    copied!<p>Greetings,</p> <p>I'm attempting to write my first Java Bean + JSP page from scratch. However, I'm using a 2D array which is populated with arbitrary values, and I'm now getting an exception when I run the JSP saying that the array property cannot be found:</p> <pre><code>JSP Exception: javax.el.PropertyNotFoundException: Property 'utilTableVals' not found on type diskUtil.tester </code></pre> <p>Here is my bean code:</p> <pre><code>package diskUtil; import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.*; import java.lang.*; import java.io.*; public class tester{ //public String [][] utilTableVals; String [][] utilTableVals = new String[20][20]; /*** bean's properties accessor ***/ /*public String[][] getUtilTableVals() { return utilTableVals; }*/ public static String[][] getUtilTableVals()throws Exception{ tester du1 = new tester(); //String [][] utilTableVals = new String[20][20]; int i=0; int j=0; int row=0; int col=0; int result=0; for(int r = 0; r &lt; du1.utilTableVals.length; r++) { for(int c = 0 ; c &lt; du1.utilTableVals[r].length; c++) { result = r+c; du1.utilTableVals[r][c]=Integer.toString(result); //System.out.print(" " + utilTableVals[r][c]); } } return du1.utilTableVals; }//end getUtilTableVals </code></pre> <p>My JSP Code is here:</p> <pre><code>&lt;%@ page contentType="text/html" %&gt; &lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; &lt;hmtl&gt; &lt;head&gt; &lt;title&gt;Disk Utilization Page&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;DISK UTILZATION REPORT&lt;/h1&gt; &lt;br&gt; &lt;jsp:useBean id="diskUtilData" scope="request" class="diskUtil.tester" /&gt; &lt;table&gt; &lt;c:forEach var="celldata" items="${diskUtilData.utilTableVals}"&gt; &lt;tr&gt; &lt;c:forEach var="col" items="${celldata}"&gt; &lt;td&gt; &lt;c:out value="${col}" /&gt; ${col} &lt;p&gt;hello&lt;/p&gt; &lt;/td&gt; &lt;/c:forEach&gt; &lt;/c:forEach&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Could someone please have a look? Thanks in advance.</p> <p>-TU</p>
