Hello ,
I am pretty new to JMS World. I have small question I think you people will be able to answer this.

I have a JMS Server ( OpenJMS / ActiveMQ ...). QueueConnectionFactory and Queue can be registered in some JNDI Server located somewhere .. ( Assumption)


From the Stand Alone application is it possible to load the Initial context properties and get QueueConnectionFactory and Queue from JNDI?
After this I hope i will be able to send messages to this queue.

Thanks n regds

you have to create the context with the information of the server you are going to send messages to.

Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");//or another class you want to use that depens on the server
env.put(Context.PROVIDER_URL, "server_IP:port");//server ip and port
Context context = new InitialContext(env);

with this context you create the connection factory
QueueConnectionFactory qcf = (QueueConnectionFactory)context.lookup("JNDI/connectionFactory");

i hope this can help you.

 

 

Absolutely! See

My current code is:
env.setProperty(Context.PROVIDER_URL, "iiop://localhost:2809");
env.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");

InitialContext initCtx = new InitialContext(env);

System.out.println("Getting connection factory....");
// Finding the WAS QueueConnectionFactory
javax.jms.ConnectionFactory qcf = (javax.jms.ConnectionFactory) initCtx.lookup(JMSCF_JNDI_NAME);
System.out.println("qcf="+qcf);
// Finding the Queue Destination
Destination q = (Destination) initCtx.lookup(JMSQ_JNDI_NAME);


I am getting exception as:
