[jdom-interest] Error in building SAX2 driver

Thu Jul 26 15:48:31 PDT 2001

Hello,
I got this error in the very first example that I executed using JDOM. When
I used DOM my JSP/XML example worked perfectly.
this is the code structure and below that is the error generated also.
I m running JBOSS with TOMCAT server.
I have the jdom and xerces jar files in my application lib directory.

WEB-INF
----lib
--------jdom.jar
--------xerces.jar

this is the example from chapter 12 - JSP and XML (page 421) from
Professional JSP 2nd edition (WROX)

<%@ page language="java" import="java.io.*, org.jdom.*,
org.jdom.input.SAXBuilder" %>
<%! File docfile = new
File("/usr/local/JBoss-2.2.1_Tomcat-3.2.1/tomcat/webapps/satyan_cobite/messa
ge.xml" ); %>

<html>
<head>
<title>First xml java test page</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body bgcolor="#FFFFFF" text="#000000">
<%

	SAXBuilder builder = new
SAXBuilder("org.apache.xerces.parsers.SAXParser" );
	Document l_doc = builder.build(docfile);

%>

This is a test page.....

the value in xml file is : <%=
l_doc.getRootElement().getChild("message").getText() %>

</body>
</html>
