Why would I get this ClassCastException then? I do have a
jndi.properties in a JNDI.jar that's in my classpath and here's it's
contents
# use the following property to configure the default connector
#java.naming.provider.url = tcp://localhost:61616
java.naming.provider.url = vm://localhost
#connectionFactoryNames=ConnectionFactory
# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.QREQ = QUEUE_NAME
When I took at look at the source to
jndi.ActiveMQInitialContextFactory I didn't see any support for
jndi.properties so is this something that's support to
InitialContextFactory?
The classcastexception happens in the following code
Object obj = context.lookup(getQueueConnectionFactory());
if (!(obj instanceof QueueConnectionFactory)) {
String msg = "QueueConnectionFactory expected, but
got "
+ obj == null ? "null" : obj.getClass().getName();
LOGGER.fatalError(msg);
throw new IllegalStateException(msg);
}
QueueConnectionFactory factory = (QueueConnectionFactory)
obj;
Queue queue = (Queue) context.lookup(getSendQueue());
The ContextFactory lookup goes ok but for some reason the queue lookup
returns an ReadOnlyContext
and not a Queue.

I'm trying to get JMeter working with the JMSSampler and I keep
getting a classcastexception when it does the lookup

java.lang.ClassCastException:
org.apache.activemq.jndi.ReadOnlyContext
cannot be cast to javax.jms.Queue
Yes - if it can find it on its classpath - see
http://activemq.apache.org/jndi-support.html
cheers,
