JBoss AS7中的JAX-WS，获取强制转换异常

Question

我使用JAX-WS创建了一个简单的WS服务，但我预计会出现一个新问题。

我的webservice代码是这样的：

@WebService
public class UpdateList implements IUpdateList {

    public UpdateList() {
    }

    @Override
    public Collection<Long> getFrom(Long version) {
        System.out.println("test");
        return new ArrayList<Long>();
    }

}

我用wsimport生成了客户端代码，并为它创建了一个简单的main：

public class App {

    public static void main(String[] args) {
        System.out.println(new UpdateListService().getUpdateListPort().getFrom(183L));
    }
}

但是，当我运行它时，我得到了一个无法解释的类类型转换异常：

Exception in thread "main" java.lang.ExceptionInInitializerError
    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source)
    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source)
    at com.sun.xml.internal.ws.client.sei.SEIStub.invoke(Unknown Source)
    at $Proxy29.getFrom(Unknown Source)
    at com.test.App.main(App.java:8)
Caused by: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContext
    at com.sun.xml.internal.ws.fault.SOAPFaultBuilder.<clinit>(Unknown Source)
    ... 5 more

然后我意识到这可能是一些依赖冲突，所以我运行了mvn dependency:tree，它很干净，我唯一的副手是hibernate，guava，guice和jaxws-rt。(您可以在我的see服务示例中看到，它没有使用任何引用的依赖项，但我很快就会这样做，当我修复这个问题时)。

我结束了这个想法，认为我的jboss中缺少一些配置或jar文件。我做了一些研究，但没有发现任何相关的东西。

已经有人通过这个了？有什么建议吗？谢谢

看起来您正在捆绑JAXP实现com.sun.xml.bind:jaxb-impl:jar:2.2.6:compile。尝试将作用域更改为<scope>provided</scope>。com.sun.xml.ws:jaxws-rt:jar:2.2.6-2:compile也是如此。

事实上，其中大多数都应该提供。
