Como o erro diz, ele não encontrou a classe Vendedor.
Essa classe existe mesmo?
Ela foi mapeada corretamente? (Eu acho que nesse ponto está o erro)
Dê uma verificada nos seus arquivos de configuração (pelo modo que você iniciou o SessionFactory, você deve estar utilizando o hibernate.cfg.xml).

Outra coisa, no seu exemplo, você está tentando persistir o objeto Supervisor, porém a exception lançada foi no objeto Vendedor, ou seja, o erro não está na classe Teste

a Vendedor ta aqui! (lista 1) inclusive seu mapeamento(lista 2) usei mesmo o hibernate.cfg.xml(lista3) não sei o que está dando errado! lista 1
