谢谢Willem
给我回信，我在openfire中部署这个Webservice用到的CXF是将SPRING分离的，所以应该不会出现spring版本冲突的问题。现在出现的异常是

org.apache.cxf.BusException: No binding factory for namespace

org.apache.cxf.service.factory.ServiceConstructionException: Could not
resolve a binding for null:

在梁的回复中说到Thread.currentThread().getContextClassLoader()，能说的再详细点吗？

如你所说，openfire在加载插件的时候用到自己的URLClassLoader
，但是我已经将CXF-jar放到了相对应的路径中，我想在初始化BUS的时候用这个URLClassLoader应该是可以找到相应的类的吧？

谢谢你的回复。openfire加载插件其中有一段代码如下：
ClassLoader oldLoader = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(pluginLoader);
plugin.initializePlugin(this, pluginDir);
Thread.currentThread().setContextClassLoader(oldLoader);
其中的pluginLoader就是openfire自定义的，而根据CXF的BUS加载机制，他是先判定Thread.currentThread().getContextClassLoader();是否为空，很显然，轮到他加载的时候不是为空的，而是pluginLoader。不知道我这样理解是否正确呢？

org.apache.cxf.service.factory.ServiceConstructionException: Could not
resolve a binding for http://schemas.xmlsoap.org/wsdl/soap/

依然是这个异常。我将同样的代码放到TOMCAT环境下可以通过，应该可以证明代码没有问题。
