<!--web.xml--> <web-app 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-app_3_0.xsd"     id="webapp_id" version="3.0" > <!-- register tld context , associating unique uri can further used refer tld. optional declaration, you![enter image description here][1] can refer tld directly, explain other options of referring tld in jsp page after example  -->     <taglib>         <taglib-uri>mytags</taglib-uri>         <taglib-location>/web-inf/mytags.tld</taglib-location>     </taglib> </web-app>  <!--mytags.tld--> <!doctype taglib   public "-//sun microsystems, inc.//dtd jsp tag library 1.2//en"          "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">  <taglib>     <tlib-version>1.1</tlib-version>     <jsp-version>1.2</jsp-version>     <short-name>exampletags</short-name>     <info>example custom tags</info>     <uri>http://www.mysite.com/jspexamples/exampletags</uri>      <tag>         <name>getmessage</name>         <tag-class>com.santosh.jspex.customtags.hellotaghandler</tag-class>         <body-content>empty</body-content>     </tag> </taglib>  <!--testpage.jsp--> <!-- declare taglib definations making translator aware of custom tags have defined --> <%@taglib uri="mytags" prefix="exampletags"%>  <html> <body> <b>response of getmessage tag : </b> <i> <exampletags:getmessage/> </i> <br> </body></html> <!--a tag handler class defined -->

your web.xml elements defined according pre 2.5 servlet spec. because using 2.5 or post 2.5(3.0) servlet spec, below: 

<jsp-config>   <taglib>         <taglib-uri>mytags</taglib-uri>         <taglib-location>/web-inf/mytags.tld</taglib-location>  </taglib> <jsp-config>
