Guiseppe,
To connect to ActiveMQ from your simple visual application, the easiest
solution with JNDI would probably be to leverage ActiveMQ's built-in
JNDI support. Have a look at
http://activemq.apache.org/jndi-support.html for more information.

<property name="brokerURL"

</bean>
</property>
</bean>
</beans>
Now, how can I send messages to that component? I tried the following code,
but a NoInitialContextException is raised. Consider I have never used JNDI,
so I wrote a simple visual application with a textArea and a button and put
the following code in the action performed by the press of the button,
nothing else. The code is taken from a Sun tutorial and modified.
private void sendMessage() {
/*
* Create a JNDI API InitialContext object if none exists yet.
*/
try {
jndiContext = new InitialContext();
} catch (NamingException e) {
System.out.println("Could not create JNDI API " + "context:
"
+ e.toString());
System.exit(1);
}
/*
* Look up connection factory and queue. If either does not
exist, exit.
*/
try {
queueConnectionFactory = (QueueConnectionFactory)
jndiContext
.lookup("ConnectionFactory");
queue = (Queue) jndiContext.lookup(queueName);
} catch (NamingException e) {
System.out.println("JNDI API lookup failed: " +
e.toString());
System.exit(1);
}
/*
* Create connection. Create session from connection; false
means
* session is not transacted. Create sender and text message.
Send
* messages, varying text slightly. Send end-of-messages
message.
* Finally, close connection.
*/
try {
queueConnection =
queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
message = queueSession.createTextMessage();
message.setText(msgTxt.getText());
queueSender.send(message);
// for (int i = 0; i < NUM_MSGS; i++) {
// message.setText("This is message " + (i + 1));
// System.out.println("Sending message: " +
message.getText());
// queueSender.send(message);
// }
/*
* Send a non-text control message indicating end of
messages.
*/
// queueSender.send(queueSession.createMessage());
} catch (JMSException e) {
System.out.println("Exception occurred: " +
e.toString());
} finally {
if (queueConnection != null) {
try {
queueConnection.close();
} catch (JMSException e) {
}
}
}
}

Hi all. It's the first time I use JMS and JNDI... what is
jndiConnectionFactoryName? How to use it? I tried to deploy a simple
service unit:
<beans xmlns:jms="http://servicemix.apache.org/jms/1.0";
xmlns:beppe="http://giuseppe.org";>
<!-- START SNIPPET: consumer -->
<jms:endpoint service="beppe:jms-service"
endpoint="jms"

role="consumer"
destinationStyle="queue"
jmsProviderDestinationName="validateQueue"
jndiConnectionFactoryName="ConnectionFactory"
defaultMep="http://www.w3.org/2004/08/wsdl/in-only"; />
<!-- END SNIPPET: consumer -->
</beans>
but I get the following error, dependant on jndiConnectionFactoryName:
