Can't Export runnable jar from eclipse

i'm trying to export a runnable jar from eclipse, but this is the result:

Exception in thread "main" java.lang.NoClassDefFoundError: neg1
Caused by: java.lang.ClassNotFoundException: neg1
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

This is the manifest:

Manifest-Version: 1.0
Rsrc-Class-Path: ./ itextpdf-5.4.3.jar itext-pdfa-5.4.3.jar itext-xtra
 -5.4.3.jar
Class-Path: .
Rsrc-Main-Class: Negozio.Start
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader

And this is how the files are packed into the jar:

Where Operazioni and Negozio are the my packages and the itext are the external library

You must have external jars that you did not include when you exported or were not put in your class path. Right click on your project Properties->Java Build Path and then ensure the "Libraries" tab is selected. Ensure the jars are added here.

Did you forget to include an external jar file?
