Hi,

There is nothing related to Wicket in your question.
I think you should ask in the respective PayPal forums.
Once they suggest how to accomplish the task you can come back here to ask
how to do it in the Wicket way.

Hi Jayesh,
For IPN whether it is the the sandbox or live, you have to provide an URL
that is accessible from outside your local network.

IPN is a third party system, so if you tell IPN to send its requests to
localhost, it will send requests to IPN's localhost.

You need to open up a port on your network: 80, 443, 8080 or 8443, look up
your public IP address and provide it to IPN simulator.

Since I'm working from home, on my router, I opened up port 80 directed all
traffic to my development machine.
You can tell your router to redirect all traffic from port 80, to send it to
your machine on port 8080. 

Don't forget to open up the above ports on your development machine as well.

If you are at an office then you can ask your sys admin to open up the above
ports and redirect them to your machine, but you still have to open up the
ports on your development machine.

I hope this helps and not make things more confusing for you.
Any questions, just ask.

Regards,
Lucas

Hello lucas and vishal, 

Thanks for your replies they were of great help. The payment seems to be
working great, and I checked the IPN by creating a local  and adding
values like those paypal would send, however, is there a way to check it
with the paypal's ipn_simulator, as when ever I make a payment I cannot see
anything from the ipn class happening, is it because of the localhost ? and
if it is, is there a way to test the ipn on localhost ? I tried by providing
my ip address in the ipn_simulator but it gives an error stating that,
paypal was unable to connect to the url.

Thanks and Regards,
Jayesh

Re: Paypal Integration in wicket

2015-04-20 Thread vp143

Hi jayeshps,

I have implemented PayPal IPN in the following way:

In the html form you submit, you set the notifyUrl to a path i.e.
www.example.com/payment/ipn

In my Application class I have the following: mountPage("/payment/ipn",
IPNPaymentHandler.class);

Then my IPNPaymentHandler.class is as follows:

public class IPNPaymentHandler extends WebPage {
private static final Log log =
LogFactory.getLog(IPNPaymentHandler.class);
public IPNPaymentHandler() {
super();
log.debug("IPN Payment being received");
Request request = getRequest();

try {
Set paramSet =
request.getRequestParameters().getParameterNames();
Iterator iterator = paramSet.iterator();

StringBuffer sb = new StringBuffer();
sb.append("cmd=_notify-validate");
while(iterator.hasNext()){
String paramName = (String)iterator.next();
String paramValue =
request.getRequestParameters().getParameterValue(paramName).toString();
sb.append("&" + paramName + "=" + 
URLEncoder.encode(paramValue,
"UTF-8"));
}

URL u = new 
URL(AppUtil.getSettings().getPayPalWebsiteStandardUrl());
URLConnection uc = u.openConnection();
uc.setDoOutput(true);

uc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
PrintWriter pw = new PrintWriter(uc.getOutputStream());
pw.println(sb.toString());
pw.close();

BufferedReader in = new BufferedReader(new
InputStreamReader(uc.getInputStream()));
String res = in.readLine();
in.close();

// assign posted variables to local variables
String itemName =
request.getRequestParameters().getParameterValue("item_name").toString();
String itemNumber =
request.getRequestParameters().getParameterValue("item_number").toString();
String paymentStatus =
request.getRequestParameters().getParameterValue("payment_status").toString();
String paymentAmount =
request.getRequestParameters().getParameterValue("mc_gross").toString();
String paymentCurrency =
request.getRequestParameters().getParameterValue("mc_currency").toString();
String txnId =
request.getRequestParameters().getParameterValue("txn_id").toString();
String receiverEmail =
request.getRequestParameters().getParameterValue("receiver_email").toString();
String payerEmail =
request.getRequestParameters().getParameterValue("payer_email").toString();

