[opencms-dev] NewsHack.zip Help!!!!

Tue Oct 21 05:52:02 CEST 2003

Hi,

I have created a file called "my_news.jsp" which is a slightly modified
version of "default_news.jsp" as contained in NewsHack.zip (downloaded from
http://opencms.al-arenal.de/). I am using OpenCms 5.0 with the news 2.0
module on Tomcat4.1.12.

my_news.jsp:
<%@ page session="false" import="java.util.*" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
<!doctype html public "-//W3C//DTD HTML 4.01 Translational//EN">
<html>
<head>
<meta HTTP-EQUIV="CONTENT-TYPE" CONTENT="text/html; CHARSET=<cms:property
name="content-encoding" default="ISO-8859-1" />">
</head>
<body>
<!-- Begin Page Content -->
<div id="content">
<cms:include element="body" />
<!-- Test News -->
<h1>News</h1>
<cms:include
file="/system/modules/com.opencms.modules.homepage.news/pages/news.jsp" />
</div>
</body>
</html>

I have followed the instructions in the readme.rtf contained in
NewsHack.zip.

1. how do you use NewsHack's "news.jsp" to view the news articles?
2. What is it that needs to be changed in NewsHack.zip's news.jsp,
news-nav.jsp and NewsItem.jsp? I've modified news.jsp's last line to be:
out.print("<p><a
href=\"/system/modules/com.opencms.modules.homepage.news/pages/NewsItem.jsp?
id="+newsItem.getID()+"\">"+newsItem.getHeadline()+"</a></p>");
Is there anything else that needs to be modified in these 3 files?

I get the following error when I try to run my_news.jsp:
javax.servlet.ServletException: Resource loader error in file
'/myProject/my_news.jsp'
