hi,
yes JSTL has some advantages over Struts tags.
JSTL tags really help you write 0 scriptlet code.
Also, the JSTL tags are more readable and easy to understand.
e.g. <c:if> is much simpler than <logic:equal>
In fact logic:equla just allow you to compare for equality/inequality. Whereas in c:if you can specify
any condition just as in any backend language.
It also facilitates many mathematical operations.
e.g. consider example, where you want are dispalying list (html table) and you want to use alternate CSS for even and odd row. How can you do it with strutsWITHOUT using scriptlets.
but with JSTL you can do so,:
Put the following code inside <logic:iterate> or i'll suggest <c:forEach> tag..:))
<c:if test="${rowIndex%2 == 0}">
                <c:set var="cssClass" value="datacelltwo"/>
           </c:if>
           <c:if test="${rowIndex%2 != 0}">
                <c:set var="cssClass" value="datacellone"/>
           </c:if>
           <c:set var="rowIndex" value="${rowIndex+1}"/>
