Hi there, here is my big problem today. I am using JSTL in some JSPs.
SInce this is a struts project, I would
like to keep my views totally separated from the Java APIs. For this
reason, I need your advice about the
most elegant to compare a given object "type" (an int constant) with the
possible values using the COSTANT name,
instead of the corresponding int.
The API defines the types of my object as:
public interface ContentType {
public static final int FOLDER = 1;
public static final int URL = 2;
}
in my JSP I have (loop over collection of items with getType() returning
the type int)
<c:forEach var="item" items="${content_list}">
<c:choose>
<c:when test="${item.type == 2}">
<a href="${item.value}"><c:out value="${item.name}"/></a>
</c:when>
:
I would like to do something like:
a) <c:when test="${item.type == ContentType.URL}">
This won't work. I could hack it around with a scriptlet and an import
at the top of my JSP, but that seems to me like
violating the separation between View and Control
b) I could do something like this in my action:
String type_url = "5";
request.setAttribute("url", type_url);
and then <c:when test="${item.type == url}">
but makes me wonder if having this code in the action really makes sense.
Any ideas?
Thanks
Luca
