View 1 RepliesThis is related to my question at the below link, however posting on a seperate thread as needed some direction on the error handling part.soap request client to webservice using vb.net
How/Where can i get the error "response validation not conforming to wsdl and schema" in my vb.net webservice client. I checked the response using the validate response option, within soapui tool. Is there any way to generate the logs related to this, in .net client?There was no exception in my .net client, except the response object was blank, even though i could see the response xml in the trace log.
The below line invokes the webservice. After the excution, tracelog has the request and response xml, however my objresp(response object) is empty. In soapui, i validated the response, it was not conforming to schema.objresponsehead = objProxy.myoperation(objreqheader, objrequest, objresp)
I have to query once an hour to a remote web server to recieve data. However the remote web site does not use web services and state in thier 300+ page document that:
Although SOAP is a recognized Web Services API, the RTO web server does not offer a web services interface. That is, there is no Web Services Description Language (WSDL) file available for usage by participant web services client software.
So my question is how do send a soap request and get a response without the use of a WSDL?
I'm trying to get data from a webservice, returning just one result, the number of a given item in stock.
I'm successfully getting a result, but need to strip all the XML code from it to simple return the number, the XML being returned looks like:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
[Code]....
With just a couple of tweaks to get the data correctly, most notably changing the content type to application/soap+xml and passing the data as XML.
I am using VB with ASP.NET 2.0.
I need to handle a soap request and send a response in a single string. My response is going well but I can not see a request string in my log file thought protocol analyzer can see it properly.
View 2 RepliesThis is my first time using SOAP with anything. I have an interesting situation, I have to send query's via soap to a secure server and get a response back and then import the response into a database. I have the connection to the secure server figured out and importing the returned xml figured out. I followed examples however I get nothing back in the service windows from the remote web site.
Here is my vb.net code with the soap request inside:

Am pretty new to web services and have been trying to implement Soap Faults. I used Apache Axis2 to generate webservice in the following manner.
[Code]
Now, I created a dynamic project using Eclipse and with the help of Axis2 plugin I created webservice for my "Webservice" class which generates wsdl file. I deployed the webcontent in the Tomcat folder and able to access the WSDL file in the .Net environment. I am able to pass array of objects (User[]) from .Net to Java and able to do my task. Now, I need to implement Soap Faults in Java which I am not sure how to implement.
I have created a WCF VB.Net Soap service. The service compiles and runs, but at runtime, only half of the variables passed to the function via a soap request are received.

I'm building a .NET component that will call an external web service. I used the "Add Service Reference" dialog to add the web service to my component, which generates the code needed to consume the service and adds the settings to the app.config file.I'm testing the component by adding a reference to its DLL from a Console application and calling the appropriate method that creates a new instance of the web service: ... = new MyServiceSoapClient(). However, when I do this, I get the following exception:
InvalidOperationException
Could not find default endpoint element that references contract 'MyServicesSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.This makes sense since the app.config isn't being brought over with the component's DLL. How can I call the web service without having to rely on the settings in the App.Config?

View 1 RepliesI need help with something it drives me nuts. I have an application which send XML to a web server through a POST method. This part works excellent. But where I have issues is with receiving the standard response from the web server for OK or error. Instead of receiving the actual response, I get the error message" WebException was unhandled. The server committed a protocol violation. Section=ResponseStatusLine" . The response I should receive is in XML format where I have as elements the error result (ok or error), the error number and the error description. Here is the code I have:

Does someone know If Response.Redirect can be used inside a method of a web service. I'm trying and I get an error. If I use it outside of the web service I have no problems.
View 6 RepliesI have a windows service that utilizes an infinite loop and thread.sleep. The sleep time for the thread is 10 seconds.When the service is initially started AND has work to do (data exist in SQL), it immediately does it's processes. It continues to be responsive and process tasks every 10 seconds as long as it has work to do. If no data is present in SQL for an extended period (i.e. 15-20 minutes) then the service starts responding very slowly. It will eventually pick the data up and process it, but it takes more like 10 minutes instead of 10 seconds.
View 2 RepliesHere's the situation. I'm a Java developer. Another developer in our company wrote a web service for our clients. They wrote the service in Java. They also wrote a demo for creating a client to consume the web service in Java and it works just fine. I've been tasked with creating a web services client in VB.NET to do the same thing. It hasn't been going smoothly. The problem is that the web service requires that you send the username and password in the SOAP header and I can't figure out how to do that in Vb.NET. I looked at the following pages:

View 1 RepliesI wrote a soap service in PHP using nusoap. It works fine with the test client I wrote in PHP, however, our customer wrote his client in vb.net and it is not working. There are no errors that I see, but the service is not parsing his requests properly.
I am letting nusoap generate the WSDL, and it looks fine. If I compare a message that I send in to one of his messages, I do see a few differences in the envelope, but I'm not sure if the problem is on my end or his.

I have a VB.net web service that returns JSON that works fine. Once the response gets to a certain size though, the client browser says that the server has closed the connection and sent no data. This is true using IE, Chrome, or Firefox. The magic size seems to be about 16383 records, or about 1.13MB of data. I know this is slightly large for a web service.

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
i made a tcp/ip application using the .NET TcpListener class, my problem is that sometimes (about 30 / 4000) the connection between the client and the server got interrupted in the middle and the server response to the client is lost.is there a way to know if the server response was successfully sent to the client without the client response back?

View 3 RepliesI need to use a web service that was provided to me and that uses SOAP with attachments as a means of communication. It also uses WS-Security 1.0 as a form of authencation (user and pass in plain text).I will be working on VB.NET and my experience with web services is very slim, and goes as far as creating a WCF web service, adding the service reference in another project thus creating a proxy class and using the methods.I have searched the internet and found that there is no native support for SwA in VB.NET, is this correct?
View 3 Replies I am currently working on a project, which purpose is to call a webservice through a VB script. VB is by far not my first language and I simply reach the point where I do not know how to go on from here.
I have a Webservice descriped in a WSDL document that defines a service that takes a complex type as parameter and returns such one as answer.
The complex type is basically just a string that is wrapped inside a class object. So what i did was to create a new class module and added a public variable to it. I created a new instance of this class, gave it for the purpose of testing a value and tried to call the webservice. Everything goes well untill i reach the call to the webservice, where the program throws an exception that says:
"Class does not support automation or does not support expected interface"
My first thought was that the initialization of the object might have gone wrong but i am quite able to set and get the values on it. So i have to assume that the object is okay. I know that the url to the WSDL document is correct, due to the fact that I can call the document via the browser and it will throw an exception of "wrong type" when i feed the soap method with a primitive.
With out luck I browsed several pages on the net to find a clue what this could. So now i wanted to give this forum a shot.
You should know that i am not able to alter the WSDL file. I have to go with the way it is. In addition am supposed to stick to VB 6.0.
I used a Form in VB to make the call to the webservice.
Here is the call procedure:
Private Sub Command1_Click()
On Error GoTo ErrorHandler
Dim tS

It's the first time that i'm trying to use SOAP, i don't know how to make the request, I know the URL where the operation it's located, and i know the name of the operation, and i know the expected xml document schema. I have read in msdn about Microsoft.Web.Services2.SoapEnvelope, but i'm missing something...
The function structure it's something like:
<normal soap nodes until body>
<NameOfTheFunction xmlns="http://tempuri.org/">
<Var1>Value1</Var1>
<Var2>Value1</Var2>
Do i need the webrequest class? or the soap class can do all the job?
