Getting A Response With A .NET Client From A Java Web Service?
May 26, 2011
Here'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:

I had a problem getting a VB.NET web service client to receive the response object from a Java web service.In the process of posting this question someone from another department volunteered some code written for a similar situation.I couldn't find this anywhere on the net so I'm completing my question to help others out.[code]The web service is Apache CXF with some Spring elements mixed in.

I am implementing a VB.NET desktop application which consumes a web service.
The web service implemented in Java and I currently using Tomcat on my localhost to host the web service.
The web service requires secure communication with the client and so I have followed instructions that outlined how to use Java's keytool.exe to create two .jks keystores (one for the client and one for the server) and then create two .cer certificates (one for the client and one for the server)
I have placed the keystores and certificates generate into the directory where the web service is expecting them (according to the instructions)
I have installed the certificates into TrustedPeople and have attempted to use the certificate by setting the ClientCredentials.ClientCertificates property like this:
myServiceProxy.ClientCredentials.ClientCertificate.SetCertificate(storeLocation.CurrentUser, StoreName.TrustedPeople, X509FindType.FindByIssuerName, "name")
I keep getting the following error message when I try to call any method:
An error was discovered processing the <wsse:Security> header
My problem is that I don't know how to use this in the VB.NET client application that is consuming the web service. I could be doing this completely wrong.

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?

I 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:

This 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)

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.

I 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.

I've tried writing the string in a soap envelope, but still receive the same message. So passing a string is kaputt, as it should be; why would the WS know to parse a string, and simply instantiating and calling the method from the object as if it were local isn't working the way I think it does.

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.

We had plan to create a three tiered architecture database application, where the middle tier will be implemented using Web Service. We're going to use Linux for the server, so I think for the web service to be able to be implemented, we only had PHP/Java left. Is this right?
The constraint is, we're going to use VB.NET for the client application.We already had a two tiered VB.NET application from our last successfull database application. It use a lot of DataSet for the result of SQL execution. Now, what I had in mind, is a simple approach of converting all procedure that return a DataSet Object, to be a WebService method. But, because of this thinking, I don't think we can do it in Java/PHP. That is, we'll be enforce to use a ASP.NET approach. Is this correct? I assume my answer from this article Consuming a DataSet from an XML Web Service (ADO.NET)

I am using a client.openRead to send request and passing line through finalurl.
Dim data As Stream = client.OpenRead(finalurl)
Now my server blocks ports and i am getting error on this line now is there any other solution to client.OpenRead and what ever i am sending throught this is code is going on other company's server so i can't tell then to change their way so is there any other solution to this?
I AM THINKING THAT IF PORTS THEN IMPOSSIBLE TO SEND REQUEST.SO ONLY WAY IS TO CHANTGE SERVER WHER I HOST MY SITE
Dim data As Stream = client.OpenRead(finalurl)
And in final url i have other sites url and some querystring data
For example
dim finalurl as string= [url]
I already use WebHttpRequest but it not works still server not allow it.But i try it with response.redirect and it works but not suiteable to my conditions.i want control on my site so i was using Dim data As Stream = client.OpenRead(finalurl) but now server block some ports due to some reasons

Is it possible to view client transaction requests and host response in a self hosted console window?
Front end client sends request to service
Service console displays requested data in console window and forwards to listening server
Server responds with data
Response is displayed in console window
I guess it would be displaying the traces in the console window.

i have a WPF application that uses a service reference to a web service.Now i have a GUI component that tracks the progress of this...But i seem to have some sort of bug here, it only occurs on some machines and not often..I start a call with MethodNameAsync and display the progress bar until the matching Completed event occurs.
some times i call 3 different async methods in a row but only the two of them get their Completed event raised so the GUI will be locked and the application has to be restarted.After being totally frustrated a few weeks i found the event AppDomain.CurrentDomain.FirstChanceException, so i hooked up to it and started logging all FirstChanceExceptions..
[Code]...
Fix this temporary by not using async methods and instead using a thread that will call them one by one.. now this is not a elegant solution, i should be able to use the async methods...

I have a small program which is a tcp client. I send a string from this client to a device over ethernet (it acts as the tcp server). As soon as the device recieves the input string it will respond back with response data. My problem is i am not getting the entire response data back from the server. (device).
Dim serverStream As NetworkStream = clientSocket2.GetStream()
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("my-cmd")

I have a 3rd party webservice (happens to be a peoplesoft EIP service) that I'm trying to call from .net. I've tried using a service reference and the old web reference to call this service and every time I call it I get a response of "nothing" back from the service.
I've ran the service call through SoapUI and it works fine. I've captured the network traffic using Fiddler and notice that when i call the service from SoapUi or from .Net I get the same resulting xml back from the call. So that means the call is working. I've turned on tracing and logging within WCF and I'm not seeing any errors. Nor is it throwing an exception.
So my theory is that .net is having a hard time translating the xml from the service back into a .net object.
Here is a snippet of my code:
Dim psclient As New psService.LSS_WEBORDER_PortTypeClient
Dim psreq As New psService.LSS_WEBORDER_REQ_MSG_TypeShape
psreq = New psService.LSS_WEBORDER_REQ_MSG_TypeShape

I have a solution in VS 2010: a WCF Service Library project ("NotifyService") and two Windows Forms projects, one for a server ("NotifyServer")and one for a client ("NotifyClient"). My goal is to have a duplex WCF service that will notify any number of connected clients when the server pushes out a notification. The clients do not need to communicate to the server except to subscribe and unsubscribe from the server's updates. However I seem to be running into problems nailing down the InstanceContext.
Here's the code for the WCF service:
<ServiceContract(
CallbackContract:=GetType(INotifyCallback),
SessionMode:=SessionMode.Required)>
[Code].....
Since I'm setting everything up through code, there are no app.config files. The problem I'm having is that my Subscribe method is never called. When debugging, I get an error after stepping through that line (not an exception) that says "Unable to automatically step into the server. The debugger failed to stop in the server process." When I go back to my server form and click the button designed to raise an event on the callback clients, it steps into the NotifyService class but the _callbacks list is empty, meaning the Subscribe method either never ran, or it never ran on that instance.
I have fought with this for almost a week. This is nearly an identical copy, at least on the service-side, to what was described here, and I've compiled that and it works.

I have written a VB.NET windows service application. I installed it in my system using the Installutil.exe. But this is not available in the client's system because the .NET is not installed in that system.Is there any way to install the .NET windows service application without the Installutil ?
