Error using JSTL tag: According to TLD or attributes Directive in tag file, attribute value does not accept any expressions

Using JSTL tag does not require the following code to be added to the web.xml:

<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/tld/fmt.tld</taglib-location>
</taglib>
</jsp-config>

And just put Jstl.jar and Stardard.jar into the Web-inf/lib directory to use

For JSTL core tag, if you use the following declaration:

<%@ taglib prefix= "C" uri= "Http://java.sun.com/jstl/core"%>

The return is wrong:

According to TLD or attributes Directive in tag file, attribute value does not accept any expressions

The solution is to change the declaration to

<%@ taglib prefix= "C" uri= "Http://java.sun.com/jstl/core_rt"%>
