According to TLD or attribute directive in tag file appears in the JSP, attribute value does not accept any expressions

JSP exception occurs when application deployment runs, when using the JSTL library: according to TLD or attributes Directive in tag file, attribute value does not accept any expressions, perhaps because of the use of the JSP2.0 version, while not using an alternate version of the JSTL Core library (RT library), there are two ways to handle this:

1. Modify Web.xml. <web-app xmlns= "Http://java.sun.com/xml/ns/j2ee" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "Http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version= "2.4" >

To version 2.3 <! DOCTYPE Web-app Public "-//sun Microsystems, INC.//DTD Web Application 2.3//en" "Http://java.sun.com/dtd/web-app_2_3. DTD ">
<web-app>

2. Use Jstl Core RT Library

The JSTL Core Library has two taglib pseudo directives, in which the RT library relies on the JSP's traditional request-time attribute value, rather than relying on El to implement it (called the El Library. JSP2.0 will support EL)

JSP in the use of <%@ taglib uri=http://java.sun.com/jstl/core prefix= "C"%> in the 2.3 version can be, in 2.4 is not, is the version incompatible?

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

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

There's no problem.
