次のコードサンプルは,Serverクラスに加える変更を示します。AccountManagerPOATieのインスタンスを生成するための追加手順に注意してください。
import org.omg.PortableServer.*; public class Server { public static void main(String[ ] args) { try { // Initialize the ORB. org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,null); // get a reference to the rootPOA POA rootPOA = POAHelper.narrow( orb.resolve_initial_references("RootPOA")); // Create policies for our persistent POA org.omg.CORBA.Policy[ ] policies = { rootPOA.create_lifespan_policy( LifespanPolicyValue.PERSISTENT) }; // Create myPOA with the right policies POA myPOA = rootPOA.create_POA("bank_agent_poa", rootPOA.the_POAManager(), policies); // Create the tie which delegates // to an instance of AccountManagerImpl Bank.AccountManagerPOATie tie = new Bank.AccountManagerPOATie( new AccountManagerImpl(rootPOA)); // Decide on the ID for the servant byte[ ] managerId = "BankManager".getBytes(); // Activate the servant with the ID on myPOA myPOA.activate_object_with_id(managerId,tie); // Activate the POA manager rootPOA.the_POAManager().activate(); System.out.println("Server is ready."); // Wait for incoming requests orb.run(); } catch (Exception e){ e.printStackTrace(); } } }
