I'm developing a .NET application using .NET 3.5 .My application is using a JAVA
WebService (wsdl url)
When I run the application I want to consume the web service (wsdl file) written in XML. i either keep getting the Operation Time out Error or the following exception while debugging
Possible SOAP version mismatch: Envelope namespace
http://schemas.xmlsoap.org/wsdl/ was unexpected.
I am trying to consume an array of strings from a webservice that I wrote. I keep getting the error: "System.NullReferenceException: Object reference not set to an instance of an object."
I know I am doing some thing wrong at an extremely basic level, but it's not coming to me.
I have tried adding New but get the error that you can't declare arrays with New
Here is the dummed down webservice method:<WebMethod( _
Description:="Testing ")> _
Public Function TestArray(ByVal Address1 As String, ByVal zip As String) As String()
Dim strTest(4) As String
strTest(0) = "It's"
strTest(1) = "a"
strTest(2) = "great"
strTest(3) = "day"
Return strTest
End Function
<--Here is the call that generates the null reference error-->
Private Sub FindAddress()
Dim svc As ws.Service
Dim strAddresses() As String
strAddresses = svc.TestArray(txtAddress.Text, txtZip.Text)
End Sub
how to consume a webservice from Brazilian Correios (kind of USA Fedex).
The Web Service address is [URL]
The instructions says that I need to use the method CalcPrecoPrazo and send those parameters listed below (I already filled the variables with the correct content to help you use that webservice).
Dim nCdEmpresa As String = ""
Dim sDsSenha As String = ""
Dim nCdServico As String = "41106"
Dim sCepOrigem As String = "87047130"
Dim sCepDestino As String = "80610320"
Dim nVIPeso As Decimal = 1
Dim nCDFormato As Integer = 1
Dim nVIComprimento As Decimal = 20
Dim nVIAltura As Decimal = 30
Dim nVILargura As Decimal = 30
Dim nVIDiametro As Decimal = 0
Dim sCdMaoPropria As String = "N"
Dim nVIValorDeclarado As Decimal = 0
Dim sCdAvisoRecebimento As String = "N"
The result will be send by the parameter RESULTADO.SERVICOS in a array format.
I am trying to consume a webservice. I added the web reference. But when i try to access the method, I am getting the error as:"The request failed with HTTP status 401: Unauthorized."The web service has username as "user1", password as "pass".I tried this:
Service1.TestPrcsService serv = new Service1.TestPrcsService();
serv.PreAuthenticate = true;
serv.Custom_methodname(true);
How to pass the username and password to access the method?
I am trying to write a webservice that's going to be used through ASP.Net Ajax. In this webservice I have to add exception handling so that in case of any error, I could log them to some central place and then throw.
In my other areas of code (like aspx pages), i have been using a basepage which Overrides System.Web.UI.Page class's OnError by adding a custom event handler. I want to do the same for my webservice as well.
Basically I do not want to decorate each webservice method with a Try Catch block. Instead if there is a clean way like to override the on error method, i want to go for that. Unfortunately the WebService class does not seem to have any functionality for this.
I have a classical asp.net web service (asmx) and a web method in it. I need to throw a custom exception for some case in my web method, and I need to catch that specific custom exception where I call the web service method.
[Code]....
However, I cannot do that because when I add the web service reference on the client, I have service class, input and output classes, but I do not have custom exception class.
Also another problem is that, I have also problems with serializing Exception class (because of Exception.Data property implements IDictionary interface)
Is there a way to do this in my way, or am I in a completely wrong way, or is there something I miss about fundamentals of web services?
I have a web service that runs a query (from C#) to get a dataset from sql server. I get the following time out error. Googling on this error says, you can set the timeout on command object. But I am not using command object to set the timeout. This is the code I am using to get the dataset.

I was created webservice which has a Method:
[Code]....
Then, in my aspx page, i call that method in javascript, but i get a Exception message is "Authentication Failed", code below:

How to resolve this problem?

I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.
In ASP.NET,How can i know the Specific details about an exception (like What kind of Exception it is (FileNotFound /Arithmentc etc..) )from a General Exception class object.

Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this
public int AddMethod(ContactClass contactObj)
{
int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
I'm taking over a project for a former co-worker. We're consuming a web service which requires authentication. The former co-worker was unable to call the service using WCF. I'm mostly unfamiliar with web services but was also unable to get it to authenticate.Upon speaking w/ the original developer, I was told that I'd have to build a project in VS 2005 in order to consume the service and that WSE 3 would have to be used, instead of WCF. He has some code that did indeed build and run on his PC, while he was here. I'm now unable to get it to build.
I'm running VS 2005 on XP and have WSE 3.0 installed and enabled on the project, which is a C# class library. I successfully made a Web Reference to the service and generated a proxy. In trying to test it, the first few lines of my code look like this:
[Code]....
...problem is, it says that the proxy that was generated does not have RequestSoapContext!
I am trying to create a wrapper class for the MusicBrainz CD database using VB.NET. I have a test URL that produces an XML response:[URL]I need to get that response into an XMLDocument object in .NET. I have tried XMLDocument.Load, WebClient.DownloadString, and HttpWebRequest through a StreamReader. All produce: Unable to Connect To Remote Server. It is possible that my company firewall is the problem but I can access the URL just fine in a web browser.

I'm working with an outside company to impletement their API into our program. Most of their member functions working pretty solid. I get to the one function where I have to pass an associated array to it and this is where it blows up. I create a hash table or namevaluecollection and of course I will get the error(The type System.Collections.Hashtable is not supported because it implements IDictionary.), which can't be serialized.
Is there an easy way to pass this associated array to them? I don't think their api is very flexible, but they seem to think so.

Is there any way to uniquely identify a particular exception from the general exception class.
i.e any property or method that retrieves a unique identifier that to identify a particular exception.
I have kept some error values and corresponding error texts in an xml file. I want to read that xml file and have to taken the error ids and fix the corresponding texts to a label. in the case of a system exception we have to identify a particular exception.
Difference between Exception and Fault Exception..?
Can i use Fault Exception when i get the Exception.

I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.I can access the proxy class from metadata, and it's of typeSystem.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.I realize that this is all old technology, but I don't get to decide what the servers run :(
