Question

我将EAR从一个JBoss 5.1服务器移动到另一个，我之前复制了服务器。旧的一切都很好，现在我收到了这个错误，我不明白，它试图告诉我的是什么：

[[/ KD-Dokumente]] StandardWrapper.Throwable org.glassfish.jersey.internal.ServiceConfigurationError： org.glassfish.jersey.internal.spi.AutoDiscoverable：该类

如果有人能翻译它，我会很高兴，我可以想象缺少一个依赖，因为它说＆＃39;提供者接口org.glassfish.jersey.internal.spi.Auto Discoverable无法实例化：null＆＃39 ;，所以如果某些东西是空的，它就不存在。

我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

和我的申请类：

public class REST extends Application {

    private TimerTask cloudWatchService = new CloudWatchService();
    private Timer timer = new Timer();
    private final static int oneSecond = 1000;
    private final static int oneMinute = oneSecond * 60;

    public REST() {
        timer.schedule(cloudWatchService, oneSecond * 3, oneMinute);
    }

    @Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> resources = new HashSet<Class<?>>();

        // Add your resources.
        resources.add(Versand.class);

        return resources;
    }
}

谢谢。
