如何阻止cxf尝试接管javax.xml.ws.spi.Provider的默认实现？

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 webservices时，jax实现正被cxf接管，导致此错误，因为我没有安装cxf：

./data/karaf.out:javax.xml.ws.spi.FactoryFinder$ConfigurationError:Provider org.apache.cxf.jaxws.spi.ProviderImpl未找到

我已经创建了META-INF\services\javax.xml.ws.spi.Provider文件，其内容为com.sun.xml.internal.ws.spi.ProviderImpl，但是在Karaf中这似乎没有注册

有没有想过为什么它会在没有引用cxf的情况下尝试加载cxf？还是有其他方法强制使用默认实现

非常感谢

对于ref，是provider.provide（）方法，该方法似乎正在尝试加载cxf实现

/** 
 * 
 * Creates a new provider object. 
 * <p>
 * The algorithm used to locate the provider subclass to use consists 
 * of the following steps: 
 * <p>
 * <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. 
 * </li>
 * </ul>

首先，您不应该安装CXF捆绑包，其次，您需要向系统捆绑包公开“com.sun.xml.internal.ws.spi”包。

事实证明，Karaf包含FactoryFinder.java的和实现，它在lib/approved文件夹中查找CXF实现。 我刚刚删除了这个文件夹
