Question

我使用JAX-WS创建了一个简单的Web服务，但我期待一个恼人的问题。

我的网络服务代码是这样的：

@WebService
public class UpdateList implements IUpdateList {

    public UpdateList() {
    }

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

}

我使用wsimport生成了客户端代码并为其创建了一个简单的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强制转换异常：

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

然后我才意识到它可能是一些依赖冲突，所以我运行mvn dependency:tree，它很干净，我唯一的deps是hibernate，guava，guice和jaxws-rt。（你可以看到，在我的webservice示例中，它没有使用任何引用的依赖项，但是当我解决这个问题时，我会尽快完成。）

嗯，完整列表，对于客户：

我认为我的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内容。

有人已经通过了这个吗？有什么建议吗？感谢

看起来你正在捆绑一个JAXP实现com.sun.xml.bind:jaxb-impl:jar:2.2.6:compile。尝试将范围更改为<scope>provided</scope>。与com.sun.xml.ws:jaxws-rt:jar:2.2.6-2:compile相同。

事实上，应该提供大部分内容。
