according to tld or attribute directive in tag file attribute *** does not accept any expressions

Your JSTL taglib URI is wrong. The one which you've there is for legacy JSTL 1.0. Since JSTL 1.1 there's an additional

/jsp

path in the taglib URI, because expression language (those

${}

things) has been moved from JSTL to JSP and hence taglibs of JSTL 1.0 and 1.1 are not interchangeable.

如果原因是如上，则把下面的

<%@ taglib uri='http://java.sun.com/jstl/core' prefix='c'%>

修改为

<%@ taglib uri='http://java.sun.com/jsp/jstl/core' prefix='c'%>
