAR files. We currently only provide read support for arj, dump, Brotli, DEFLATE64 and Z. Arj can only read uncompressed archives, 7z can read archives with many compression and encryption algorithms supported by 7z but doesn't support encryption when writing archives. ZipArchiveEntry entry = new ZipArchiveEntry(name); entry.setSize(size); zipOutput.putArchiveEntry(entry); zipOutput.write(contentOfEntry); zipOutput.closeArchiveEntry(); ZipArchiveOutputStream can use some internal optimizations exploiting SeekableByteChannel if it knows it is writing to a seekable output rather than a non-seekable stream. If you are writing to a file, you should use the constructor that accepts a File or SeekableByteChannel argument rather than the one using an OutputStream or the factory method in ArchiveStreamFactory. Reading entries from an zip archive.

Jar In general, JAR archives are ZIP files, so the JAR package supports all options provided by the ZIP package. To be interoperable JAR archives should always be created using the UTF-8 encoding for file names (which is the default). Archives created using JarArchiveOutputStream will implicitly add a JarMarker extra field to the very first archive entry of the archive which will make Solaris recognize them as Java archives and allows them to be used as executables.

Note that ArchiveStreamFactory doesn't distinguish ZIP archives from JAR archives, so if you use the one-argument createArchiveInputStream method on a JAR archive, it will still return the more generic ZipArchiveInputStream. The JarArchiveEntry class contains fields for certificates and attributes that are planned to be supported in the future but are not supported as of Compress 1.

Adding an entry to a jar archive. 7z Note that Commons Compress currently only supports a subset of compression and encryption algorithms used for 7z archives.

For writing only uncompressed entries, LZMA, LZMA2, BZIP2 and Deflate are supported - reading also supports AES-256/SHA-256 and DEFLATE64. Multipart archives are not supported at all. 7z archives can use multiple compression and encryption methods as well as filters combined as a pipeline of methods for its entries. Prior to Compress 1.8 you could only specify a single method when creating archives - reading archives using more than one method has been possible before. Starting with Compress 1.8 it is possible to configure the full pipeline using the setContentMethods method of SevenZOutputFile.
