Your question is not clear. Try to explain in more detail.

Developing a Robust and Secure Online Payment System in Java EE

30-May-13 23:25

Without knowing the structure of your database or your application it's impossible to say more than: Read the first set of items and populate the first listbox. Then when an item is selected in the listbox use its content to read the next list in sequence and populate the next listbox. And do on as each listbox selection changes.

I am an intermediate Java EE developer who wants to develop an online payment system that would work with either a bank or other online payment systems. My problem is because I am inexperienced in this area, the solution I have may not be robust and secure enough, I would like to know what are the issues I have to consider and if possible code samples with explanation to solving this problem.

In which case it would not be a good solution. A much better idea whould be to use the interface from a commercial and professional payment gateway such as PayPal.

Fine, go ahead. But if you are having problems then you need to explain in better detail.

Hello,

A very simple to do this on client side as opposed to server side, is to output all the required data in form of javascript. Since you are talking about javascript the obvious choice is to output it as a JSON. PLease find below a sample JSON and the code to use it to populate the listboxes.

HTML

<html>
<head>
<title>List Demo</title>
<script type="text/javascript">
var lstData = {
    "key1" : {,
         "value":"value1",
         "sublist": [
             {
                 "key": "key1_1",
                 "value":"value1_1",
             },
             ...
         ]
    },
    ...
};

function fillList1() {
    var ctrl = document.getElementById('list1');
    ctrl.options.length = 0;
    for (var key : lstData) {
        var data = lstData[key];
        var opt = document.createElement('option');
        opt.value = key;
        opt.text = data.value;
        ctrl.options.add(opt);
    }
}

function fillList2(lstOne) {
    if (lstOne.selectedIndex < 1) return;
    var data = lstData[ctrl.value];    // Retrieve the data for selected item in list1
    var ctrl = document.getElementById('list2');
    ctrl.options.length = 0;    // Clear the combox
    for (var key : data.sublist) {
        var subitem = data.sublist[key];
        var opt = document.createElement('option');
        opt.value = subitem.key;
        opt.text = subitem.value;
        ctrl.options.add(opt);
    }
}
</script>
</head>
<body onload="fillList1();">
    <form name="frmMain" id="frmMain" method="post">
        <label for="list1">List 1 : </labl>
        <select name="list1" id="list1" size="1" onchange="fillList1(this);">
            <option value="">Select</option><br/>
        </select>
        <label for="list2">List 2 : </labl>
        <select name="list2" id="list2" size="1">
            <option value="">Select</option><br/>
        </select>
    </form>
</body>
</html>

You need to use Google to find references for this subject. There are many problems to be resolved in creating automatic schedules such as this, and the question is too broad for a technical forum.

I want to create a server socket(TCP) in which I want that server shouldn't be closed if
client is closed.
What I'm doing: I'm able to connect to client but when client is closed then server is throwing exception : Connection Reset and crashes
How can I do it?
