Have no idea why im getting that exception

EDIT1 here is principal.Cliente

public class Cliente {
    private String name;

    public Cliente(String name) {
        this.name= name;
    }
}

EDIT 2 removed a bunch of useless code to make it look cleaner

Missing default constructor in principal.Cliente I can say,

public class Cliente{ 
  public Cliente(){}
}

when you are adding more constructors, make sure to keep the default one.

public Cliente(){
   super()
}
