I have a JSP page that is suppose to display data using the servlet and session beans.
However when I run the project from the Netbeans project node. I get the error.

org.apache.jasper.JasperException: /index.jsp(9,0) PWC5988: Page directive: illegal to have multiple occurrences of 'contentType' with different values (old: text/html;

below is the JSP page.

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

<%@page contentType="text/html" pageEncoding="UTF-8"%>
 
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link rel="stylesheet" type="text/css" href="css/affablebean.css">
    <title>The Affable Bean</title>
    </head>
    <body>
    
        <div id="indexLeftColumn">
                <div id="welcomeText">
                    <p style="font-size: larger">Welcome to the online home of the Affable Bean Green Grocer.</p>

                </div>
            </div>

<div id="indexRightColumn">
                <c:forEach var="category" items="${categories}">
                    <div class="categoryBox">
                        <a href="category?${category.id}">
                            <span class="categoryLabel"></span>
                            <span class="categoryLabelText">${category.name}</span>

below is also the error from the IDE

I dropped your page into a Tomcat 6 environment and it ran without issue. I think netbeans is full of crap.

Try running it in a real environment, outside of netbeans.

That said, I always think that superfluous markup should be avoided. I'd just drop the page directive; it isn't doing anything meaningful and just adds extra markup to the JSP.
