Re: switching to struts-el

[Bill Siggelkow]

Thanks for the mention, Ted.  As far as the Struts-EL calculator, the 
calculation is actually done by the CalcAction (Calc.do) -- not a helper 
bean.  The calculation could have been done inline (using EL in the 
<c:out>) as with the JSTL calculator; however, in this case, I have the 
action to which the form is submitted perform the calculation and place 
the value into request scope.

Bill, 

Your presentation, mentioned in another thread, is also very helpful.

Towards the end, you show a simple calculator implemented as JSP, Struts, Struts-EL, and JSTL. On page 33, the Struts-EL uses a "helper bean" to do the arithmetic. The others do the addition inline. Why is it done differently for Struts-EL?

I feel your pain, Dean :) With the relatively rapid changes in
Java/Web technology it is difficult for print material to keep up.
I really liked JSTL in Action -- however, you may want to read the
JSTL 1.1 spec to pick up the new features.  I put out a JSTL Quick
Reference that you might find useful at