//check notification validation
if(res != null && res.equals("VERIFIED")) {
if(paymentStatus.equals("Completed")) {
//Do business logic
}
else {
log.debug("paymentStatus = " + 
paymentStatus);
}
}
else if(res != null && res.equals("INVALID")) {
log.info("result = " + res);
log.info("itemName = " + itemName + " 
itemNumber = " + itemNumber + "
paymentStatus = " + paymentStatus + " paymentAmount = " + paymentAmount + "
" + paymentCurrency);
log.info(" txnId = " + txnId + " receiverEmail 
= " + receiverEmail + "
payerEmail = " + payerEmail);
}
else {
log.info("result = " + res);
log.info("itemName = " + itemName + " 
itemNumber = " + itemNumber + "
paymentStatus = " + paymentStatus + " paymentAmount = " + paymentAmount + "
" + paymentCurrency);
log.info(" txnId = " + txnId + " receiverEmail 
= " + receiverEmail + "
payerEmail = " + payerEmail);
}
}
catch(MalformedURLException mue) {
mue.printStackTrace();
}
catch(IOException ioe) {
ioe.printStackTrace();
}
}

}

The above is just the skeleton where you can fine tune to your needs... 
Please do let me know if you see any flaws payment needs to be done
right especially with security etc.

Regards
Vishal

Re: Paypal Integration in wicket

2015-04-20 Thread lucast

Hi Jayeshps,
I have implemented a wicket pay with paypal button a few weeks ago.

The beauty of working with wicket is that you do not have to hard-code and
hide the html parameters you pass to paypal on your html.
It can all be done on the AjaxButton.onSubmit();

I am assuming you're familiar with the parameter's passed to paypal, if not,
here is a good example:
http://www.onlineinteract.com/wiki/viewpage.php?pageId=179

Also, an explanation of each parameter can be found here

Ok, onto the code:

Inside the AjaxButton.onSubmit() button, you need to construct the URL with
parameters to pass to paypal:
An example url is this:
https://www.paypal.com/cgi-bin/webscr?cmd=_cart&upload=1&no_shipping=1&no_note=1&custom=0A566EC9F6AC27E9¤cy_code=GBP&lc=GB&bn=business_BuyNow_WPS_GB&return=https://localhost:8443/paymentpage/sucessParameters&cancel_return=https://localhost:8443/paymentpage/cancelParameters¬ify_url=https://localhost:8443/paypalipnprocess&business=ad...@businessowner.com&item_name_1=entry_test_test&item_number_1=DB3BE2BD0BFC8D03&amount_1=0.30

Notice how all parameters are separated by '&'.

You can produce the above URL from the server side, avoiding posting all of
the above info in hidden fields on the HTML form post parameters.

The way I have implemented is as follow:
AjaxButton.onSubmit()
{
setResponsePage(new PayPalPaymentGatewayExampleClass(parameters to
construct the url));
}

I've attached the PayPalPaymentGatewayExampleClass which extends
RedirectPage2 on this post.
PayPalPaymentGatewayExampleClass.java

RedirectPage2.html

RedirectPage2.java

PayPalPaymentGatewayExampleClass builds the URL with the necessary
parameters before posting the request to Paypal.

Notice that on RedirectPage2 I throw new RedirectToUrlException(
url.toString() );
That's because I was having trouble to properly rediderct a page running
wicket on production mode. I spent days trying to find a solution. Finally,
I had to settle for the workaround but functional RedirectToUrlException.

Part 2, processing the IPN:

Once the payment has taken place, Paypal will send the IPN request to you.
If you haven't played with Paypal's IPN simulator, you can do so here
. Remember to provide
a valid url to IPN handler URL since IPN is a 3rd party trying to contact
your application. localhost will not do.

2015-04-17 Thread jayeshps

Hello, 

IPN is short for Instant Paypal Notification, it is a notification service,
which runs while a user is trying to make a payment after clicking on the
facebook button on my web application. unless a confirmation is sent from my
application to paypal the payment will not be confirmed, this is done to
hinder any man in the middle attack.


I also tried using the implementation like shown in
https://github.com/paypal/PayPal-Java-SDK, but it does not seem to redirect
to the paypal's website.
