 |

I have been trying some ASP.NET projects from www.codeproject.com.
All of them are OK on IIS server.
Abyss Web Server X1 2.5 on same machine, same folders, everything set according to your instructions could not run some of them.
For example, see the simple 1-page aspx: | Code: | <%@ page language="vb" AutoEventWireup="true" %>
<%@ Import Namespace="System.Web" %>
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Text" %>
<%@ Import Namespace="System.Xml" %>
<html>
<head>
<title>Demo International Prices</title>
</head>
<body >
<script language="VB" runat="server">
'Load the conversion rate file
Public Function getConversionRate(ByVal sFromCurr As String, ByVal sToCurr As String) As Double
Dim req As HttpWebRequest
Dim res As HttpWebResponse
Dim srExRateData As StreamReader
Dim s1ExRateData As String
Dim separator As Char() = ","
Dim dRate = 0, dRate1, dRate2 As Double
Dim oExRateData As System.Xml.XmlDocument
Const s1ExRateSource As String = "http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"
Try
oExRateData = New System.Xml.XmlDocument
srExRateData = New StreamReader(WebRequest.Create(s1ExRateSource).GetResponse().GetResponseStream(), Encoding.ASCII)
oExRateData.Load(srExRateData)
srExRateData.Close()
dRate1 = getEuroRate(oExRateData, sFromCurr)
dRate2 = getEuroRate(oExRateData, sToCurr)
dRate = dRate2 / dRate1
Catch
End Try
Return dRate
End Function
'get a rate note from the xml
Function getEuroRate(ByRef oExRateData As System.Xml.XmlDocument, ByVal sCurr As String) As Double
Dim oExRateNode As System.Xml.XmlNode
oExRateNode = oExRateData.SelectSingleNode("*/*/*/*[@currency='" + sCurr + "']/@rate")
If Not oExRateNode Is Nothing Then
'Return CDbl(oExRateNode.Value)
Return Val(oExRateNode.Value)
Else
Return 1
End If
End Function
'Return the price
Public Function PrintPrice(ByVal dPrice As Double, ByVal dRate As Double, ByVal sCurr As String) As String
Dim sReturn As String
sReturn = "N/A"
if sCurr="USD" then sCurr="$US"
if not sCurr="" then
sReturn = (dRate * dPrice).ToString("#.##") & " " & sCurr & "<sup>*</sup>   "
end if
sReturn += "GB£ " & dPrice
return sReturn
End Function
</script>

What is the problem? It works on IIS.
Thanks |

The first reported sample works on Cassini, too.
Next problem:
Try to run the VB or C# sample from this article
http://www.kbsoft-group.com/Use_of_the_PayPal_payment_system_in_ASP.NET.htm
Again, everything was set and running fine on IIS.
Using Abyss Web Server, the sample works incompletely;
the PostBack behaves differently and “Object reference not set to an instance of an object” error appears in the log file.
……………………..
And … my last question:
You answered on this forum, (see theVOJ’s thread):
“theVOJ,
Please contact our technical support to get an updated version of the ASP.NET connector that solves that (his) problem”
Is this “updated version” already available?
Thanks. |

ninobg,
We tested both applications (the simpel ASPX script quoted above) and the Paypal sample and they worked fine with no problems. So could you please explain us how you configured Abyss Web Server ASP.NET paramters?

Thanks,
Agree for the quoted sample. I found what was wrong.
Hovewer the PayPal application from the link still has troubles.
The settings are:
- MS Windows XP
- fresh default install of Abyss Web Server x1 2.5
- fresh install of Net.2 framework
- only server ASP.NET aplication is the sample in question
- the application is in subfolder /paypal inside htdocs
- Host > Configure > ASP.NET Parameters, Add /paypal ; and type 2.0 selected
- All pre-work regarding application itself is done properly - account on paypal sandbox, web.config settings etc.
- The application is tested with other server+aspnet engine - works fine.
(in web.config the setting is <add key="SendToReturnURL" value="false"/>, that means "NotifyUrl" and IPNHandler will be used)
When Abyss server is used, everything looks "almost" correct, except that
the IPNHandler doesnt process the back request like the with the alternative server engine.
Log always has: Error in IPNHandler: Object reference not set to an instance of an object.
Should be: "Success in IPNHandler: PaymentResponses created"
I did the test above 10s times on three different PC/setups and always the same result appears.
I tested also with "alias" and virtual subfolder's settings - same thing.
What else I could change?
Thanks |

So we need to check it again. How can we reproduce the error? (the exact steps, URLs, and links to visits would help us quickly check the problem and understand what's going on).

In order to reproduce my findings, please follow the steps:
1. Create one main account on http://developer.paypal.com/.
2. Follow their instructions and create two sandbox test accounts - one for buyer another for seller.
3. Log in as seller and go to Profile Instant Payment Notification Preferences Click on Edit and check the box under “Activate Instant Payment Notification” paragraph.
Make the “Notification URL address” field blank.
Click on “Save” and check if the Instant Payment Notification is ON
4. Unpack the sample from http://www.kbsoft-group.com/Use_of_the_PayPal_payment_system_in_ASP.NET.htm to subfolder /paypal inside htdocs
Create an internal sub folder /paypal/Log if doesn’t exist.
5. Open web.config and change the strings according to your IP (or hostname)
- choose sandbox setting
- make sure that /paypal is valid server path (follows)
- change the following key key <add key="SendToReturnURL" value="false"/>,
6. Abyss Console: Host > Configure > ASP.NET Parameters, Add /paypal ; select 2.0
7. Run the server and address the application (ype the ip/paypal or hosname/paypal if is DNS registered)
!!!Make sure your server is available from internet!!! (D'ont use "localhost" or so)
8. Open another browser to confirm that you are still login to http://developer.paypal.com/ . If not, just login again. (Otherwise, the paypal sandbox will ask you to do so at one point before payment and payment sequence will be interrupted)
9. Test one transaction (use buyer's account to pay !! Don't return to sellers page !!) and check the log file in /paypal/Log.
10. Repeat the same, but by using IIS
11. Compare the results. In my case for similar transactions, on last log line I have:
Abyss: Error in IPNHandler: Object reference not set to an instance of an object.
IIS: Success in IPNHandler: PaymentResponses created |
