通常情况下,在JAX-WS2.0中是利用JAXB将传入的SOAP XML消息转换成JAVA的object,然后调用对应porttype的JAVA类的相应的方法,在完成调用后,再通过JAXB将返回参数转成SOAP XML.
JAX-WS还提供了另一种方法,让我们可以直接操作SOAP XML,通过让对应porttype的JAVA类实现 Provider<Source>接口,当服务器端收到SOAP消息后,会调用 Source invoke(Source payload) 方法,如果需要直接对XML进行操作,不想利用JAXB来做对象和XML的转换,可以用这种机制.
例子:(用CXF发布web service)参照http://blog.csdn.net/kkdelta/archive/2009/03/12/3984312.aspx了解CXF发布的步骤.
