Question

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

这是我的PxOrderManager的代码：

package no.solarsoft.venus2.payex.wsclient;

import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;

import no.solarsoft.venus2.admissionweb2.AdmissionWebUI;
import no.solarsoft.venus2.admissionweb2.AdmissionWebUI.RuntimeMode;

import com.payex.external.pxorder.PxOrder;
import com.payex.external.pxorder.PxOrderSoap;

public class PxOrderManager {

    private static final QName SERVICE_NAME = new QName("http://external.payex.com/PxOrder/", "PxOrder");
    private static final String TEST_WSDL_LOCATION_STRING = "https://test-external.payex.com/pxorder/pxorder.asmx?WSDL";
    private static final String WSDL_LOCATION_STRING = "https://external.payex.com/pxorder/pxorder.asmx?WSDL";
    private static final URL WSDL_LOCATION;

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

    // This initializes WSDL location. !!! USE TEST_WSDL_LOCATION_STRING for
    // testing against test web services.
    static {
        URL url = null;
        String urlString = null;
        try {
            urlString = AdmissionWebUI.RUNTIME_MODE.equals(RuntimeMode.PRODUCTION) ? WSDL_LOCATION_STRING
                    : TEST_WSDL_LOCATION_STRING;
            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war文件的内容，看起来很正常。班级PxOrderManagerSingletonHolder和PxOrderManager存在

我的所有jar文件都在web-inf/lib文件夹中。我正在使用vaadin 7和jdk 1.6.0_45（如果它有帮助）

我希望有人可以帮助我。谢谢！

Answer 1

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

引起：java.lang.IllegalStateException：MASM0001：找不到默认配置文件[jaxws-tubes-default.xml]

解决方案描述为here at SO。

编辑：

此外，考虑Java版本升级会很棒。 Vaadin Book说：

Vaadin与Java 1.6及更高版本兼容。使用WebSockets进行正确的服务器推送支持需要Java EE 7。

NoClassDefFoundError Singletonholder
