Does the order of Listeners and Servlets matter in DD ?

I came across this question (in italics below) on JavaRanch Mock exam and as per it the order does matter. But on Pg 174 of HFSJ, I see a DD with "listener" element after "servlet" element. Any thoughts ??


The above entry in the Deployment Descriptor(DD) will result in which of the following?

Answer: The webapp will not be loaded due to a parse exception of the DD.

Explanation: The ordering of the DD is listener then servlet.

The question in JavaRanch targes Servlet spec 2.3. In 2.3, <listener> must appear before <servlet> element in deployment descriptor. As of 2.4, the order of <servlet> and <listener> does not matter.
Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
