Question on defining taglib in web.xml

Question

I am using netbeans to develop a j2ee5 web application.
I created a web application project using the wizard.
When I defined a <taglib> in the web.xml, it detected an error.
cvc-complex-type.2.4.a: Invalid content was found starting with element 'taglib'. One of '{"http://java.sun.com/xml/ns/javaee":description, "http://java.sun.com/xml/ns/javaee":display-name, "http://java.sun.com/xml/ns/javaee":icon, "http://java.sun.com/xml/ns/javaee":distributable, "http://java.sun.com/xml/ns/javaee":context-param, "http://java.sun.com/xml/ns/javaee":filter, "http://java.sun.com/xml/ns/javaee":filter-mapping, "http://java.sun.com/xml/ns/javaee":listener, "http://java.sun.com/xml/ns/javaee":servlet, "http://java.sun.com/xml/ns/javaee":servlet-mapping, "http://java.sun.com/xml/ns/javaee":session-config, "http://java.sun.com/xml/ns/javaee":mime-mapping, "http://java.sun.com/xml/ns/javaee":welcome-file-list, "http://java.sun.com/xml/ns/javaee":error-page, "http://java.sun.com/xml/ns/javaee":jsp-config, "http://java.sun.com/xml/ns/javaee":security-constraint, "http://java.sun.com/xml/ns/javaee":login-config, "http://java.sun.com/xml/ns/javaee":security-role, "http://java.sun.com/xml/ns/javaee":env-entry, "http://java.sun.com/xml/ns/javaee":ejb-ref, "http://java.sun.com/xml/ns/javaee":ejb-local-ref, "http://java.sun.com/xml/ns/javaee":service-ref, "http://java.sun.com/xml/ns/javaee":resource-ref, "http://java.sun.com/xml/ns/javaee":resource-env-ref, "http://java.sun.com/xml/ns/javaee":message-destination-ref, "http://java.sun.com/xml/ns/javaee":persistence-context-ref, "http://java.sun.com/xml/ns/javaee":persistence-unit-ref, "http://java.sun.com/xml/ns/javaee":post-construct, "http://java.sun.com/xml/ns/javaee":pre-destroy, "http://java.sun.com/xml/ns/javaee":message-destination, "http://java.sun.com/xml/ns/javaee":locale-encoding-mapping-list}' is expected.
Here is my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">
<welcome-file-list>
<welcome-file>
index.jsp
</welcome-file>
</welcome-file-list>
<taglib>
<taglib-uri>/mytag</taglib-uri>
<taglib-location>/WEB-INF/mytag.tld</taglib-location>
</taglib>
</web-app>

Answer 1

As of servlet 2.4 (jsp 2.0), you'll have to move the taglib declarations inside a <jsp_config> element.
<jsp-config>
    <taglib> ..........your stuff
</jsp-config>ram.
