How to Invoke an SDO-Enterprise JavaBeans Service

To invoke an SDO - Enterprise JavaBeans service from Enterprise JavaBeans, you must use the client library. Follow these guidelines to design an Enterprise JavaBeans client.

• Look up the SOAServiceInvokerBean from the JNDI tree.

• Get an instance of SOAServiceFactory and ask the factory to return a proxy for the Enterprise JavaBeans service interface.

• You can include a client side Enterprise JavaBeans invocation library ($FMW_HOME/soa/soa/modules/oracle.soa.fabric_11.1.1/fabric-client.jar or the fabric-runtime.jar file located in the Oracle JDeveloper home directory or Oracle WebLogic Server) in the Enterprise JavaBeans client application. For example, the fabric-runtime.jar file can be located in the JDev_Home\jdeveloper\soa\modules\oracle.soa.fabric_11.1.1 directory.

  If the Enterprise JavaBeans application is running in a different JVM than Oracle SOA Suite, the Enterprise JavaBeans application must reference the ejbClient library. The code that follows provides an example.

  You must specify the complete path of the service ID with the MyTestEJBService parameter of serviceFactory.createService (for example, "default/MyTestProject!1.0/MyTestEJBService"). If the complete path is not specified, you receive an EJBException- Could not locate the service error.

Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY,
 "weblogic.jndi.WLInitialContextFactory");
        props.put(Context.PROVIDER_URL, "t3://" + HOSTNAME + ":" + PORT);
        InitialContext ctx = new InitialContext(props);
        SOAServiceInvokerBean invoker =
                (SOAServiceInvokerBean)
 ctx.lookup("SOAServiceInvokerBean#oracle.integration.platform.blocks.sdox.ejb.api.
SOAServiceInvokerBean");

        //--  Create a SOAServiceFactory instance
        SOAServiceFactory serviceFactory = SOAServiceFactory.newInstance(invoker);

        //--  Get a dynamice proxy that is essentially a remote reference
        HelloInterface ejbRemote =
 serviceFactory.createService("complete_path/MyTestEJBService", HelloInterface.class);

        //--  Invoke methods
        Item item = (Item) DataFactory.INSTANCE.create(Item.class);
        item.setNumber(new BigInteger("32"));
        SayHello sayHello = (SayHello)
 DataFactory.INSTANCE.create(SayHello.class);
        sayHello.setItem(item);

        SayHelloResponse response = ejbRemote.sayHello(sayHello);
        Item reply = response.getResult();
