Java – how add Message context headers to apache axis 2 Java

axis2javajax-wsweb serviceswebservice-client

I am working on web services. I want to know how do we add headers to SOAP request in JAX-WS type web services.

Consider My header like this.

    Map<String, List<String>> headers = new HashMap<String, List<String>>();
    headers.put("Username", Collections.singletonList("aaaa"));
    headers.put("Password", Collections.singletonList("aaaa"));

I have stub object in my client class. I am using Apache Axis 2. All the classes are automatically generated.

SimpleSTub stub = new Simplestub();

I want to add this header information in client.

MessageContext.HTTP_REQUEST_HEADERS, headers

Edit

The actual implementation in a normal class found as

private static final String WS_URL = "http://localhost:9999/ws/hello?wsdl";

public static void main(String[] args) throws Exception {

URL url = new URL(WS_URL);
QName qname = new QName("http://ws.mkyong.com/", "HelloWorldImplService");

Service service = Service.create(url, qname);
HelloWorld hello = service.getPort(HelloWorld.class);

/*******************UserName & Password ******************************/
Map<String, Object> req_ctx = ((BindingProvider)hello).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);

Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Username", Collections.singletonList("mkyong"));
headers.put("Password", Collections.singletonList("password"));
req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
/**********************************************************************/

System.out.println(hello.getHelloWorldAsString());

Can any one tell how to achieve this.

Thanks.

You're sort of on your way to the solution with what you already have. The most basic way to achieve this is

  1. Within your client code, obtain a reference to the MessageContext through the BindingProvider on your SimpleStub

    Map<String,Object> context = ((BindingProvder)stub).getRequestContext()
Map<String,List> headers = context.get(MessageContext.HTTP_REQUEST_HEADERS)

  2. Update the map and stuff it back in the request context object

    context.put(MessageContext.HTTP_REQUEST_HEADERS,headers)

    The above is all well and good. If however you're trying to do what I presume is add authentication parameters, the recommended way is

    context.put(BindingProvder.USERNAME_PROPERTY,"username");
context.put(BindingProvder.PASSWORD_PROPERTY,"password");
