西洛！
我正在尝试使用CXF创建一个Web服务客户端。我的应用程序在OSGi中。我使用Felix框架。
但会发生以下错误：

我说这可能是因为不同的类加载器。有可能吗？
你知道如何解决这个问题吗？
谢谢你！

是的，看起来你有两个BusFactory类定义。SpringBusFactory实现其中一个，asSubclass（）调用在另一个上进行。由于一个BusFactory与另一个不是同一个类，你会得到一个CCE。寻找两个包含BusFactory类的不同包。其中一个将由定义SpringBusFactory的包导入。

我认为“两个BusFactory类定义”是转移注意力的。
不确定您使用的是哪个版本的CXF（猜测是2.4.2），但在查找子类实现时，该代码试图使用线程上下文类加载器来执行ServiceLoader之类的操作。
我最好的猜测是CXF依赖于某种Spring“魔法”，而你缺少提供它的包。看看Karaf的CXF特性，它有大量的依赖项，检查一下并确保你已经得到了所有的依赖项--在这一点上，使用安装了CXF特性的Karaf来尝试这一点可能更容易。
如果您使用的是maven，则可以使用以下命令访问features文件：

<dependency>
        <groupId>org.apache.cxf.karaf</groupId>
        <artifactId>apache-cxf</artifactId>
        <version>2.4.2</version>
        <type>xml</type>
        <classifier>features</classifier>
    </dependency>

我在过去的pax-exam中看到过类似的奇怪错误。在“正常”的OSGi环境中，这是否在pax-exam之外运行？Talend Service Factory（http://talend.com/products/tsf）有几个在OSGi中运行的CXF客户端和服务的示例（在单独的示例下载包中），它们都可以工作。
