java.lang.ClassNotFoundException: br.com.alura.gerenciador.acao.ListaEmpresasComo está o código da classe ListaEmpresas? Veja se não está usando com letra minúscula
import java.io.IOException; import java.util.List;
import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;
import br.com.alura.gerenciador.modelo.Banco; import br.com.alura.gerenciador.modelo.Empresa;
public class ListaEmpresas implements Acao { public String executa( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("listando empresas");
Banco banco = new Banco();
List<Empresa> lista = banco.getEmpresas();
request.setAttribute("empresas", lista);
return "ListaEmpresas.jsp";
}}
Assim esta o meu código.
