用wsdl4j来解析一个服务的wsdl文档，如何可以得到服务的名字和服务方法的名字？
如下代码：
String wsdlURL = "http://127.0.0.1:8080/axis/HelloService.jws?wsdl ";
WSDLFactory wsdlFactory;
try {
wsdlFactory = WSDLFactoryImpl.newInstance();
WSDLReader wsdlReader = wsdlFactory.newWSDLReader();
wsdlReader.setFeature( "javax.wsdl.verbose ",false);
wsdlReader.setFeature( "javax.wsdl.importDocuments ",true);
Definition def = wsdlReader.readWSDL(null,wsdlURL);
//显示结果
System.out.println( "element: "+def.getPortTypes());
这里只能得到wsdl的getPortTypes的标签，但是它里面的方法名和服务名却不知道如何得到，十在是头痛的事情啊！

void analysisWSDL() throws Exception{
operations=new Hashtable();
WSDLFactory factory = WSDLFactory .newInstance();
WSDLReader reader = factory.newWSDLReader();
DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
fac.setNamespaceAware(true);
DocumentBuilder builder = fac.newDocumentBuilder();
Document doc = builder.parse(new ByteArrayInputStream(wsdl.getBytes( "UTF-8 ")));
Definition def = reader.readWSDL(null,doc);
//一个WSDL可以定义多个服务,我只取了第一个
Service service = (Service) getFirstItem(def.getServices());
Map ports = service.getPorts();
Iterator iter = ports.values().iterator();
String url=null;
Port port=null;
ExtensibilityElement tmp=null;
while(iter.hasNext())
{
port = (Port)iter.next();
tmp= (ExtensibilityElement)port.getExtensibilityElements().get(0);
url = getLocationURI(tmp);
if(url!=null)
break;
}
//修改
soapVersion = getSoapVersion(tmp.getElementType().getNamespaceURI());
//多个接口的问题？
Binding binding = port.getBinding();
List operationList = binding.getBindingOperations();
int size = operationList.size();

for (int i = 0; i < size; i++) {

addOperation(analysisOperation(oper));
}
}

}
}

}
private String getNamespaceURI(ExtensibilityElement body)throws Exception {

return ((SOAP12BodyImpl)body).getNamespaceURI();
if(body instanceof SOAPBodyImpl)

}
private int getSoapVersion(String namespace) {
if (namespace.equals( "http://schemas.xmlsoap.org/wsdl/soap/ ")) {
return 11;
}
if (namespace.equals( "http://schemas.xmlsoap.org/wsdl/soap12/ ")) {
return 12;
}
return 0;
}
}
WSDL还是比较复杂的，我很多地方都省了，只取了HTTP-SOAP方式的数据。
