logic tags in JSTL?

[John Holme]

Can JSTL or built-in jsp tags be used to implement functionality similar to the Struts logic tags? Here's what I want to do...
I've set a bean as a request attribute (called "featureBean"), which I'm accessing in my jsp via the jsp:useBean tag. I want to make a chunk of html dependent on the value of a boolean field of "featureBean".
I can't do this using a jsp:getProperty tag, because it's not a body tag. I could use an expression like featureBean.getBoolean() in a scriptlet; but I'm trying to avoid jsp scriptlets.
Can I do this using built-in jsp tag functionality or a jsp expression? Can I do it using JSTL?
Thanks for your thoughts!

The if tag of JSTL has a test parameter. You can use JSTL's expression language in that parameter to access the properties of your bean like so:
<c:if test="${bool.isTrue}">

how can I map my bean property to the expression language?

Sure:
<c:if test='${featureBean.value}'>
optional html goes here
</c:if>
(assuming your boolean variable is named value and not boolean)

They are stored in either the page, request, session, or application scope.
