WebService with Apache CXF and custom headers

cxf, java, spring-ws

Solution

Well I implement a Handler, first I downloaded the examples from CXF and modified the logging Handler, and it works.

The configuration of spring :

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

    <jaxws:endpoint
        id="encuestas"
        implementor="com.webservice.EncuestasImpl"
        address="/Encuestas">
    <jaxws:handlers>
            <bean class="com.webservice.HeaderHandler"/>

        </jaxws:handlers> 

    </jaxws:endpoint>

And the code this is the code for the handler.

/*

package com.webservice;

import java.io.PrintStream;
import java.util.Map;
import java.util.Set;

import javax.xml.namespace.QName;
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;

/*
 * This simple logical Handler will output the payload of incoming
 * and outgoing messages.
 */
public class HeaderHandler  implements SOAPHandler<SOAPMessageContext> {

    private PrintStream out;

    public HeaderHandler() {
        setLogStream(System.out);
    }

    protected final void setLogStream(PrintStream ps) {
        out = ps;
    }

    public void init(Map c) {
        System.out.println("LoggingHandler : init() Called....");
    }

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

    public boolean handleMessage(SOAPMessageContext smc) {
        System.out.println("LoggingHandler : handleMessage Called....");
        logToSystemOut(smc);
        return true;
    }

    public boolean handleFault(SOAPMessageContext smc) {
        System.out.println("LoggingHandler : handleFault Called....");
        logToSystemOut(smc);
        return true;
    }

    // nothing to clean up
    public void close(MessageContext messageContext) {
        System.out.println("LoggingHandler : close() Called....");
    }

    // nothing to clean up
    public void destroy() {
        System.out.println("LoggingHandler : destroy() Called....");
    }

    /*
     * Check the MESSAGE_OUTBOUND_PROPERTY in the context
     * to see if this is an outgoing or incoming message.
     * Write a brief message to the print stream and
     * output the message. The writeTo() method can throw
     * SOAPException or IOException
     */
    protected void logToSystemOut(SOAPMessageContext smc) {
        Boolean outboundProperty = (Boolean)
            smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

        if (outboundProperty.booleanValue()) {
            out.println("\nOutbound message:");
        } else {
            out.println("\nInbound message:");
        }

        SOAPMessage message = smc.getMessage();




        try {
            message.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");
            message.writeTo(out);
            out.println();
        } catch (Exception e) {
            out.println("Exception in handler: " + e);
        }
    }
}

Note: that in the try I use `MessageContext.MESSAGE_OUTBOUND_PROPERTY` like Justin suggested.
