Roan commented on ARTEMIS-322:
------------------------------
If you see on ActiveMQSession, in the beginning there is:
{code}
private ActiveMQTopic lookupTopic(final String topicName, final boolean
isTemporary) throws ActiveMQException {
ActiveMQTopic topic;
if (isTemporary) {
topic = ActiveMQDestination.createTemporaryTopic(topicName);
}
else {
topic = ActiveMQDestination.createTopic(topicName);
}
AddressQuery query = session.addressQuery(topic.getSimpleAddress());
if (!query.isExists()) {
return null;
}
else {
return topic;
}
}
{code}
If you see, my code should go throw to the temporary topic condition and when
the session called for the addressQuery the return is not with the values I'd
created. There is a problem on that to use the topic as I'm using. I'm not
using configuring on broker.xml on my Artemis. I want to use the temporary
topic.
