JSTL c:set problem

So for some reason when I set variables they just... don't exist O.o

Some test code I wrote:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix = "c"%>


<c:set var="period" value="1" scope="session" />
<c:out value="${param.period}" />


This just shows a blank page. I was using something similar in different code earlier and at one point I printed the variable, which worked, but now it won't print anything anymore, and when I use it in a constraint I get incorrect results. I can't see any syntax errors. Anybody know whats going on?

Look like the uri value does not return xml file anymore.

I think it is better for you to create one jstl xml file.

Thanks! Can you elaborate on how to do that?

Still confused, any more help would be great...

Have a read here.
The URI is dependent on the version of the library you are using (see link).
It's a marker, not a real location, used by the library.

Thanks for that Tolls. I'm not sure if that's the problem though, since my jstl sql statements are working fine.

Also I added the following line to my code and it outputted 5 like it should:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix = "c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix = "sql"%>

<c:set var="period" value="1" scope="session" />
<c:out value="${param.period}" />
<c:out value="${3+2}" />


Then again I could have just misunderstood the link you sent me >.>

Actually, is that first c:out correct?
You've just stored "period" in your session.
Shouldn't that be "sessionScope.period" then?

Also, as the link I posted says, you don't need to use c:out for EL.
The EL will be translated anyway.

Oh... that worked! Apparently I need to brush up on my syntax >.>

Thanks!

I should have spotted that sooner.
I got distracted by jing-yi's point, which turned out to be a wrong turn...:)

Heh, I probably should have spotted it myself. ^_^ Thanks again
