JSTL - Variable not retrieving value
 

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.

Repeating the question doesn't encourage people to answer.

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

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

I started a new thread because I could not see my questions posted in
the group.

I get

${rowColor}

even

${rowColor}

odd

for following code -

<c:forEach var="list" items="${foundationAidBean.childInstitutions}"
varStatus="status">
<c:choose>
<c:when test='${(status.index)%2 eq 0}'>
<c:set var="rowColor" value="even" scope="page"/>
</c:when>
<c:otherwise>
<c:set var="rowColor" value="odd" scope="page"/>
</c:otherwise>
</c:choose>

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


</c:forEach>


So it looks my jree version is not correct.

j2se - 1.4.2
Oracle JDeveloper 10g

What version should I use for my El to work.
