jacoboliveira: para gerar o XML corretamente Agradeço a resposta. Eu estava observando um código mais a frente e verifiquei que havia a declaração de um drive. Eu fiz parecido e deu certo: XStream xStream = new XStream(new Dom4JDriver()); Mas a questão é: Isso está correto? O que diabos eu fiz. O bom é que deu certo! rsrsrs

Erro com SXtream

Tenho o seguinte código, que estou trabalhando no NETBEANS, aparentemente não está nada errado, porém não roda. O erro, depurando, está na linha do XStream:

@Override
public void start(Stage stage) throws Exception {
    
//        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
//        
//        Scene scene = new Scene(root);
//
//        stage.setScene(scene);
//        stage.show();
    
    gravaEndereco();
//        gravaListaEndereco();
//        gravaListaCompleta();
//        
//        lerXML();

}

private static void gravaEndereco() {

Endereco endereco = new Endereco();
    endereco.setCidade("Primavera do Leste");
    endereco.setRua("Rua das araras");

    **XStream xStream = new XStream();**
    xStream.alias("endereco", Endereco.class);

    File arquivo = new File("endereco.xml");
    FileOutputStream gravar;
    try {
        gravar = new FileOutputStream(arquivo);
        gravar.write(xStream.toXML(endereco).getBytes());
        gravar.close();
    } catch (IOException ex) {
        //ex.printStackTrace();
    }
    
}

Eu tenho a classe, o e também os arquivos xstream-1.4.9.redhat-2.jar e dom4j-1.6.1.jar. Aparece o seguinte erro, que para mim é ilegível:

Olá @AndreNF, seu código esta normal pode algumas dependências que esteja faltando veja:

No código abaixo fiz só algumas alterações para gerar o XML corretamente

` Endereco endereco = new Endereco();
    endereco.setCidade("Primavera do Leste");
    endereco.setRua("Rua das araras");
    XStream xStream = new XStream() {
        @Override
        protected MapperWrapper wrapMapper(MapperWrapper next) {
            return new MapperWrapper(next) {
                @Override
                @SuppressWarnings("rawtypes")
                public boolean shouldSerializeMember(Class definedIn, String fieldName) {

                    if (fieldName.indexOf("this$") != -1) {
                        return false;
                    }
                    System.out.println(definedIn);
                    return super.shouldSerializeMember(definedIn, fieldName);
                }
            };
        }
    };
    xStream.alias("endereco", Endereco.class);

    File arquivo = new File("C:\\endereco.xml");

    try (FileOutputStream gravar = new FileOutputStream(arquivo)) {

        gravar.write(xStream.toXML(endereco).getBytes());
    } catch (IOException ex) {
        Logger.getLogger(TestXStream.class.getName()).log(Level.SEVERE, null, ex);
    }
