Netbeans Error : Schema doesnt exist

So i am trying to access my underlying database in java application in netbeans through a simple jsp page :

<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<sql:query var="rslt" dataSource="jdbc/cart">
   select isbn, title, quantity, price from dbsample.books
</sql:query>
<html>
<head>
     <title>JDBC Connection Test</title>
 </head>
 <body>
    <h1>Available books:</h1>
    <c:forEach var="book" items="${rslt.rows}">
        <b>Isbn:</b> ${book.isbn}<br/>
        <b>Title:</b> ${book.title}<br/>
        <b>Price:</b> $${book.price}<br/>
        <b>In stock:</b> ${book.quantity}<br/>
        <br/>
    </c:forEach>
 </body>
</html>

but i am getting this error :

select isbn, title, quantity, price from dbsample.books : Schema 'DBSAMPLE' does not exist

This is the stack trace:

Now i have checked my web.xml. the deployment descriptor is correct to the best of my knowledge. I have checked my datasource it seems correct to according to my persistance.xml I pinged the database pool and it was successful too. My schema is named dbsample and has a table named books.

So i cant figure out why it is saying to my DBSAMPLE doesnt exist. Any help would be highly appreciated.

EDIT # 1 when executing the sql command in database it works totally fine. enter image description here

Although I might be a little late to answer this, but I came across the same problem and solved it.

The problem was that I did not set the JDBC resource in my persistnece.xml. I added this to my persistence.xml:

<jta-data-source>jdbc/resourcename</jta-data-source>

Change jdbc/resourcename to your JDBC resource!
