Regarding creation of jar file
<p>I want to create a jar file through command window in windows. I was observing that you must have <code>jar</code> command included in System PATH variable. You can check this by typing <code>"jar"</code> in the command prompt if it doesn't throw an error <code>"jar is not recognized as an internal or external command"</code>. In my case it is throwing the error. What path variable needs to be set for this? Is there any open source software to create a jar? Please advise.</p>

<pre><code>javin@localhost:~/Java jar -cvf HelloWorld.jar
</code></pre>
