package and run sample application as a JAR with Netbeans

I want to compile and package this sample code:

thufir@dur:~/NetBeansProjects/HelloAsterisk/src$
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$ javac -cp
asterisk-java.jar ExampleCallIn.java
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$ java -cp
asterisk-java.jar org.asteriskjava.fastagi.DefaultAgiServer Apr 20, 2015
12:19:20 PM org.asteriskjava.fastagi.DefaultAgiServer startup INFO:
Listening on *:4573.
^Cthufir@dur:~/NetBeansProjects/HelloAsterisk/src$
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$ ls asterisk-java.jar 
ExampleCallIn.class  ExampleCallIn.java fastagi-mapping.properties
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$ cat ExampleCallIn.java
import org.asteriskjava.fastagi.AgiChannel;
import org.asteriskjava.fastagi.AgiException;
import org.asteriskjava.fastagi.AgiRequest;
import org.asteriskjava.fastagi.BaseAgiScript;

public class ExampleCallIn extends BaseAgiScript {

     @Override public void service(AgiRequest request, AgiChannel channel)
     throws
AgiException {
         answer();
         exec("Playback", "tt-monkeys");
         hangup();
     }
}
thufir@dur:~/NetBeansProjects/HelloAsterisk/src$

in Netbeans. However, there's no main class. When I build it as a JAR in Netbeans:

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ jar -tf HelloAsterisk.jar 
META-INF/
META-INF/MANIFEST.MF
ExampleCallIn.class
asterisk-java.jar
fastagi-mapping.properties
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ java -jar HelloAsterisk.jar 
Error: Could not find or load main class helloasterisk.HelloAsterisk
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$

with the MANIFEST.MF as so:

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ jar -xf HelloAsterisk.jar 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ cat META-INF/MANIFEST.MF 
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.4
Created-By: 1.7.0_75-b13 (Oracle Corporation)
Class-Path: lib/asterisk-java-1.0.0.jar
X-COMMENT: Main-Class will be added automatically by build
Main-Class: helloasterisk.HelloAsterisk

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$

How do I build and package this sample code so that it packages as a JAR which runs with the java -jar command?

I'm reasonably sure that the manifest needs modification. Or, perhaps, when executing with java -jar there are some CLI options which should be passed?

The preferred solution is to customize the manifest so that I can press the "run" button in the IDE to run the JAR.

---------------------------------------------------------------------------------update

I apologize, above there's a jar in a jar because there's a jar file in the src directory. Removing that jar gives:

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ java -jar HelloAsterisk.jar 
Error: Could not find or load main class helloasterisk.HelloAsterisk
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ ls lib/
asterisk-java-1.0.0.jar
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ jar -tf HelloAsterisk.jar 
META-INF/
META-INF/MANIFEST.MF
ExampleCallIn.class
fastagi-mapping.properties
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$

and

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ jar -xf HelloAsterisk.jar 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ 
thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$ cat META-INF/MANIFEST.MF 
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.4
Created-By: 1.7.0_75-b13 (Oracle Corporation)
Class-Path: lib/asterisk-java-1.0.0.jar
X-COMMENT: Main-Class will be added automatically by build
Main-Class: helloasterisk.HelloAsterisk

thufir@dur:~/NetBeansProjects/HelloAsterisk/dist$

From this organization, what should the manifest look like? There's a jar specified with Class-Path: lib/asterisk-java-1.0.0.jar.

Keep in mind, that when executing the .class file from the CLI, there's no main class!

Jar files must not be embedded inside other jar files. That won't work. With the manifest you have, the structure must be

some-folder
    HelloAsterisk.jar 
    lib
       asterisk-java-1.0.0.jar

And then, withing some-folder, you'll be able to run 

java -jar HelloAsterisk.jar

(provided the class helloasterisk.HelloAsterisk indeed exists in one of those two jars).
