Deploying WAR in TomEE

There is a difference between ClassNotFoundException and NoClassDefFoundError

ClassNotFoundException: the class you were looking for could not be found.

NoClassDefFoundError: some other Class your own class needs could not be loaded.

Essentially com.app.auth.AuthenticationService is there, but it is missing some class it depends on.
So you are essentially missing some jar in your WAR.

I have my WAR inside webapps of TomEE. After delpoying, when I try to run the
application, it says it is not able to see the classes that are present
under Project/WEB-INF/classes.
I created the WAR file from eclipse by right clicking the project and
selecting Export as WAR file.
I also tried packaging those classes into a separate jar and loaded that jar
under WEB-INF/lib.
I am not sure why it is not able to see the classes that are undeployed
under WEB-INF/classes.
Could someone please help me with this ?
