Use Weblogic to Run Custom JSP Tag -- Please Help!!!

I am using the Weblogic 5.1.0 to try out the Tag Handler Class (Lisgings 14.10, 14.11, 14.12) in Marty Hall's book entitled "Core Servlets and JavaServer Pages".
After I typed: http://localhost:7001/HeadingExample.jsp
in IE browser window
I got error message:
Parsing of JSP file '/HeadingExample.jsp' failed: Could not parse deployment descriptor: org.xml.sax.SAXParseException:Could not parse taglib, starting at line 6.
probably occurred due to an error in /HeadExample.jsp line 16:
<%@ taglib uri="\Web-inf\csajsp-taglib.tld" prefix="csajsp" %>
I compiled HeadingTag.java and saved the compiled file in:
c:\weblogic\myserver\servletclasses\coreservlets\tags\HeadingTag.class
The library file csajsp-taglib.tld is in:
c:\weblogic\myserver\public_html\Web-inf\csajsp-taglib.tld
and the jsp file HeadingExample.jsp is in
c:\weblogic\myserver\public_html\HeadingExample.jsp
All three files are directly downloaded from the web www.coreservlets.com. Could anybody tell me what I did wrong and how to make this example work? Thanks a lot in advance.

This means there is some problem in your .tld file. If your .tld file is correct, you can see a java file being created.
Check your .tld file format from sun's format.
Here is the sample ".tld" file
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<!-- a tag library descriptor -->
<taglib>
<!-- after this the default space is
"http://java.sun.com/j2ee/dtds/jsptaglibrary_1_2.dtd"
-->
<tlibversion>1.0</tlibversion>
<jspversion>1.1</jspversion>
<shortname>mytag</shortname>
<uri></uri>
<info>
A simple tab library for the examples
</info>
<tag>
<name>example</name>
<tagclass>com.test.ExampleTag</tagclass>
<info> Display JSP sources </info>
</tag>
</taglib>

Hope this helps!
