After skimming through the chapter-3 of the book, I found out that there is a difference between EL Activating element in jsp-property-group of the book and that of the JSP Specification... Is the container using in the book accept the deployment descriptor specified as el-enabled, not "el-ignored" as in the spec? Could any of the authors answer to this issue? I've extracted some part from the chapter-3 of the book here...
el-enabled The el-enabled element configures if the JSP EL is available for use on the specified JSP. A value of true enables EL use. A value of false disables it. The functionality is analogous to the page directive’s isELEnabled attribute.
It's either a bug, or (and I can't rememeber this exactly) it could be that as the book was finished ahead of the spec that the specification changed during the writing of the book and we missed this one. You can report this as a bug at the book's support site

Thank you very much for your response, Mr.Kevin... I just reported that errata at the site u provide... After reading that portion again, I found out one more errata about scripting-enabled element of the same jsp-property-group... It's also the same error as I mentioned above... In the JSP 2.0 Spec, that element is mandated as scripting-invalid and we can set it to be true, if we do not want scriptlets in the JSP pages... But the book explained it differently... The book said that if scripting-enabled is set to be true, we can use scriptlets in JSP pages... Just my 2 cents...
