Hi Ranchers, I'm just confused with this line in Headfirst Servlets and Jsp <c:set> pg.457.

It say's here that:

"You can never have both the "var" and "target" attributes in a <c:set>."

But when I try this block of codes it's working fine.

Here is the servlet doGet:


Here is the Jsp:


Hi ranchers hope you could help me!

Thanks!

The JSP specification does not say anything in this case. There are only four syntaxes expected :

If it's not one of these, I guess that it's up to the container to decide what to do.

Hi guys,

Hmmm.. Does this mean that Headfirst Servlets and Jsp Rules regarding <c:set> is with an older version of jstl?

I am wondering on what rules to follow for the exam SCWCD 5..


Quite confused..

But anyway thanks for the reply guys.

Hi Neil,

No, they are correct: don't use both of them at the same time (although you can)

I am wondering on what rules to follow for the exam SCWCD 5..


The exam always follows the official specifications which means one of the four possibilities that Christophe gave you

Regards,
Frits
