First use apache-cxf-2.5.6 to create java class code from WSDL

call .\tools\apache-cxf-2.5.6\bin\wsdl2java -b .\jaxb-bindings.xml -d .\gen .\src\wsdl\UBS_Investment_Suitability_Models.wsdl

jaxb-bindings.xml

<jaxb:bindings version="2.1" 
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
   <jaxb:globalBindings generateElementProperty="false"/> 
</jaxb:bindings>

Those are supported third-parties library

activation.jar
jaxb-api-2.2.1.jar
jaxb-impl-2.1.3.jar
stax2-api-3.1.1.jar
stax-api-1.0.jar
woodstox-core-asl-4.1.2.jar

We use Unmarshaller/Marshaller transfer between java object ( it is created by CXF from WSDL) and xml string.

The following is java code

public VRResponse ummarshaller(String xml) throws Exception {
		JAXBContext jaxbCtx = JAXBContext.newInstance(VRResponse.class);
		Unmarshaller ummarshaller = jaxbCtx.createUnmarshaller();
		// marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8"); // NOI18N
		// marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
		// Boolean.TRUE);
		XMLInputFactory xif = XMLInputFactory.newInstance();
		XMLStreamReader xsr = xif.createXMLStreamReader(new StringReader(xml));
		xsr.nextTag(); // Advance to Envelope tag
		xsr.nextTag(); // Advance to Body tag
		xsr.nextTag(); // Advance to getNumberResponse tag
		System.out.println(xsr.getNamespaceContext().getNamespaceURI(
				"vrresponse"));

		JAXBElement<VRResponse> object = ummarshaller.unmarshal(xsr,
				VRResponse.class);

		return object.getValue();

	}

	public String marshaller(VRResponse response) throws Exception {
		JAXBContext jaxbCtx = JAXBContext.newInstance(VRResponse.class);
		Marshaller marshaller = jaxbCtx.createMarshaller();
		StringWriter w = new StringWriter();
		marshaller.marshal(response, w);
		return w.getBuffer().toString();

	}

	public VRRequest loadRequest(String fileName) throws Exception {
		JAXBContext jaxbCtx = JAXBContext.newInstance(VRRequest.class);
		Unmarshaller ummarshaller = jaxbCtx.createUnmarshaller();
		// marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8"); // NOI18N
		// marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
		// Boolean.TRUE);
		XMLInputFactory xif = XMLInputFactory.newInstance();
		XMLStreamReader xsr = xif.createXMLStreamReader(new FileReader(this
				.getClass().getResource(fileName).getFile()));
		xsr.nextTag(); // Advance to Envelope tag
		xsr.nextTag(); // Advance to header
		xsr.nextTag(); // Advance to Body tag
		xsr.nextTag(); // Advance to getNumberResponse tag
		System.out.println("serviceName="
				+ xsr.getNamespaceContext().getNamespaceURI("ok"));

		JAXBElement<VRRequest> object = ummarshaller.unmarshal(xsr,
				VRRequest.class);

		return object.getValue();
	}

Here, I need point a issue.

		XMLInputFactory xif = XMLInputFactory.newInstance();
		XMLStreamReader xsr = xif.createXMLStreamReader(new StringReader(xml));
		xsr.nextTag(); // Advance to Envelope tag
		xsr.nextTag(); // Advance to Body tag
		xsr.nextTag(); // Advance to getNumberResponse tag
		System.out.println(xsr.getNamespaceContext().getNamespaceURI(
				"vrresponse"));

		JAXBElement<VRResponse> object = ummarshaller.unmarshal(xsr,
				VRResponse.class);

因为JAXB不能解析

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>

例如，soap messge xml string is

With the help of "woodstox-core-asl-4.1.2.jar", we can skip some tag, so JAXB can understand.

为什么？因为CXF生成java的代码是依赖WSDL. 但是WSDL没有包括soap信封的定义
