I have an arraylist of objects. Each object has 3 properties. They
are:

DefectID - Integer
Description - VARCHAR
PriorityID - Integer

Those types are in the database - in Java they are int, String and int.

I hit my Oracle database and poplulate a list with the aforementioned
objects. I'm just trying to display the list in my .jsp page. Can
someone please tell me what is wrong the code in my .jsp page that is
shown below?

<%@page import="java.util.ArrayList"%>
<%@page import="EricEnhancementServiceImpl" %>
<%@ page import="java.util.*" %>
<%
List results = new ArrayList();

No need for creating this object as you assign to result
two lines below.

     EricEnhancementServiceImpl E = new EricEnhancementServiceImpl();
    results = E.getDefects1();

    pageContext.setAttribute("defects", results, pageContext.PAGE_SCOPE);

%>

<html>
<head>
<title>display</title>
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
</head>
<body>

<table border="1" width="80%">
    <tr><th>Description</th></tr>
    <c:forEach var="defect" items="${PageScope.defects}">

<c:forEach var="defect" items="${defects}">

should be OK.

Try:

<td><c:out value="${defect.description}"/></td>

ot with a recent JSP version:

<td>${defect.description}"</td>

</tr>
</c:forEach>
</table>
</body>
</html>
