Hello Everyone, On page 597 of HFSJ, it states that "There is more you have to know if you write this by hand - the whole document, for example, must be enclosed in a <jsp:root> tag (which includes some other stuff), and the taglib directives go inside the <jsp:root> opening tag, rather than as a <jsp:directive>.

On pg 763 & 801, Q6 of the final mock exam, You are asked which choices about a JSP document are correct (and choose all that apply).

A: A JSP document must have a <jsp:root> as its top element.

B: The following would be valid as the first line of a JSP document: <jsp:root xmlns:uri="http://java.sun.com/JSP/Page" version="2.0">.

I wont list all of the choices in the spirit of "not giving the book away for free", but I am not sure why A or B are incorrect answers. can someone please explain? Thanks.

Take a look at Sun's J2EE tutorial:

Creating a JSP Document

I'm definitely not claiming to be an expert, but if you look at their examples (especially the standard JSP converted to a JSP Document), it's clear that you are NOT required to have jsp:root as the top element.

Anyway - hope that gives you a start on it.

Daniel is right. Page 597 is in error (you should submit it to the errata).

The mock exam is correct. For further confirmation, see this:

Can someone explain why this option is wrong in the JSP Document:

B: The following would be valid as the first line of a JSP document: <jsp:root xmlns:uri="http://java.sun.com/JSP/Page" version="2.0">

The jsp prefix must always be bound to the JSP namespace: http://java.sun.com/JSP/Page

But, Is it an error to bound the JSP namespace "http://java.sun.com/JSP/Page" with a different prefix. Is the above option wrong, because of using the prefix "uri".
