setting String in scope (JSTL)

[andy wix <st...@hotmail.com>]

Hi,

I am trying to set a string variable in page scope and thought the following 
would work:

<c:set var="background" scope="page" value="tableLightColour"/>

I was hoping that I would then be able use the variable as in the following:

<tr class="${background}">

but it doesn't work.

If I just use:
<TR class="tableLightColour">

the css attributes are seen as expected.

regards,
Andy

Is EL working in template text in other JSPs in the same context? Do
you have a servlet 2.4 web app descriptor? Please see question 1 here

What does the generated HTML look like... do you see the literal
${background} in the HTML?  Are you using a JSP 2.0 container, so that you
expect expressions to be evaluated anywhere in the page?

If you're not using JSP 2.0, try this:  <tr class="<c:out
value='${background}'/>">
