java - NoClassDefFoundError Singletonholder

Question

大家好!我最近部署了一个 Web 项目，在尝试获取单例类的实例时收到 NoClassDefFoundError 错误。

这是我的 PxOrderManager 的代码:

    private static final Logger log = LogManager.getLogger(PxOrderManager.class);

            url = new URL(urlString);
        } catch (MalformedURLException e) {
            java.util.logging.Logger.getLogger(PxOrder.class.getName()).log(java.util.logging.Level.INFO,
                    "Can not initialize the default wsdl from {0}", urlString);
        }
        WSDL_LOCATION = url;
    }

    private PxOrder service;
    private PxOrderSoap port;

    private PxOrderManager() {
        init(WSDL_LOCATION);
    }

    private static class PxOrderManagerSingletonHolder {
        public static final PxOrderManager INSTANCE = new PxOrderManager();
    }

    public static PxOrderManager getInstance() {
        return PxOrderManagerSingletonHolder.INSTANCE;
    }

    private void init(URL wsdlUrl) {
        log.info("Initializing web service with wsdl location at: " + wsdlUrl.toString());
        service = new PxOrder(wsdlUrl, SERVICE_NAME);
        port = service.getPxOrderSoap();
    }

    public PxOrderSoap getPort() {
        return this.port;
    }
}

我尝试检查我的 war 文件的内容，它看起来正常。类 PxOrderManagerSingletonHolder 和 PxOrderManager 存在

我的所有 jar 文件都位于 web-inf/lib 文件夹中。我正在使用 vaadin 7 和 jdk 1.6.0_45(如果有帮助的话)

我希望有人能帮助我。谢谢!

我认为你的问题出在不同的地方(不是NoClassDefFoundError)。在你的堆栈跟踪中有这样的信息:

Caused by: java.lang.IllegalStateException: MASM0001: Default configuration file [ jaxws-tubes-default.xml ] was not found

解决方案描述here at SO .

编辑:

此外，考虑Java版本升级也是很好的。 Vaadin Book说:

Vaadin is compatible with Java 1.6 and later editions. Java EE 7 is required for proper server push support with WebSockets.
