webservice注意事项

1、private static final QName PORT_NAME = new QName("http://server.helloworld.cxf.demo/","HelloWorldPort");

一定要在HelloWorld后面加上Port，不然会报如下错误：

Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Fault string, and possibly fault code, not set
at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:161)
at com.sun.proxy.$Proxy35.sayHello(Unknown Source)
at demo.cxf.helloworld.Client.main(Client.java:21)

2、private static final QName PORT_NAME = new QName("http://server.helloworld.cxf.demo/","HelloWorldPort");

"http://server.helloworld.cxf.demo/"默认一定是接口所在包的逆序路径，而不是实现类所在包的逆序路径，

否则会包如下错误

Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Fault string, and possibly fault code, not set
at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:161)

3、private static final QName PORT_NAME = new QName("http://server.helloworld.cxf.demo/","HelloWorldPort");

"http://server.helloworld.cxf.demo/"最后一个"/"必须得要，否则会报如下错误

Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Fault string, and possibly fault code, not set

4、而private static final QName SERVICE_NAME = new QName("http://server.helloworld.cddxf.demo/","HelloWorldffgg");

没有如此多的要求，好像怎么命名都行

5、private static final QName PORT_NAME = new QName("http://server.helloworld.cxf.demo/","HelloWorldPort");

“HelloWorldPort”必须是接口名+Port，换成其他的都不行，
