TLD and Deployment Descriptor not Working

This is a simple hello world custom tag.
Im storing my TLD and DD in the WEB-INF directory, and by the way Im using Tomcat 4.
When I start the server it doesnt properly startup , it gives me a bunch of errors.

This my source for TLD:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>Hello World</short-name>
<description>A Simple Hello World</description>
<tag>
<name>helloworld</name>
<tag-class>custom.ch09.HelloWorld</tag-class>
<body-content>empty</body-content>
</tag>
</taglib>
This is the code for web.xml
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<display-name>Chapter 9 examples</display-name>
<description>Really simple Hello World</description>
<taglib>
<taglib-uri>/helloworldtags.tld</taglib-uri>
<taglib-location>/WEB-INF/helloworldtags.tld</taglib-location>
</taglib>
</web-app>

When I try to access it using http://localhost/test/hello.jsp
This is the error it gives me:
