Tag file directory /WEB-INF/functions.tld does not start with "/WEB-INF/tags"

I have an interesting issue... I am trying to add a JSP Tag to my application. I have stored a functions.tld in /WEB-INF/tags/ but I get the error message Illegal TLD path /WEB-INF/tags/functions.tld, must not start with "/WEB-INF/tags" so I tried to move it /WEB-INF/ which I then get Tag file directory /WEB-INF/functions.tld does not start with "/WEB-INF/tags". So where am I supposed to put it!!

TLD File

<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
        version="2.1">

    <tlib-version>1.0</tlib-version>
    <short-name>my</short-name>

    <!-- Invoke 'Generate' action to add tags or functions -->
    <function>
        <name>urlencode</name>
        <function-class>library.StringUtils</function-class>
        <function-signature>java.lang.String urlencode(java.lang.String)</function-signature>
    </function>

</taglib>

JSP File

<%@ taglib prefix="f" tagdir="/WEB-INF/tags/functions.tld" %>

Error when not in tag folder

It is a simple misunderstanding. Reasoning about it a little, it does not make much sense to use an attribute tagdir to refer to a single tag file. The correct way to achieve it is to indeed put the TLD file in the WEB-INF directory and then refer to it using

<%@ taglib prefix="f" uri="/WEB-INF/functions.tld" %>

In other words: replace tagdir with uri.

This existing question and answer explains the difference.
