| /** |
| * This package provides methods to read files from a JAR file and to |
| * transform them to a more compact transfer format called Pack200. |
| * It also provides methods to receive the transmitted data and expand |
| * it into a JAR file equivalent to the original JAR file. |
| * |
| * <p> |
| * The {@code pack} methods may be used by application developers who |
| * wish to deploy large JARs on the web. The {@code unpack} methods |
| * may be used by deployment applications such as Java Web Start and |
| * Java Plugin. |
| * |
| * <p> |
| * In typical use, the packed output should be further compressed |
| * using a suitable tool such as gzip or |
| * {@code java.util.zip.GZIPOutputStream}. The resulting file (with |
| * a suffix ".pack.gz") should be hosted on a HTTP/1.1 compliant |
| * server, which will be capable of handling "Accept-Encoding", as |
| * specified by the HTTP 1.1 RFC2616 specification. |
| * |
| * <p> |
| * <b>NOTE:</b> It is recommended that the original ".jar" file be |
| * hosted in addition to the ".pack.gz" file, so that older client |
| * implementations will continue to work reliably. (On-demand |
| * compression by the server is not recommended.) |
| * |
| * <p> |
| * When a client application requests a ".jar" file (call it |
| * "Large.jar"), the client will transmit the headers |
| * "Content-Type=application/x-java-archive" as well as |
| * "Accept-Encoding=pack200-gzip". This indicates to the server that |
| * the client application desires an version of the file encoded with |
| * Pack200 and further compressed with gzip. |
| * |
| * <p> |
| * The server implementation will typically check for the existence of |
| * "Large.pack.gz". If that file is available, the server will |
| * transmit it with the headers "Content-Encoding=pack200-gzip" and |
| * "Content-Type=application/x-java-archive". |
| * |
| * <p> |
| * If the ".pack.gz" file, is not available, then the server will |
| * transmit the original ".jar" with "Content-Encoding=null" and |
| * "Content-Type=application/x-java-archive". |
| * |
| * <p> |
| * A MIME type of "application/x-java-pack200" may be specified by the |
| * client application to indicate a ".pack" file is required. |
| * However, this has limited capability, and is not recommended. |
