Question on Issue with fmt:formatNumber tag of jstl

Question

Hi,
We have a web application that uses struts framework. In the action class,i am setting an attribute of request object like
request.setAttribute("Val",new Double(11.25489));
I am using jstl fmt:formatNumber function in the jsp page to format the value to 2 decimal places.
<fmt:formatNumber value="${Val}" maxFractionDigits ="2" />
When i access the jsp page,there is no display of anything.
If i access using <c:out value="${Val}"/> ,it does print the value.
Interestingly,tomcat does not generate any corresponding java file in its work area.
Any clues...anybody ?

Answer 1

Ok you are setting the value in request scope?
How does the control transfer from the Struts Action to your JSP page?
Check the struts-config to see if that forward is configured as a "redirect". If that is so, your request attribute would be lost, because a redirect causes a new request.
The following code prints out all request attributes that are currently in scope.
It might help checking to see if your "Val" is in scope or not.
Request scope attributes:
<table border="1">
<c:forEach var="attr" items="${requestScope}">
  <tr><td><c:out value="${attr.key}"/>a</td><td><c:out value="${attr.value}"/></td></tr>
</c:forEach>
</table>Cheers,
