Hi Cyril,

There are two ways to run a Java class inside a jar :

1. Invoke java by specific the main class explicitly:

    java -cp application.jar:dependency.jar org.foo.Application

2. Rely on the MANIFEST.MF file inside the jar defines the main class
and the classpath, in this case you simply invoke :

    java -jar application.jar

So in your case, either you add the manifest with the expected
Main-Class attribute [1], either you use the first form to start the
application.
