selectors work on any message property. have a peek at the tests: http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/selector/SelectorTest.java?view=markup
and http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/JmsTopicSelectorTest.java?view=markup to see examples of the the syntax. selectors work in the same manner for browsers. The only thing to note is that selectors are run in memory, so you may need to configure a large maxPageSize via a destination policy entry if you have sparse selectors as the maxPageSize determines how many messages are retained in memory pending dispatch, An alternative to selectors is to use virtual destinations such that selected messages are redirected to their own destination.
