Hey Gennady, how are you? I have seen one post here where they said they got 1 question on filters. As far as Listeners, yes there will be, probably one for them in the web.xml file. Some other posts that recently took the test said they saw no questions on filters. Mark
Yes. They do test on Servlet API 2.3 and JSP 1.2. The stuff that was ADDED in 2.3 is not given much importance except Listeners. (you might also consider reading filters atleast once. I did not have any filter question though). Be careful on the stuff CHANGED from 2.2 to 2.3 (such as a constant in tag handler). I did not see any wrapper question as well.
