unpack200 - Transforms a packed file produced by pack200(1) into a JAR file for web deployment.

 

unpack200 [ options ] input-file JAR-file

options The command-line options. See Options.

input-file Name of the input file, which can be a pack200 gzip file or a pack200 file. The input can also be JAR file produced by \f3pack200(1) with an effort of \f30, in which case the contents of the input file are copied to the output JAR file with the Pack200 marker.

JAR-file Name of the output JAR file.

The \f3unpack200 command is a native implementation that transforms a packed file produced by \f3pack200\f3(1) into a JAR file. A typical usage follows. In the following example, the \f3myarchive.jar file is produced from \f3myarchive.pack.gz with the default \f3unpack200 command settings.

 
\f3unpack200 myarchive.pack.gz myarchive.jar

 
\f3

-Hvalue --deflate-hint=value

Sets the deflation to be \f3true, \f3false, or \f3keep on all entries within a JAR file. The default mode is \f3keep. If the value is \f3true or \f3false, then the \f3--deflate=hint option overrides the default behavior and sets the deflation mode on all entries within the output JAR file.

-r --remove-pack-file

Removes the input pack file.

-v --verbose

Displays minimal messages. Multiple specifications of this option displays more verbose messages.

-q --quiet

Specifies quiet operation with no messages.

-lfilename --log-file=filename

Specifies a log file where output messages are logged.

-? -h --help

Prints help information about the \f3unpack200 command.

-V --version

Prints version information about the \f3unpack200 command.

-Joption

Passes option to the Java Virtual Machine, where \f3option is one of the options described on the reference page for the Java application launcher. For example, \f3-J-Xms48m sets the startup memory to 48 MB. See java(1).

This command should not be confused with the \f3unpack command. They are distinctly separate products.

The Java SE API Specification provided with the JDK is the superseding authority in case of discrepancies.

The following exit values are returned: 0 for successful completion, and a value that is greater than 0 when an error occurred.
