No ,
If you are using JSTL , yes you need to add a few classes to your source path.
But for custom tags, you dont need to install anything extra other than the jdk and the web container/J2ee container.
So if a normal servlet program , JSP program runs, then there is some other problem with your code.

No, only things you need are JSP page, tld file and Tag handler
Try this

customTag.jsp

<%@ taglib prefix="myTags" uri="simpleTag"%>
<html><body>
<myTags:simple1/>
</body></html>

SimpleTag.tld

<?xml version="1.0" encoding="ISO-8859-1" ?>

<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">

<tlib-version>0.9</tlib-version>

<short-name>simpleTags</short-name>
<uri>simpleTag</uri>
<tag>
<description>Use of custom tags</description>
<name>simple1</name>
<tag-class>com.example.web.SimpleTagTest1</tag-class>
<body-content>empty</body-content>
</tag>
</taglib>

com/example/web/SimpleTagTest1.java
package com.example.web;
import javax.servlet.jsp.tagext.SimpleTagSupport;
import java.io.IOException;
import javax.servlet.jsp.JspException;
public class SimpleTagTest1 extends SimpleTagSupport{
public void doTag() throws JspException,IOException{
getJspContext().getOut().print("This is the use of custom tag");
}
}

yeah, but ... what would PIE do? Especially concerning this tiny ad:
