I am working with Netbeans 8.2 and Java 8 version, when executing my program from the Netbeans IDE it runs without problem but from the command line it gives me the following error:

java -jar MiPrograma.jar

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/netbeans/lib/awtextra/AbsoluteLayout

In some forums they recommend adding the AbsoluyteLayout library to the classpath, which I select from the following path:

..\NetBeans 8.2\java\modules\ext\AbsoluteLayout.jar

I have done it this way but it keeps giving me the same error, can someone help me with this problem. Thanks.

My problem is the following, I have a page that contains a button, clicking on it builds a table that reads data from a database. What you need to do is add the paging and searching, but it doesn't, it just builds the table.

I make the clarification that I made this example in this way because I need to build the table based on different filters.

This is my index.php

<!DOCTYPE html>
<html>
    <title>Datatable</title>
    <head>

        <!-- Bootstrap and Jquery-->        
        <link rel="stylesheet" href="css/bootstrap.min.css" type="text/css" />
        <script src="js/bootstrap.min.js"></script>
        <script src="js/jquery-3.3.1.min.js"></script>

        <!-- Icons -->
        <link rel="stylesheet" href="font/css/open-iconic-bootstrap.min.css">

        <!-- Datatables-->
        <script type="text/javascript" language="javascript" src="js/jquery.dataTables.js"></script>
        <link rel="stylesheet" href="css/jquery.dataTables.css" type="text/css" />

        <script type="text/javascript" language="javascript" src="js/script.js"></script>

    </head>

    <body>
        <div class="container">
            <h3 align="center">DataTable Example</h3>       
            <button type="button" onclick="show_table()"> Create </button>      
            <div id="mydiv">

            </div>      
        </div>
    </body>
</html>

The following function is executed in javascript when the button is clicked (script.js)

function show_table() {

    var url = 'table.php';
    var method = 'POST';

    ajax (url, method, 'mydiv');
}


function ajax (url, method, container_id) {
    try {
        xhr = new XMLHttpRequest();
    } catch(e) {
        try{
            xhr = new ActiveXObject("Microsoft.XMLHTTP");
        } catch(e1) {
            alert("Not supported!");
        }
    }

    xhr.onreadystatechange = function() {
                               if(xhr.readyState == 4) {
                                   document.getElementById(container_id).innerHTML = xhr.responseText;
                               } 
                            }
    xhr.open(method, url, true);
    xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
    xhr.send();
}

Here is the PHP that builds the table (table.php)

<?php

$connect = mysqli_connect("localhost", "root", "", "test");
$query = "select * from employee order by id desc";
$result = mysqli_query($connect, $query);

?>

<table id="employee-data" class="table table-striped">
                    <thead>
                        <tr>
                            <td>Employee name</td>
                            <td>Salary</td>
                            <td>Age</td>
                            <td>View</td>
                            <td>Edit</td>
                            <td>Delete</td>
                        </tr>
                    </thead>

<?php

while ($row = mysqli_fetch_array($result))
{
echo '
<tr>
    <td>'.$row["employee_name"].'</td>
    <td>'.$row["employee_salary"].'</td>
    <td>'.$row["employee_age"].'</td>
    <td><button type="button" class="btn btn-outline-primary"><span class="oi oi-account-login"></span></button></td>
    <td><button type="button" class="btn btn-outline-primary"><span class="oi oi-pencil"></span></button></td>
    <td><button type="button" class="btn btn-outline-primary"><span class="oi oi-trash"></span></button></td>
</tr>

';
}

?>

</table>

<script>
$(document).ready(function() {
    $('#employee-data').DataTable();
} );
</script>

I hope you can help me with this problem, I appreciate any input.
