Pack200, specified in JSR 200 (J2SE 1.5), deprecated in JEP 336 (Java SE 11) and removed in JEP 367 (Java SE 14), is a compacting archive format developed by Sun, capable of reducing JAR file sizes by up to a factor of 9, with a factor of 3 to 4 seen in practice. Pack200 is optimized for compressing JAR archive files, specifically the Java bytecode portion of the JAR files. Applications of this technology include faster Java application deployment over Java Web Start. After Pack200, gzip compression is usually applied. In HTTP compression, such content is specified by the Content-Encoding type pack200-gzip. When stored as a file, the extension .pack.gz is used. Pack200 may also refer to the Pack200 compression tools (pack200 and unpack200) provided in the Java Development Kit from Java 5 until Java 14. (en) Pack200 è un algoritmo di compressione lossy sviluppato da Sun per la compressione degli archivi JAR. Descritto nella 200, è stato introdotto in Java 1.5.0. I comandi pack200 e unpack200 sono inclusi nei Java Deployment Tools. (it) Pack200是Sun为更快地在网络上传输JAR文件而在JSR 200中提出的一种HTTP压缩方式。Pack200也可以指代从Sun JDK 1.50版就开始提供的Pack200压缩工具以及Pack200压缩文件。 在HTTP压缩方式中，Pack200可以和GZIP压缩格式协同使用(这种情况下被称为“pack200-gzip”)以提供比只使用GZIP压缩格式更高的压缩率。Pack200专为压缩JAR文件（尤其是其中的字节码部分）而优化。此技术也应用于Java Web Start的Java程序部署中。 (zh) |
