JSTL toUpperCase 2007-01-24 - By bjorn.de.bakker@(protected)
Back
Seems straight-through, but apparently it isn't.
I have an object in the session scope, of which I need to show some attributes.
Some of them need to be converted to upper case. You can use functions for
that, but the problem is that I get a lot of errors :-/.
My taglib-definition looks as follows:
<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jstl/functions" prefix="fn" %>
If I put jstl/jsp/__ I get an error, stating that the URI cannot be resolved.
If I leave the jsp out of the URL, everything works fine for c and fmt, but the
tag library for functions can't be resolved. I've put the fn.tld in my web-app
folder, where I've also put the others.
If I do this:
%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:out value="${fn.toUpperCase(person.lastName)}" />
I get the following error:
<h3>Validation error messages from TagLibraryValidator for c in /dynamic/view
/ViewPersonView.jsp</h3><p>39: tag = 'out' / attribute = 'value': An error
occurred while parsing custom action attribute "value" with value "${fn
.toUpperCase(person.lastName)}": Encountered "(", expected one of ["}", ".", ">"
, "gt", "<", "lt", "==", "eq", "<=", "le", ">=", "ge", "!=", "ne", "[", "+", "-"
, "*", "/", "div", "%", "mod", "and", "&&", "or", "||"]</p>
If I change it to fn.UpperCase (as the tld mentions), I get the same error.
Can anybody tell me what I'm doing wrong, or how I can fix this? It's really
annoying, since google tells me I have to do it this way. Declaration of the
tag library is identical to core and fmt, and they work like a charm.
