Extracting jar to specified directory

There is no such option available in jar command itself. Look into the documentation:

-C dir Temporarily changes directories (cd dir) during execution of the jar command while processing the following inputfiles argument. Its operation is intended to be similar to the -C option of the UNIX tar utility. For example: jar uf foo.jar -C classes bar.class changes to the classes directory and add the bar.class from that directory to foo.jar. The following command, jar uf foo.jar -C classes . -C bin xyz.class changes to the classes directory and adds to foo.jar all files within the classes directory (without creating a classes directory in the jar file), then changes back to the original directory before changing to the bin directory to add xyz.class to foo.jar. If classes holds files bar1 and bar2, then here's what the jar file contains using jar tf foo.jar: META-INF/

META-INF/MANIFEST.MF

bar1

bar2

xyz.class

It's better to do this.

Navigate to the folder structure you require

Use the command

jar -xvf  'Path_to_ur_Jar_file'

In case you don't want to change your current working directory, it might be easier to run extract command in a subshell like this.

mkdir -p "/path/to/target-dir"
(cd "/path/to/target-dir" && exec jar -xf "/path/to/your/war-file.war")

You can then execute this script from any working directory.

jars use zip compression so you can use any unzip utility.

Example:

$ unzip myJar.jar -d ./directoryToExtractTo
