How to configure tld file?

Question

I am building a JSF application and created a new custom component with a new tag. I suspect the runtime isn't finding/loading my TLD file. I've tried putting the TLD file in the WEB-INF directory and with the source/class files; I get the same error. How can I figure out if my tld is loaded? what else can I try to get it to be recognzied properly?
The error is:
Attribute id invalid for tag TestTag according to TLDMy TLD file does specify id:
          <attribute>
               <name>id</name>
               <required>false</required>
               <rtexprvalue>false</rtexprvalue>
               <description>
                    The component identifier for this component. This value
                    must be unique within the closest parent component that
                    is a naming container.
               </description>
          </attribute>

Answer 1

If I flat out delete the tld file, and restart my IDE and the web server, I get the exact same symptoms. My custom tag/component works perfectly with a value attribute but no id attribute. As soon as I add the id attribute, I get the error.
I can also put the tld file back, but delete the XML contents and type in garbage; this way, if something was trying to read that file it would error. I get no error, which tells me that nothing is reading that file. If I remove the id attribute, it works perfectly.
My import statement:
<%@ taglib uri="http://sample.com/taglibs/" prefix="xyz"%>My tag reference:
<td><xyz:rater value="#{sample.value}" /></td>Java: 1.5.0_06
Server: Apache Tomcat 5.5.12
JSF: Sun RI 1.1_01
IDE: Eclipse 3.1.1 + WTP 1.0RC5
Yes, in my web searches, I saw many places recommending adding a taglib section to web.xml, but it wouldn't validate and seemed to be obsolete.
