Re: JMS Client

[Nishant Joshi]

Thanks Ant,
I have composed client for WS Here is the snippet of the client....

-------------------------------------------------------------------------------------------------------------------------

public class HelloWorldClientImpl {

    @Reference
    protected HelloWorldService serviceA;

    public String sayHello(String name) {
     System.out.println("HelloWorldClientImpl.serviceA = "+serviceA);
        return serviceA.sayHello(name);
    }

}
-------------------------------------------------------------------------------------------------------------------------
@Remotable
public interface HelloWorldService {
    String sayHello(String name);
}

-------------------------------------------------------------------------------------------------------------------------
public class JMSClient {
 public static void main(String[] args) throws NodeException  {
  SCANode node = SCANodeFactory.createNodeWithComposite("client.composite");
  HelloWorldClientImpl client =
node.getDomain().getService(HelloWorldClientImpl.class, "HelloWorldClient");

  System.out.println(client.sayHello("World"));
 }

}

-------------------------------------------------------------------------------------------------------------------------

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
           name="RPCComposite">

    <component name="HelloWorldClient">
        <implementation.java class="helloworld.HelloWorldClientImpl"/>
        <reference name="serviceA" />
    </component>

    <reference name="serviceA" promote="HelloWorldClient/serviceA">
        <interface.java interface="helloworld.HelloWorldService" />
        <binding.jms
initialContextFactory="com.ibm.websphere.naming.WsnInitialContextFactory"
jndiURL="iiop://localhost:2809">
            <destination name="HelloWorldService"/>
            <response>
               <destination name="HelloWorldService"/>
            </response>
        </binding.jms>
    </reference>
</composite>

jndi.properties

# START SNIPPET: jndi

java.naming.factory.initial =
com.ibm.websphere.naming.WsnInitialContextFactory

# use the following property to configure the default connector
java.naming.provider.url = vm://localhost?broker.persistent=false

# use the following property to specify the JNDI name the connection factory
# should appear as.
#connectionFactoryNames = connectionFactory, queueConnectionFactory,
topicConnectionFactry
connectionFactoryNames = ConnectionFactory

# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
# queue.RequestQueue = RequestQueue
# queue.ResponseQueue = ResponseQueue
queue.HelloWorldService = HelloWorldService

# register some topics in JNDI using the form
# topic.[jndiName] = [physicalName]
#topic.MyTopic = example.MyTopic

# END SNIPPET: jndi


Here Service is deployed successfuly, i can test with hello.jsp....It was
working fine in WS.
Now when i run above code I m getting "HelloWorldClientImpl.serviceA = null"
and gettign NPE....
I m using "HelloWorldService" for both Request and Response queue...

any idea ?

Thanks
