好像还是不行。

Work around from:
http://forge.objectweb.org/forum/forum.php?thread_id=1212&forum_id=360
when you import your taglibs, use the -rt versions and everything will be fine.

example:

use
<%@ taglib uri="WEB-INF/tld/c-rt.tld" prefix="c" %>

instead of just

<%@ taglib uri="WEB-INF/tld/c.tld" prefix="c" %>

Twin Libraries
The JSTL tag libraries come in two versions which differ only in the way they support the use of runtime expressions for attribute values.

In the JSTL-RT tag library, expressions are specified in the page's scripting language. This is exactly how things currently work in current tag libraries.

In the JSTL-EL tag library, expressions are specified in the JSTL expression language. An expression is a String literal in the syntax of the EL.

When using the EL tag library you cannot pass a scripting language expression for the value of an attribute. This rule makes it possible to validate the syntax of an expression at translation time.
