paypal and spring mvc

[logixplayer]

hey Folks,

I got an issue and it driving me nuts. I am posting from a form to my Spring MVC 3 controller. Internally I am posting to paypal.
GOAL: To display the page that shows the item and the price charged to the customer.

What I keep getting is: "Please login to use the PayPal Sandbox features." WHEN I use the test url:
https://www.sandbox.paypal.com/cgi-bin/webscr

AND I get: "You have requested an outdated version of PayPal. This error often results from the use of bookmarks." when I use the official URL: https://www.paypal.com/cgi-bin/webscr

						String url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
		//url = "https://www.paypal.com/cgi-bin/webscr";
		//url = "https://developer.paypal.com";
		//url = "https://www.paypal.com/cgi-bin/webscr";
		//HttpParams httpParams = new BasicHttpParams();

		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

SO I am arriving at the paypal site its JUST that it keeps asking me to login OR giving me that "outdated version bookmark error". I did login through my browser so apparently a cookie is set in the browser, but this is posting through Java....

I suspect it has something to do with the headers because if I remove some of the values I get an exception...anyone know whats going on???

		httpPost.setHeader("User-Agent", "Mozilla/5.0 (Windows; U;Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7");

		  //conn.setRequestProperty( "User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.2; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0");
		//httpPost.setHeader( "Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
		 httpPost.setHeader("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");

		httpPost.setHeader( "Accept-Language", "en-us,en;q=0.5");

Ultimately I just want the paypal page to show with the item and the price so the customer can buy....any help would be greatly appreciated.

When I try to connect to the official paypal url, change my "BusinessName" which is basically the email I use to login officially (not my test account) and change the cmd to "_xclick",

I get a blank response:

String //url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
		url = "https://www.paypal.com/cgi-bin/webscr";

I tried all of this with a GET but I get a PayPal homepage.
I am stuck!!!!
I would just like to see the paypal page containing my item and the price.

Is there not a way to bypass "logging in" and clicking on a button??
Please advise. Thank you.

[logixplayer]

can anyone help me on this please?
My issue is that I have dynamic input which means that the amount is determined after it is posted. It is not a fixed amount.
I was on a similar site and I saw that they did the same thing I would like to do, it was some cgi program, probably using c or some other scripting language...

I know it is possible ...it just that I guess I am not setting up my GET command or my POST command properly...BUT I am including only those variables that are required for the <form> under regular conditions...I am just trying to simulate the form post...(or get)

Again, anyone out therE?? This one is just killing me...its been over a week....
please advise
thank you so much

Hi ppl,

I have a serious dilemma here. I am using Website Payment standard and I would like to integrate this with my java application. Basically the user submits a form, it is intercepted by my controller and some validation happens. At that point I would like to post/get to paypal. The payment page is supposed to be returned and this is the page that I would like to forward to the customer so that they can log into paypal or continue without logging in, again that is the payment page.

I have been playing around with the HttpPost apache library. Something is not right. I have documented my problem here: http://forum.springsource.org/showthread.php?t=94075

I came across a different way to submit paypal parameters here:
http://code.google.com/p/divermate/s...pec=svn26&r=26
OR this: http://paypaldev.org/yaf_postst16691...x-problem.aspx

i tried to mimic the way the query string was supposed to be built:
String str = "cmd=_s-xclick";
str = str + "&" + "item_number" + "=" + "1";<br>
str = str + "&" + "business" + "=" + "my@emailcom";<br>
str = str + "&" + "currency_code" + "=" + "USD";<br>
str = str + "&" + "amount" + "=" + "55";<br>
str = str + "&" + "item_name" + "=" + "PiT Words";<br>
str = str + "&" + "no_note" + "=" +"1";<br>
str = str + "&" + "return" + "=" + "http://localhost:8080/ZZZ-web-0.0.1-SNAPSHOT/welcome";<br>
str = str + "&" + "hosted_button_id" + "=" + "7D3BWZZZ87AME";<br>

I even tried using :
URLConnection such as:

URL u = new URL("https://www.paypal.com/cgi-bin/webscr");
URLConnection uc = u.openConnection();
uc.setDoOutput(true);
uc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
PrintWriter pw = new PrintWriter(uc.getOutputStream());
pw.println(str);
pw.close();

following this example from paypal: https://www.paypal.com/us/cgi-bin/we...es-pop-outside
BUT this was for command: cmd=_notify-validate
NOT for cmd=_s-xclick but I assume it is set up the same way.
I also tried using HTTPGet and HTTPPost...but nothing is working....
I am lost..

it just behaves differently with cmd=_s-xclick vs. cmd=_xclick ...OR it keeps saying there are is stuff missing OR it comes back with an empty response....or it says bookmarks are expired....this is crazy..not to mention the button that I genrated...am I supposed to include that....according to this I am:
http://code.google.com/p/divermate/s...pec=svn26&r=26

but when I do the exact same thing I get a blank response.

can SOMEONE please post a working example of website payment standard that I can do a POST or GET to paypal from my java application. All I want to do is display the Paypal Payment Page to the user...please a working example..thank you so much...

hi,

For this you need Apache HttpClient (http://hc.apache.org/downloads.cgi) libs. This makes tasks lot easier.

