ClassCastException in JMS ConnectionFactory lookup in JNDI.

[Subash Karuppaiah]

am new to Queues. I had setup my queue in JBOSS 5.1 EAP and now while trying to inject in tho the queue am getting a ClassCastException (in lookup of JNDI), I use flex on my front end and use Springframework for flex. When injected into the queue using quartz job it runs well and good. The quartz job is a separate project and has nothing to do with flex and spring.

I read over some where that this could be a jar issue, I had JMS jars in my spring and i tried removing, replacing all types of jars, no luck.

// Step 1. Create an initial context to perform the JNDI lookup.

			InputStream in = this.getClass().getResourceAsStream(
					"/clv2.properties");
			Properties configProp = new Properties();
			configProp.load(in);
			IpAddress = configProp.getProperty("ipaddress");
			port = configProp.getProperty("port");
			inQueueName = configProp.getProperty("inQueueName");
			Properties props = new Properties();
			props.setProperty("java.naming.factory.initial",
					"org.jnp.interfaces.NamingContextFactory");
			props.setProperty("java.naming.factory.url.pkgs",
					"org.jboss.naming");
			// props.setProperty("java.naming.provider.url", host + ":" + port);
			props.setProperty("java.naming.provider.url", "localhost" + ":"
					+ 1099);
			// props.setProperty("java.naming.provider.url",
			// "16.181.233.61:1399");
			initialContext = new InitialContext(props);

			// Step 3. Perform a lookup on the Connection Factory
			QueueConnectionFactory cf = (QueueConnectionFactory) initialContext
					.lookup("/ConnectionFactory");
			Queue queue = (Queue) initialContext
					.lookup(/* "/queue/CLVInboundQueue" */inQueueName);
			// Step 4.Create a JMS Connection
			connection = (QueueConnection) cf.createConnection();

			// Step 5. Create a JMS Session
			session = (QueueSession) connection.createSession(false,
					Session.AUTO_ACKNOWLEDGE);

			// Step 6. Create a JMS Message Producer
			// MessageProducer producer = session.createProducer(queue);
			QueueSender queueSender = session.createSender(queue);
			TextMessage textMessage = session.createTextMessage(message);
			textMessage.setLongProperty("Rejected_Message_ID",
					rejected_Message_Id);
			/*
			 * BufferedReader reader = new BufferedReader(new
			 * InputStreamReader(ClassLoader.class.getResourceAsStream(file)));
			 * StringBuilder sb = new StringBuilder(); String line = null;
			 * 
			 * 
			 * while ((line = reader.readLine()) != null) { sb.append(line +
			 * "\n"); } String announcementmsg = sb.toString();
			 */
			commonlogger.info(textMessage);
			connection.start();
			// producer.send(session.createTextMessage(announcementmsg));
			queueSender.send(textMessage);

This is my piece of coding to inject into the queue. I get the Exception in "//Step 3. Perform a lookup on the Connection Factory" and this is my stack trace.

Any serious help would be appriciated as i need a very urgent solution. Thanks!!

Is this code in an app deployed to JBoss AS, or is it in a standalone app? If in an app deployed to JBoss AS, you probably have some JBoss JARs packaged with your app, remove them. If you are not sure which ones to remove, post the full list of JARs packaged with your app.

Hi Peter, Thanks a lot for your quick reply and your help. I had a geronimo-j2ee-management_1.0_spec-1.0.jar, I tried removing it and now my app runs well and Good. This isn't a standalone app, i had deployed it in JBOSS EAP 5.1 in default profile.

I knew its a jar issue, but never thought it would be this one and hence never tried with this one, so fool of me!!
