关于CXFNonSpringServlet的用法！

[SkyTiger]

开始的这句：System.setProperty(BusFactory.BUS_FACTORY_PROPERTY_NAME,
"org.apache.cxf.bus.CXFBusFactory");
有什么作用？

使用CXFNonSpringServlet和使用CXFServlet的根本区别是什么，我这里指的是使用方面！

目前我直接使用CXFNonSpringServlet来替换CXFServlet，发生如下错误：

怎么是这个总线？

刚才查了一下commit log[1] 和 JIRA[2] ， 你的这个问题应该是在CXF 2.1.1 中fix了。

这个Bus 是处理非Spring configuration file ， ExtensionManager 是通过JSR250
中的Resource Annotation来完成 CXF Component 的组装工作。

[SkyTiger]

难道NOSPRING的情况，使用的是解析WSDL文件而不是类反射机制来获取元数据信息？
