java -jar filename.jarWe always assumed that creating META-INF/MANIFEST.MF with the following settings would work:-
Main-Class: com.mydomain.mypackage.MainIt will work if the library files are outside the bundled jar file (containing the Main class) in the same directory.
| | MANIFEST.MF
| | Main-Class: com.mydomain.mypackage.Main
| | Class-Path: spring.jar
| | Main.class
The Java classloader does not know how to load classes from a Jar inside a Jar. The entries on the
Class-Pathmust be references to files outside the Jar file, defeating the goal of delivering an application in a single Jar file.
The solution is to use : Fat Jar Eclipse Plugin. The tutorial is pretty neat and explains how to convert your Main method and bundle other library files along with it using Fat Jar plugin. Fat jar essentially explodes all the library files. It allows you to select a Main Class and creates a MANIFEST.MF file.
Now you can distribute one jar file to your customers :-)
