直接バインディング起動APIの使用例

この項では、APIの使用方法について説明します。接続パラメータを設定し、直接バインディングによってSOAコンポジット・アプリケーションを起動する方法、および直接バインディング起動を起動するようにメッセージ・オブジェクトを変更する方法を示します。

// The JNDIDirectConnectionFactory can be used to establish SOA instance
// connections for exchanging messages over the direct binding.
DirectConnectionFactory dcFactory = JNDIDirectConnectionFactory.newInstance();

// Connections are created based on the configuration, which is a map of standard
// naming properties, which will be used for the underlying connection lookup.
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(Context.INITIAL_CONTEXT_FACTORY, jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, "t3://HOST:PORT");
properties.put(Context.SECURITY_PRINCIPAL, USERNAME); 
properties.put(Context.SECURITY_CREDENTIALS, PASSWORD);
DirectConnection conn =
    dcFactory.createConnection("soadirect:/default/MyComposite!1.0/MyService",
                               properties);

// Messages are created using the MessageFactory
// Message objects are subsequently modified to be used for an invocation.
Message<Element> request = XMLMessageFactory.getInstance().createMessage();

// Define a Map of WSDL part names to matching XML Element objects
Map<String, Element> partData;

Payload<Element> payload = PayloadFactory.createXMLPayload(partData);
request.setPayload(payload);

// One-way invocation
conn.post("onewayoperation", request);

// Request-reply invocation
Message<Element> response = conn.request("requestreplyoperation", request);

Hashtable jndiProps = new Hashtable();
jndiProps.put(Context.PROVIDER_URL, "t3://" + HOST + ':' + PORT);
jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,
              "weblogic.jndi.WLInitialContextFactory");
jndiProps.put(Context.SECURITY_PRINCIPAL,USERNAME); 
jndiProps.put(Context.SECURITY_CREDENTIALS, PASSWORD);
Locator locator = LocatorFactory.createLocator(jndiProps);
CompositeDN compositedn = new CompositeDN(domainName, compositename, version);
String serviceName = "HelloEntry";
DirectConnection conn = locator.createDirectConnection(compositedn, serviceName);
