Failed to load main class during war

Question

I create my project using maven and generated a * .war file with the following content structure:

META-INF
- maven
-- net.avedo.spozz
--- Spozz-Webservice
---- pom.properties
---- pom.xml
- MANIFEST.MF
WEB-INF
- classes
-- net
--- avedo
---- spozz
----- Spozz.class
----- models
------ ...
----- services
------ ...
-- psql-custom.properties
- lib
-- ...
- web.xml

If I try to run the generated war file using java -jar spozz.war, I get the following error:

Error: Could not find or load main class net.avedo.spozz.Spozz

What did I misunderstand? Please find the manifest file and maven-war plugin definition in pom.xmlbelow.
