 Line 23 : This outputs the name of the author using expressions.
 Line 50 : This shows that it is not possible to output the name of the author using
a JSP standard action.
 Line 60 : This outputs the name of the author using EL.
Figure 3-7 illustrates what you will see when you run this application ( http://localhost:8080/
chapter03/book ). Essentially, it is just not possible to display the value of the name property of Author
using a standard JSP action; scripting elements would have been the only way to do it, had it not
been for EL.
