Synopsis

packedfile

jarfile

Description

unpack200
unpacks a
JAR
file that has been compressed, or

packed , by the

pack200 tool, and optionally additionally
compressed with

gzip . Specify the name of the
packed file and the name of the JAR file to unpack it to on the
command line.

Because

unpack200 is used as part of the Java
installation process, it is a native application that can run on a
system without a Java interpreter.

Options

All unpack200 options exist in both a long form
that begins with a double dash and a single-letter form that begins
with a single dash. When the option requires a value, the value
should be separated from the long form of the option with an equals
sign and no space or should immediately follow the short form with no
intervening space or punctuation.

--deflate-hint= value

-H value

Specifies whether

unpack200 should compress
individual entries in the resulting JAR file.
value must be true,
false, or keep. The default is
keep, which specifies that each JAR entry should
have the same compression that it had in the original JAR file.
