method factorialBeanId.getFactorial() (line 25) returns the factorial
for the number in factorialBeanId.
DESIGN GUIDE
Mixing a lot of Java code with HTML in a JSP page makes
the code difficult to read and to maintain. You should
move the Java code to a .java file as much as you can.
***End DESIGN GUIDE
Following the preceding design guide, you may improve the preceding
example by moving the Java code in lines 23–25 to the FactorialBean
class. The new FactorialBean.java and FactorialBean.jsp are given in
Listings 43.11 and 43.12.
