Where is the Java "jar" function

I'm looking to make a jar file out some Java code using jar [options] [name] [files] from the command line but it's not recognized.

According to Oracle Jar is part of the JDK. I have both 7 and 8 installed. How do I run the jar function?

I don't have a C:/Java that the Oracle documents show. I've tried running jar from within the JDK directories and with admin rights.

I'm not putting params in yet, want to check I can at least find the jar function first.

Running jar from JDK directory Running jar from JDK directory(1.8) http://puu.sh/eoer7/4fcd0ce63c.png Running jar from System32 http://puu.sh/eoe3X/076d79b4e4.png

You have displayed two installations of the Java Runtime Environment (or JRE). You need to install a Java Developer Kit (or JDK), to get jar. Set your JAVA_HOME to the installation directory of the JDK, and add it to your PATH.

set "PATH=%PATH%;%JAVA_HOME%\bin"

Also, Using JAR Files: The Basics says (in part) JAR files are packaged with the ZIP file format, and you can use tools that can read and write ZIP files to work with them.
