Listing 5.1A, the web.xml has the wrong schemaLocation.

It has: xsi:schemaLocation="http://java.sun.com/dtd/web-app_2_3.dtd"

Shouldn't it be: xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" ???

You bring up a very good point. Javid and I have been using the 2.3, 2.4, and 2.5 JSP spec when building the examples, and they should probably all be 2.5. This is what happens when you write a book over the course of 1-1/2 years, and you use older code as templates for the examples, and the specs change along the way. Thanks for pointing it out.
