A:
Using the JAR command:
jar cf jar-file input-file(s)
Using Maven:
<packaging>jar</packaging>
Using Ant:
<jar destfile="${dist}/lib/app.jar" basedir="${build}/classes"/>

@Sundhas - you want to put `.class` files in your JAR, not source files.

@Sundhas - Here is a concrete example "jar cf my.jar My.class"

To execute a jar file: java -jar app.jarYou will also need to have a MANIFEST.MF file in the META-INF directory that define the Main-class like this:Manifest-Version: 1.0Created-By: 1.6.0 (Sun Microsystems Inc.)Main-Class: MyPackage.MyClass

Take a look at this link: http://java.sun.com/docs/books/tutorial/deployment/jar/appman.html

A:
Command line:
jar cf jarfile [ -C dir ] inputfiles
Make sure you are jar-ing from the root of the directory matching your package hierarchy, rather than just the directory with the class files. The directory structure needs to match the hierarchy.
Also, if you want the JAR to be executable, you need to include a MANIFEST.MF containing a Main-class entry specifying which class should be used as the entry point (this class must define a public static void main(String[] args)).
Netbeans: here is a link to a tutorial.

There are many ways (enough already answered here), but if you want a REALLY SIMPLE way, look at Maven. It just works: http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
