JSTL 1.2 + Servlet 3.0 + Tomcat 7 = NIghtmare

Using MyEclipse 10.1

Have defined my project’s 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"
     version="3.0"> 

Have NO tld defined in web.xml

Have downloaded the glassfish API and IMPL for JSTL 1.2 (Servlet 3.0 compliant), with these Maven dependencies and also in the MyEclipse project to make Eclipse happy. But notice they are given a scope of <provided>. If I don’t do that, Tomcat 7 complains of LinkageExceptions.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>javax.servlet.jsp.jstl</artifactId>
    <version>1.2.1</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>javax.servlet.jsp.jstl-api</artifactId>
    <version>1.2.1</version>
    <scope>provided</scope>
</dependency>

Have the following statement at the top of the JSP:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

Note this is the allegedly correct path for JSTL 1.2

At this point, MyEclipse makes no complaints.
There are no other JSTL jars in the Tomcat 7 lib or in my WEB-INF/lib directory.

When I hit the page that has the JSPs, I get this exception:

org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

What am I doing wrong? Any ideas?
