[jira] [Commented] (QPID-4238) Virtual hosts or queues with dots in
their names do not work
[ https://issues.apache.org/jira/browse/QPID-4238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439081#comment-13439081 ]

--------------------------------------
Hi Jakub,
I must admit to us having known about this defect for a while. It is as you have noticed related to the Commons Configuration usage, and as such is linked to the xml config files rather than an inherant limitation of the broker. Although I can't admit to having tried it (our users dont tend to use dots so it has never become a priority) the JMX/HTTP interfaces shouldnt present any such restriction (but obviously cant currently create virtualhosts...though it is coming).
We will take a look at the patch later in the week probably (a bit swamped at the moment, hence the 11pm reply) and apply it if all seems well. It's probably worth me mentioning that we are currently undertaking a long term project to rework the broker management and configuration, including removal of the XML configuration hopefully for 0.20, so this was getting resolved one way or the other, but thank you for the patch in the meantime :)

> The latest version of the Qpid Java broker seems to have a problem with the virtual hosts and queues containing a dot in their name. This is related to the way the virtualhosts.xml configuration file is designed. When a queue is defined, the <queue> tag contains only the <name> tag with the queue name and a tag named after the queue which contains additional details. E.g.
> <queue>
> <name>queue.with.dot.in.the.name</name>
> <queue.with.dot.in.the.name>
> <durable>true</durable>
> </queue.with.dot.in.the.name>
> </queue>
> Unfortunately the dots are also used as special characters when working with the configuration file - they are used as delimiters in the XML hierarchy. In order to use them in the tag names, they need to be escaped with additional dot (i.e. queue..with..dot..in..the..name instead of queue.with.dot.in.the.name - http://commons.apache.org/configuration/userguide-1.2/howto_xml.html). This escaping doesn't seem to be currently done on the broker. As a result, the dots cannot be used in virtual host names or in queue names, which might be unfortunate for some users.
