View 3 RepliesI 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.

1) How to Call Java base API's Through VB.Net 3.5
2) Is it a feasible approach to call Java API's through VB.Net as these 2 are different platform?
In order to call a java class in vb, I found the following procedure and I tried.
(1) create a java class (eg: MyTest .java)
as
public class MyTest
{ public int myfunction(int value1, int value2) { return value1+value2; }
(2) compile to get a MyTest.class
(3)register Mytest.class using javareg.exe file from Microsoft SDK for Java using javareg /register /class:MyTest /progid:MyTest and see a MessageBox displayed with Succesfull register Class message
(4) copy MyTest.class to C:WinntJavaTrustlib
(5) open a New Project on Visual Basic. And paste this brief code on the Form Load event for example and run it. Set x = CreateObject("MyTest") MsgBox x.myfunction(1, 1)
I did all the above steps but when I run the vb program (Step 5), I get the error message "Cannot create ActiveX component". Unhandled Exception message.
I am using Java 1.5 and Visual Studio 2008.
This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
I had deploy a program to call Java Web services from VB.net . Below is my code:

after run the code, I had get soap error code 500 after soap.send(), is that anything wrong with my program ??
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 have web page with four grid views. Each grid is hidden under a div tag. Whenever user clicks on div the data grid corresponding to the div is shown. I have binded data to the grid views at the page load only, since the data size is huge I cannot load the data binding at the page as the time taking to page load is huge. I was thinking a way that grid view gets data loaded only when user clicks on the corresponding div tag
View 2 Replies[URL] The jist of the problem is in fact that in the weka.classifiers.trees namespace you have the following members:
namespace weka.classifiers.trees.j48
and
public class J48 : weka.classifiers.Classifier (Member of weka.classifiers.trees)
Lamentably VB .NET in VS 2008 does not seem to be smart enough to distinguish betweem the two (which is odd, because there is no such problem in VS 2003, or in C# in VS 2008) because of it's lack of case sensitivity. Or possibly because of the fact that ikvmc emits an assembly compiled for the 1.1 run time... I'm not sure. I'm also not quite sure how you would resolve this particular issue and given the time sensitivity of this project I do not have the time to learn C# or Java to an extensive degree.
Wrote a 'webservice' with Netbeans wizard, runs on glassfish. I added a reference using the wsdl to my .NET client, VB if it makes any difference.The issue is a SoapHeaderException.

SoapClientMessage message, WebResponse response, Stream responseStream,
Boolean asyncCall)

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 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.
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 have been deploy webservice in vb.net .

I call upon your combined intellects. I have a web application with a silverlight app that calls a ria service. The ria service is defined inside the web application and everything else is just dandy.
The issue is this.It is my understanding that in order for the silverlight application to talk and know what the ria service is, you need to add a service reference for that service. The service reference defines the ria service and sets up the connection binding. One of the files it adds is the ServiceReference.ClientConfig which has the connection binding in it. During the course of this application's development, this is the way it was set up. And it worked perfectly fine locally and on the dev server.
Unfortunately there were issues when deploying to the clients in-house server. At this point I was onto other projects while my co-worker continued with the deployment. He soon became frustrated with the goofy errors that were occurring and recruited some help. This dev came in and, albeit got it working, but in order to do so he removed the service reference from the silverlight project but left the ServiceReference.ClientConfig which pointed to the location of the service in the web application(but that's it, no definition or explanation as to what the service does and I'm not sure how the silverlight app is supposed to know how to work with it..). This works perfect on my co-workers workstation and he has deployed this version to the clients server fine.
When I open the project it doesn't run at all. And the reason why is that it doesn't know what the service is that i'm using in code. Specifically, it doesn't know where this is (names changed for clarification):
Imports SilverlightApp.ServiceReference.WebApp.Service
I have cleaned the solution, completely deleted and got the latest from source control, built the web app first and made sure the asp.net dev server was running so that the address in the ServiceReference.ClientConfig resolved correctly. But, alas, it still doesn't know what Imports SilverlightApp.ServiceReference.WebApp.Service is.
So, to get it working on my workstation, I added the ServiceReference back but kept the current connection bindings so that it matched the endpoint in the web app web config. and changed the import statement to Imports SilverlightApp.ServiceReference and everything works fine.
Is it possible in .net 2.0 to enable calling web service only from localhost and to disable calling web service from outside?

View 1 RepliesI have been given the task of calling a web service which returns an xml data feed which I am doing like so:
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
Next
This is all fine but as you can see x just gets overwritten with every iteration. What I need is create an xDocument and add each feed from my loop but I am unsure how to proceed.
Solution
Dim xAllFeeds As XElement = New XElement("Feeds")
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
xAllFeeds.Add(x.Root)
Next
When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue. CWWSS5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.Is it even picking up the credentials that I am trying to pass? At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.

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.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
