Creating a Dispatch Client Using by Only Using the WSDL
Hi,
Currently I'm implementing a Client in CXF using JAX-WS Dispatch API. This
client should be as dynamic as possible. But in the dispatch api, while
creating a service and a dispatch, you need to give Qnames for service name
and port name.
The only input that I have is the wsdl file hosted at the remote service.
At the moment, I'm parsing the wsdl using DOM parser to get the necessary
values as servicename, portname and namespace. Is there any other way than
this to receive these values than parsing the wsdl ?
Thanx...!!
Following is the code that I used.
SpringBusFactory bf = new SpringBusFactory();
URL busFile = Client.class.getResource("/
client.xml");
Bus bus = bf.createBus(busFile.toString());
BusFactory.setDefaultBus(bus);
URL wsdl = new URL("
http://localhost:9000/SoapContext/GreeterPort?wsdl");
HttpURLConnection connection =(HttpURLConnection)
wsdl.openConnection();
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(new
InputSource(connection.getInputStream()));
String service=
document.getElementsByTagName("service").item(0).getAttributes().getNamedItem("name").getNodeValue();
String
port=document.getElementsByTagName("port").item(0).getAttributes().getNamedItem("name").getNodeValue();
String
binding=document.getElementsByTagName("port").item(0).getAttributes().getNamedItem("binding").getNodeValue();
String[] splitTag=binding.split(":");
String
nameSpace=document.getFirstChild().lookupNamespaceURI(splitTag[0]);
QName serviceName = new QName(nameSpace, service);
QName portName = new QName(nameSpace,port);
Service s =Service.create(wsdl,serviceName);
Dispatch<SOAPMessage> dispatch = s.createDispatch(portName,
SOAPMessage.class, Service.Mode.MESSAGE);
InputStream is =
Client.class.getResourceAsStream("/greeterMessage.xml");
if (is == null) {
System.err.println("Failed to create input stream from file
");
System.exit(-1);
}
SOAPMessage soapReq1 =
MessageFactory.newInstance().createMessage(null, is);
dispatch.invoke(soapReq1);
Thread.sleep(30 * 1000);
bus.shutdown(true);

Hi,
Basically the WSDL can contain more than one service and multiple ports inside one service.
Therefore, in case of specifying WSDL location, Dispatch should know what exactly will be called.
Any chance to specify service name and port name can be specified as configuration parameters?
If you do not use WSDL related features (WS-Policies, schema validation, etc), consider to create the service without WSDL location. In this case service name and port name doesn't really matter, you can use any:
QName serviceName = new QName("http://org.apache.cxf", "stockQuoteReporter");
Service s = Service.create(serviceName);
QName portName = new QName("http://org.apache.cxf", "stockQuoteReporterPort");
Dispatch<DOMSource> dispatch = s.createDispatch(portName,
DOMSource.class,
Service.Mode.PAYLOAD);
...
Regards,
Andrei.
