Hey Gaurav,
Whay you indicate seems as simple as:
<c:forEach var="item"
items="${some-variable-set-by-request-setattribute}">
<c:if test="${item.selected}">
<c:out value="${item}"/>
</c:if>
</c:forEach>
What you might want to do is read the Sun JSTL Specification. It provides an
excellent reference to how the tags work and is very readable. Check it out
at:

Grtz,
Martin

Hi Martin,
Thanks...
But probably this is not what I am looking for. Or may be I got you
wrong.
Snippets will make it once-for-all includes. But the include is dynamic.
It is known only at runtime.
So, I would like to have something like the following:
<tag:selector var="item" items="somevar">
<tag:if var="$item.selected">
<tag:render item="$item/>
</tag>
</tag:selector>
One way would be to use JSP-snippet:
<%
for(int i = 0; i < somevar.size(); i++)
{
MyItem item = somevar.get(i);
if(item.isSelected())
{
item.render(whatever, parameter, list, required, like,
context, request, response, servlet, etc);
}
}
%>
Can you provide in more details of what you meant by HTML Snippets?
Cheers,
Gaurav
