When I use this code inside the table,the table content is not displayed.Please help!

did you declaired jstl? i.e. `<%@ taglib prefi x=”c” uri=”http://java.sun.com/jsp/jstl/core” %>` — Laurence Geng, Aug 26 '14 at 04:54
Better use enums instead of chars. You can compare enums the "normal" way (exactly like as in your current attempt). Here's a more elaborate answer in JSF context: http://stackoverflow.com/questions/14454261/rendered-attribute-not-working-on-a-character-property/14457612#14457612 — BalusC, Aug 26 '14 at 05:19

Issue is EL supports both double and single quoted Strings. So 'U' is taken as String, not char. To resolve the issue, you can use charAt(0) method on that String:

<c:if test="${record.type eq 'U'.charAt(0) }">Planned</c:if>

This works for me:

`<c:if test="${'U'.toString() eq 'U'}">demo</c:if>`

It works for me since instead of first 'U', I was getting the list of Characters. So the type should be converted to String first.)

check the value of ${record.type} print it on jsp

becuse

<c:if test="${'U' eq 'U'}">demo</c:if>

it works for me in jsp

or if you have some version conflict then

try below one it may help

<c:if test = "${record.type == 'U'}">demo</c:if>

but make sure the value of ${record.type}

not working for comparing characters
