How to add a SOAP header using jax-ws

In this article I will add a security header to the soap request. So I will create a class implementing the interface SOAPHandler and I will override the method handleMessage:

@Override
    public boolean handleMessage(SOAPMessageContext context) {
        String prefixUri = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-";
        String uri = prefixUri + "wssecurity-secext-1.0.xsd";
        String uta = prefixUri + "wssecurity-utility-1.0.xsd";
        String ta = prefixUri + "username-token-profile-1.0#PasswordText";
        Boolean outboundProperty =
            (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outboundProperty.booleanValue()) {
            try {
                SOAPEnvelope envelope = context.getMessage()
                        .getSOAPPart().getEnvelope();
                SOAPFactory factory = SOAPFactory.newInstance();
                String prefix = "wsse";
                SOAPElement securityElem =
                        factory.createElement("Security",prefix,uri);
                SOAPElement tokenElem =
                        factory.createElement("UsernameToken",prefix,uri);
                tokenElem.addAttribute(QName.valueOf("wsu:Id"),"UsernameToken-2");
                tokenElem.addAttribute(QName.valueOf("xmlns:wsu"), uta);
                SOAPElement userElem =
                        factory.createElement("Username",prefix,uri);
                userElem.addTextNode("myUser");
                SOAPElement pwdElem =
                        factory.createElement("Password",prefix,uri);
                pwdElem.addTextNode("myPwd");
                pwdElem.addAttribute(QName.valueOf("Type"), ta);
                tokenElem.addChildElement(userElem);
                tokenElem.addChildElement(pwdElem);
                securityElem.addChildElement(tokenElem);
                SOAPHeader header = envelope.addHeader();
                header.addChildElement(securityElem);

            } catch (Exception e) {
                System.out.println("Exception in handler: " + e);
            }
        }
        
        return true;
    }

Now, I will add a simple call to this class in my implementation client:

service.setHandlerResolver(new HandlerResolver() {
            @Override
    public List<Handler> getHandlerChain(PortInfo portInfo) {
        List<Handler> handlerList = new ArrayList<Handler>();
        handlerList.add(new MySoapHandler());
        return handlerList;
    }
});
