Class funcionario

public class Funcionario {    
    private String nome;
    private String Cpf;
    private int Rg;

    public Funcionario(String nome, String Cpf, int Rg) {
        this.nome = nome;
        this.Cpf = Cpf;
        this.Rg = Rg;
    }

    public Funcionario() {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getCpf() {
        return Cpf;
    }

    public void setCpf(String Cpf) {
        this.Cpf = Cpf;
    }

    public int getRg() {
        return Rg;
    }

    public void setRg(int Rg) {
        this.Rg = Rg;
    }           
}

Class FuncionarioDao

public class FuncionarioDao {

    private Conexao Con;

    public FuncionarioDao(){
     Con = new Conexao();
    }      

    public Boolean salvarDados(Funcionario execute){

        try {
            String query = "insert into func (nome,cpf,rg) values(?,?,?)";
            PreparedStatement stmt = Con.getConnection().prepareStatement(query);

            stmt.setString(1, execute.getNome());
            stmt.setString(2, execute.getCpf());
            stmt.setInt(3, execute.getRg());

            stmt.execute();
            Con.getConnection().commit();
            stmt.close();

            return true;
        } catch (SQLException ex) {
            Logger.getLogger(FuncionarioDao.class.getName()).log(Level.SEVERE, null, ex);
        }
        return true;
    }        
}

Class Controle

@ManagedBean
@SessionScoped
public class Controle implements Serializable{

    private Funcionario novo;

    public Controle(){
        novo = new Funcionario();
    }   

    public boolean inserirFunc(Funcionario novoFun){
        FuncionarioDao dao = new FuncionarioDao();
        dao.salvarDados(novoFun);
        return true;
    }     

    public Funcionario getNovo() {
        return novo;
    }

    public void setNovo(Funcionario novo) {
        this.novo = novo;
    }

}

The error I’m getting is:

Unable to create instance for class: br.com.testeControle.Control.

You are calling the constructor Control, this in turn calls the constructor Funcio (no parameters), which is parameterized to trigger an exception if called, so your code will always generate an error.

If you will use the Functio constructor without parameters you must remove line containing this exception:

throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
