I have declared a variable rowcolor. If i use c:out that works. So
following two line of code is worknig.

<c:set var="rowColor" value="even" scope="page"/>
<tr class="<c:out value='${rowColor}'/>">

But when i use below coe it does not work.
<tr class="${rowColor}">
HTML spits out <tr class="${rowColor}"> as this
where as in c:out version it spits out <tr class="even">

Can any body pls tell me why <tr class="${rowColor}"> is not working.

From your first posting of this question, in "JSTL - $variablename not working",

Please let me know why below code is ot worknig and how to solve it.

<c:choose>
     <c:when test='${(status.index)%2 eq 0}'>
      <c:set var="rowColor" value="even" scope="page"/>
    </c:when>
  </c:choose>

<tr class="${rowColor}">

I get "${rowcolor}" in html for above line of code -- <tr class="$
{rowColor}">

I doubt it very much. I would believe you got "${rowColor}", though.

How is var="rowColor" set when the c:when condition fails?

Your question would be easier for us to approach if you posted an SSCCE.

You might be working with a version of JEE that only accepts EL in JSTL
constructs. Since <tr> is not a JSTL tag, it wouldn't parse the EL
expression in that scenario.

Compare
<p>${rowColor}</p>
<p><c:out value="${rowColor}"/></p>

in a test page (which you could post as an SSCCE). What do you get?

What is your platform?

Just out of curiosity, why did you start a new thread on the same question?
