卡拉夫 2.3.2
据我所知，我的代码或容器配置中没有对 Apache cxf 的引用，但是当我尝试使用 Exchange Web 服务时，由于我没有安装 cxf，所以 cxf 接管了 jax 实现，给出了这个错误：
./data/karaf.out:javax.xml.ws.spi.FactoryFinder$ConfigurationError: Provider org.apache.cxf.jaxws.spi.ProviderImpl not found
我已经创建了包含 com.sun.xml.internal.ws.spi.ProviderImpl 内容的 META-INF\services\javax.xml.ws.spi.Provider 文件，但是在 Karaf 中这似乎没有注册。
尽管没有引用 cxf，但为什么它试图加载 cxf 有什么想法吗？还是有另一种强制使用默认实现的方法？
非常感谢
对于 ref，provider.provide() 方法似乎正在尝试加载 cxf 实现

* <ul>
* <li>
* If a resource with the name of
* <code>META-INF/services/javax.xml.ws.spi.Provider</code>
* exists, then its first line, if present, is used as the UTF-8 encoded
* name of the implementation class.
* </li>
* <li>
* If the $java.home/lib/jaxws.properties file exists and it is readable by
* the <code>java.util.Properties.load(InputStream)</code> method and it contains
* an entry whose key is <code>javax.xml.ws.spi.Provider</code>, then the value of
* that entry is used as the name of the implementation class.
* </li>
* <li>
* If a system property with the name <code>javax.xml.ws.spi.Provider</code>
* is defined, then its value is used as the name of the implementation class.
* </li>
* <li>
* Finally, a default implementation class name is used.
