[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - JSTL on JBoss 4.0.2

Thu Oct 26 14:02:43 EDT 2006

Hi,
I'm trying to deploy the simple hello1 web project from the J2EE 1.4 tutorial on JBoss 4.0.2. Although it deploys fine and I can access the page, the behavior is not correct. When I enter some text and hit submit, then the text "Hello <some text>" should also be displayed on the page. However, this does not happen, which leaves me to believe that the JSTL tags are not being evaluated. 

This is the index.jsp:

  | <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
  | <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
  | <html>
  | <head><title>Hello</title></head>
  | <body bgcolor="white">
  | <img src="duke.waving.gif"> 
  | <h2>Hello, my name is Duke. What's yours?</h2>
  | <form method="get">
  | <input type="text" name="username" size="25">
  | <p></p>
  | <input type="submit" value="Submit">
  | <input type="reset" value="Reset">
  | </form>
  | 
  | <c:if test="${fn:length(param.username) > 0}" >
  |   <h2><font color="black">Hello, ${param.username}!</font></h2>
  | </c:if>
  | </body>
  | </html>
  | 

This is the web.xml in use:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <!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>
  |   <display-name>hello1</display-name>
  |   <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/functions</taglib-uri>
  |   	<taglib-location>/WEB-INF/tld/fn.tld</taglib-location>
  |   </taglib>
  | </web-app>
  | 

I've packaged everything in a war with the web.xml file under WEB-INF, the tld files under WEB-INF/tld and the jstl.jar and standard.jar under WEB-INF/lib.

Any ideas on what's going on?
Thanks,
Tai
