Merhaba arkadaslar
Bu bolumde SOAPHandler konusuna devam edecegiz ve bir onceki bolumde Server Side’ini yaptigimiz uygulamanin Client Side tarafini tamamlayacagiz.

wsimport

Onceki bolumde yaptigimiz projeyi kullanacagiz (injavawetrust.jaxws.soaphandler.service) ve Web Service i publish edelim. Sonrasinda command line da , wsimport komutu ile Client dosyalarimizi olusturalim.

 wsimport -keep http://localhost:8888/injavawetrust/hello.jaxws?wsdl

Client Handler

Simdi de Client Side’ta calisacak SOAPHandler implementasyon sinifimizi yazalim.
Bir onceki bolumde oldugu gibi handleMessage metodunu kullanacagiz.
SOAPMessage -> SOAPEnvelope -> SOAPHeader objesini elde ediyoruz.
Sonrasinda addHeaderElement metodunu kullaniyoruz.
Yeni bir element ekliyoruz , degerini addTextNode ile ekledik.
Sonrasinda saveChanges metodu ile islemi tamamliyoruz.

TokenClientHandler.java

package ws.handler;

import java.util.Set;

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPConstants;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPHeaderElement;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class TokenClientHandler implements SOAPHandler<SOAPMessageContext> {

	@Override
	public boolean handleMessage(SOAPMessageContext context) {
		
		// Standard property: message direction, true for outbound messages,
		// false for inbound.
		Boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
		
		//If it is an outgoing message
		if (outbound) {
			System.out.println("TokentClientHandler # handleMessage...");
			try {
				SOAPMessage soapMsg = context.getMessage();
				SOAPEnvelope soapEnv = soapMsg.getSOAPPart().getEnvelope();
				SOAPHeader soapHeader = soapEnv.getHeader();

				// add the property to the header
				QName qname = new QName("http://service.ws.injavawetrust/", "TOKEN");

				// Create a new HeaderElement in order to place the new property
				SOAPHeaderElement soapHeaderElement = soapHeader.addHeaderElement(qname);

				soapHeaderElement.setActor(SOAPConstants.URI_SOAP_ACTOR_NEXT);
				soapHeaderElement.addTextNode("token12345");
				soapMsg.saveChanges();

			} catch (SOAPException e) {
				e.printStackTrace();
			}
		}
		return true;
	}

	@Override
	public boolean handleFault(SOAPMessageContext context) {
		return false;
	}

	@Override
	public void close(MessageContext context) {

	}

	@Override
	public Set<QName> getHeaders() {
		return null;
	}

}

@HandlerChain

@HandlerChain annotation’ini wsimport ile olusturdugumuz MessageWriterImplService sinifina ekleyelim.

Client And Run Application

Client.java

package ws.client;

import java.net.MalformedURLException;

import ws.service.MessageWriterImplService;

public class Client {
	
	public static void main(String[] args) throws MalformedURLException {

		MessageWriterImplService s = new MessageWriterImplService();
		String msg = s.getMessageWriterImplPort().getWelcomeMessage("levent", "erguder");
		System.out.println(msg);

	}
}

Ornegi calistirdigimizda;

TokentClientHandler # handleMessage...
Welcome , levent erguder. This message is sent by MessageWriterImpl#getWelcomeMessage.

TokenHandler#handleMessage working...
