Using JSP standard tag library

liuchang Jan 24, 2005 2:58 AM

Hi, I'm a beginner trying to pick up J2EE, I ran into a problem for this very simple JSP page:

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<html>
<head><title>Tags</title></head>
<body>

</body>
</html>

When I request it through the web server, I get:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
 org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:50)
 org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:411)
 org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:118)
 org.apache.jasper.compiler.TagLibraryInfoImpl.generateTLDLocation(TagLibraryInfoImpl.java:316)
 org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:147)

The Sun J2EE tutorial says that the Sun J2EE reference implementation server has appserv-jstl.jar in its class path and therefore we only need to declare the tag library. Seems like it's not the case here. I looked under the jboss directory and found no file name containing jstl. Am I missing something here?

Oh, I'm using JBoss 4.0.1 without any configuration.

OK, I found out why. It turns out that JSTL is not part of JBoss/Tomcat (gasp). Refer to here: http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3856268#3856268

As was posted there, I copied standard.jar and jstl.jar from Sun's J2EE tutorial to my /WEB-INF/lib/ directory and reployed. Now it works. I'm not sure where else to get them or whether there're more "official" versions than in the tutorial.

So the "Standard Tag Library" is not part of the standard. Interesting.

Get jstl.jar and standard.jar from tomcat5/lib (http://jakarta.apache.org/site/binindex.cgi) into the /WEB-INF/lib/ directory of my war file. All is OK.
