Changing the xmlns was correct, this resolved your namespace problem. The next
issue is that you're trying to install an instance of BrokerFilter instead of
BrokerPlugin. The broker plugin uses the installPlugin method to hook in the
BrokerFilter, so you should use this class:
http://people.apache.org/~gtully/staging-sites/activemq-5.2.0/maven/5.2.0/activemq-core/apidocs/org/apache/activemq/plugin/DiscardingDLQBrokerPlugin.html
. In other words:
class="org.apache.activemq.plugin.DiscardingDLQBrokerPlugin"
I assume you used the example here:
http://issues.apache.org/activemq/browse/AMQ-1892 (that's the only reference I
could find) . That means this example is wrong, would you mind making a comment
and updating it after you confirm that this fixes the problem?
