JNDI lookup for ConnectionFactory and destination failing

I am trying to write a simple JMS client (external) which will lookup the
ConnectionFactory and destination using JNDI and send a message to the
destination without using any 3rd party or ActiveMq API's.
For this I customized loanbroker example by removing all the classes except
for JMSClient and 
LoanBroker.

This is the snippet of my JMSClient 

 Properties props = new Properties();
            props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.activemq.jndi.ActiveMQInitialContextFactory" );
            props.put(Context.PROVIDER_URL, "tcp://localhost:61616/"); 
            jndiContext = new InitialContext(props);  
         connectionFactory = (ConnectionFactory)
jndiContext.lookup("ConnectionFactory");
             dest = (Destination) jndiContext.lookup("jndiEx.source");
            connection = connectionFactory.createConnection();
           Session session = connection.createSession(false,
           Session.CLIENT_ACKNOWLEDGE);
           MessageProducer producer = session.createProducer(dest);
           producer.send(session.createTextMessage("<message>Hello,
world!</message>"));

I have configured the same destination name in servicemix.xml file. I
successfully built and deployed this SA into Servicemix. When I run, the
follow exception is thrown

JNDI API lookup failed: javax.naming.NameNotFoundException: jndiEx.source
javax.naming.NameNotFoundException: jndiEx.source
    at
org.apache.activemq.jndi.ReadOnlyContext.lookup(ReadOnlyContext.java:215)

1. Please help me out to resolve this issue?
2. Is it possible to use SpringInitialContextFactory and implement the same?
3. If I have to use jndi.properties to configure ConnectionFactory and
destination name as per http://activemq.apache.org/jndi-support.html, then
where do I need to keep this property file so that it is used only for this
example.

Thanks in advance

Hi,

You must ensure that all component that your're using will propagate the 
correlation id.
Most of the components have support for this, but i think this is not 
sure for all.

We've had the same problem, with spagic development where we use the 
correlation ID to
support the concept of Process and Process Instance, and in general when 
we've found a component
that don't support correlation ID propagtion we've raised a JIRA and a 
patch for this.

By the way i've not clear your flow, but as i know all component you 
need support that feature.

Hi,
i have to keep a correlation between SU, ie i want to have one id for 
all su of my pattern (flow)
My flow consist to :

HTTP > JMS > EIP > XSLT >  JMS > HTTP

So how to use the correlationID and how to pass it in NMR messages ?
