Using a Message Handler to alter the SOAP Header in a Web Service Client
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPHeader;
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 HeaderHandler implements SOAPHandler {
public boolean handleMessage(SOAPMessageContext smc) {
Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (outboundProperty.booleanValue()) {
SOAPMessage message = smc.getMessage();
try {
SOAPEnvelope envelope = smc.getMessage().getSOAPPart().getEnvelope();
SOAPHeader header = envelope.addHeader();
SOAPElement security =
header.addChildElement("Security", "wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
SOAPElement usernameToken =
security.addChildElement("UsernameToken", "wsse");
usernameToken.addAttribute(new QName("xmlns:wsu"), "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");
SOAPElement username =
usernameToken.addChildElement("Username", "wsse");
username.addTextNode("TestUser");
SOAPElement password =
usernameToken.addChildElement("Password", "wsse");
password.setAttribute("Type", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText");
password.addTextNode("TestPassword");
//Print out the outbound SOAP message to System.out
message.writeTo(System.out);
System.out.println("");
} catch (Exception e) {
e.printStackTrace();
}
} else {
try {
//This handler does nothing with the response from the Web Service so
//we just print out the SOAP message.
SOAPMessage message = smc.getMessage();
message.writeTo(System.out);
System.out.println("");
} catch (Exception ex) {
ex.printStackTrace();
}
}
return outboundProperty;
}
public Set getHeaders() {
//throw new UnsupportedOperationException("Not supported yet.");
return null;
}
public boolean handleFault(SOAPMessageContext context) {
//throw new UnsupportedOperationException("Not supported yet.");
return true;
}
public void close(MessageContext context) {
//throw new UnsupportedOperationException("Not supported yet.");
}
}
The handler resolver that is to contain the SOAP handler above looks like this:
package com.javadb.ws.example;
import java.util.ArrayList;
import java.util.List;
import javax.xml.ws.handler.Handler;
import javax.xml.ws.handler.HandlerResolver;
import javax.xml.ws.handler.PortInfo;
/**
*
* @author www.javadb.com
*/
public class HeaderHandlerResolver implements HandlerResolver {
public List getHandlerChain(PortInfo portInfo) {
List handlerChain = new ArrayList();
HeaderHandler hh = new HeaderHandler();
handlerChain.add(hh);
return handlerChain;
}
}
Finally we need to add the handler resolver to our web service client class.
JavadbWebServiceService service = new JavadbWebServiceService();
HeaderHandlerResolver handlerResolver = new HeaderHandlerResolver();
service.setHandlerResolver(handlerResolver);
JavadbWebService port = service.getJavadbWebServicePort();
//Call web service
String currentTime = port.getTime();
System.out.println("Current time is: " + currentTime);
