glassfish. Why is the project not deploying?

Question

Java

Started learning Java EE, decided to use Netbeans. At first everything was in order, but after a while an error began to occur when deploying the project on GlassFish. Googling did not help: I ​​tried to remove-add a server, but I did not get rid of the error. What could be the reason and how can it be cured?
(Netbeans 8.0.2, Windows 8.1).

Answer 1

Another error message would be given, it would be absolutely wonderful. Thought readers went on vacation IMHO.
