Extracting .jar file with command line

I am trying to extract the files from a .jar file. How do I do that using command line?

I am running Windows 7

Solution

  • From the docs:

    To extract the files from a jar file, use x, as in:

    C:\Java> jar xf myFile.jar

    To extract only certain files from a jar file, supply their filenames:

    C:\Java> jar xf myFile.jar foo bar

    The folder where jar is probably isn't C:\Java for you, on my Windows partition it's:

    C:\Program Files (x86)\Java\jdk[some_version_here]\bin

    Unless the location of jar is in your path environment variable, you'll have to specify the full path/run the program from inside the folder.

    EDIT: Here's another article, specifically focussed on extracting JARs: http://docs.oracle.com/javase/tutorial/deployment/jar/unpack.html