This is for HttpClient 4.1 library..

public void yourMethod () {

HttpClient httpclient = new DefaultHttpClient();
HttpParams myParams = httpclient.getParams();
HttpConnectionParams.setConnectionTimeout(myParams ,40000);
HttpConnectionParams.setSoTimeout(myParams,40000);
HttpPost httppost = new HttpPost("https://www.paypal.com/cgi-bin/webscr");

try {
// Add your data
String url = "https://www.paypal.com/cgi-bin/webscr?"; // or sandbox url here
url += "business=" + "email@address.com" + "&";
url += "cmd=" + "_xclick" + "&";
url += "amount=" + "20.00" + "&";
url += "item_name=" + "item_name" + "&";
url += "item_number=" + "item_number" + "&";
url += "quantity=" + "1" + "&";
url += "currency_code=" + "USD" + "&";
url += "no_shipping=" + "1" + "&";
url += "rm=" + "2";

HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpclient.execute(httpGet);

InputStream is = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder str = new StringBuilder();
String line = null;

while((line = reader.readLine()) != null){
str.append(line + "\n");
}
is.close();
String responseText = str.toString();
getContext().getResponse().getWriter().write(respo nseText); // Simply print the responseText string
}
catch (Exception e) {
//TODO: handle exception
}

}

The POST method didn't work..
Hope this helps..

Hi,
I am a beginner tospring and web application.
I have an application spring-mvc that will have the "Pay Now" button on a jsp.
In the jsp, when click PayNow I use:
doSubmit(document.forms['<c:out value="${mdl.modelName}"/>'],'payNow');

in the controller I have:

public ModelAndView payNow(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse) {

HttpClient httpclient = new DefaultHttpClient();
HttpParams myParams = httpclient.getParams();
HttpConnectionParams.setConnectionTimeout(myParams ,40000);
HttpConnectionParams.setSoTimeout(myParams,40000);
HttpPost httppost = new HttpPost("https://www.paypal.com/cgi-bin/webscr");
try {
String url = "https://www.paypal.com/cgi-bin/webscr?"; // or sandbox url here
url += "business=" + "email@address.com" + "&";
url += "cmd=" + "_xclick" + "&";
url += "amount=" + "20.00" + "&";
url += "item_name=" + "item_name" + "&";
url += "item_number=" + "item_number" + "&";
url += "quantity=" + "1" + "&";
url += "currency_code=" + "USD" + "&";
url += "no_shipping=" + "1" + "&";
url += "rm=" + "2";

HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpclient.execute(httpGet);

InputStream is = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder str = new StringBuilder();
String line = null;

while((line = reader.readLine()) != null){
str.append(line + "\n");
}
is.close();
String responseText = str.toString();
getContext().getResponse().getWriter().write(respo nseText); // Simply print the responseText string
}
catch (Exception e) {
//TODO: handle exception
}
}

I copied the code posted above by Rukmal Dias in my method, but my method have to return :
return new ModelAndView(?????);

Can anyone ask me how return the Paypal response from my ModelAndView payNow(HttpServletRequest httpServletRequest,HttpServletResponse httpServletResponse)

Thanks

[rukmaldias]

hi rita
In here u need to redirect to pay-pal server/web page...

try some thing like this,

// Return type void / any type
public void payNow() {

boolean test = true;
String url = "";

url += (test)? "https://www.sandbox.paypal.com/cgi-bin/webscr?" : "https://www.paypal.com/cgi-bin/webscr?";
url += "business=" + ownerEmail + "&";
url += "cmd=" + "_xclick" + "&";
url += "amount=" + "20.00" + "&";
url += "item_name=" + "user_signup" + "&";
url += "item_number=" + "item_number" + "&";
url += "quantity=" + "1" + "&";
url += "currency_code=" + "USD" + "&";
url += "no_shipping=" + "1" + "&";
url += "rm=" + "2";

getContext().getResponse().sendRedirect(url);
// Use this or any redirecting method in your framework.
}

Note: you need to log in before testing pay-pal test account. Otherwise it gives a 'Please login to use features' or some message.

Thanks rukmaldias,
the payment on paypal works, now I have to test the return of the transaction from paypal.

Paypal 's example for java/jsp about IPN listner is very poor, have you a template for spring MVC thath I cau use ?

I think that is better write a class for listner, is it right ?

Thanks
Rita
