How do you use JSTL?
Trying to use JSTL but 开发者_StackOverflowhave the following problem:
Index.xhtml page:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:fmt="http://java.sun.com/jsp/jstl/fmt"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:ice="http://www.icesoft.com/icefaces/component" xmlns:jsp="http://java.sun.com/JSP/Page">
<body>
<c:out value="Hello world!"/>
</body></html>
POM:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
OUTPUT SOURCE:
<html id="document:html" lang="en" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:fmt="http://java.sun.com/jsp/jstl/fmt" xmlns:jsp="http://java.sun.com/JSP/Page"><head><meta content="Rendered by ICEFaces D2D" name="icefaces" />
.....
<c:out value="Hello world!"></c:out>
....</body></html>
As you can see its not processing the c:out but just printing it out as text.
Seems that:
The solution is to remove the /jsp from the jstl namespace:
xmlns:c="http://java.sun.com/jstl/core"
See this post.
I could solve the problem with adding
xmlns:fmt="http://java.sun.com/jsp/jstl/fmt" in my xhtml file.
OR
declaring this in my web.xml, and copying the c.tld in /WEB-INF/jsp from my application:
<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/jsp/c.tld</taglib-location>
</taglib>
</jsp-config>
Warning: xmlns:c="http://java.sun.com/jstl/core" throws exception, collected in my h:messages Tag
加载中,请稍侯......
