Subject Artemis 2.0: How to get the list of Queues and Topics from a server? (Fails in 2.0 with v1.5.3 code)
Date Wed, 22 Mar 2017 18:01:31 GMT
With Artemis v1.5.3, to retrieve the list of queues and topics, I was
using this code (inspired from the example)

Queue managementQueue = ActiveMQJMSClient.createQueue("");
Session sessionJMS = jmsConnection.createSession(false,
QueueRequestor requestorJMS = new QueueRequestor((QueueSession)
sessionJMS, managementQueue);
Message m = sessionJMS.createMessage();
JMSManagementHelper.putAttribute(m, ResourceNames.JMS_SERVER,
"queueNames"); // "topicNames" for topics
Message r = requestorJMS.request(m);
Object q = JMSManagementHelper.getResult(r);

If I run this code from a client with the v1.5.3 jars to a v2.0.0 server I got:
An exception on the server:

Caused by: java.lang.IllegalArgumentException: AMQ119067: Cannot find
resource with name jms.server
        ... 30 more

And an exception on the client:
java.lang.IndexOutOfBoundsException: readerIndex(22) + length(98)
exceeds writerIndex(116): UnpooledDuplicatedByteBuf(ridx: 22, widx:
116, cap: 451, unwrapped: UnpooledUnsafeHeapByteBuf(ridx: 439, widx:
451, cap: 451))

I tried to update the client jars to v2.0.0. In v1.5.3, the
"ResourceNames.JMS_SERVER" variable exists with value "jms.server", in
v2.0.0, The ResourceName has benne totally changed and no "JMS_SERVER"
variable anymore (and no "SERVER" lookalike variable..).

So the question are
- how to retrieve the list of Queues and Topics from an Artemis v2.0.0 server?
- is there a migration/upgrade guide to upgrade from 1.5.x to 2.0.x?
- or a least is there a list of "deprecated/removed/changed" features
from v1.5.x to 2.0.x?
